Paul’s reasoning

How did Christianity become the baffling religion it is today? A cloud of obscurity surrounds the first decades of the Christian movement. A few things we do know. Jesus started Christianity, but Paul of Tarsus, better known as Paul the Apostle, turned Christianity into the religion we know today. Paul was first a Pharisee who devoutly observed Jewish religious laws before becoming a follower of Christ. One thing we should know about Paul is that the scriptures were precious to him and more valuable than facts. Truth, in his view, is thus not, as Jesus taught, according to the facts as established by the senses, but according to the scriptures. And most people, religious or not, would not object to lying for a good cause, so it is not that strange.

How did Christianity become the baffling religion it is today? A cloud of obscurity surrounds the first decades of the Christian movement. A few things we do know. Jesus started Christianity, but Paul of Tarsus, better known as Paul the Apostle, turned Christianity into the religion we know today. Paul was first a Pharisee who devoutly observed Jewish religious laws before becoming a follower of Christ. One thing we should know about Paul is that the scriptures were precious to him and more valuable than facts. Truth, in his view, is thus not, as Jesus taught, according to the facts as established by the senses, but according to the scriptures. And most people, religious or not, would not object to lying for a good cause, so it is not that strange.

It is of the utmost importance, as it explains why Christianity has become the religion it is today. In Paul’s view, everything about Christianity should have a scriptural foundation. Paul’s education as a Pharisee is the reason why. We shouldn’t underestimate the consequences. Likely, most, if not everything, about Jesus that is ‘according to the scriptures’ is a fabrication. The label ‘according to the scriptures’ should serve as a red flag, signalling ‘invented by Paul.’ Hence, ‘Jesus rose on the third day according to the scriptures’ means ‘Paul made up that Jesus rose on the third day.’

It blows away the entire theological foundation of Christianity that Paul made up, including the idea of the New Covenant. That should come as no surprise if God is a woman who took a human form and married Jesus, telling him they were Eve and Adam reincarnate. It also suggests that the earliest document depicting the historical events, the Gospel of Mark, had already seen significant editing for theological reasons. If Christianity aligns with the Jewish scriptures, it gains credibility among the Jews. That was a good cause for Paul.

Christianity began as a small Jewish sect founded by an end-time prophet who claimed to be the Messiah. Many Jews awaited a Messiah but expected a strong leader who would liberate the Jewish nation from Roman occupation. Jesus didn’t live up to their hopes, and the Romans had him crucified. That wasn’t the end of Christianity, but just the beginning. Jesus later appeared to some of his followers, thereby giving credibility to his claims that he was the eternally living Son of God. That is possible in virtual reality, and it is hard to envision how Christianity could have survived otherwise. His post-death appearance gave his followers new hope and inspired them to carry on, leading to Pentecost and the belief in the Holy Spirit.

Paul, whose name was first Saul, was initially a fervent persecutor of Jesus’ followers. When travelling to Damascus, he received a vision. According to his own words, a bright light flashed from heaven, knocking him to the ground. He heard a voice he identified as Jesus accusing Saul of persecuting him. Today, we would call the experience a psychosis. The encounter temporarily blinded Saul. His companions led him to Damascus. There, Ananias, a Christian disciple in Damascus, restored Saul’s sight and baptised him.

It was a turning point in his life and an event that shaped the future of humankind. It was a personal calling. His response was not to consult any human being (Galatians 1:16). In other words, he didn’t go for a reality check. Instead, he went his own way and started preaching among the Gentiles (Galatians 1:15-16). Paul preached his own distinct gospel, which he claimed was revealed to him. He didn’t meet with most of the other Apostles for fourteen years (Galatians 2:1-10). He saw Simon Peter after three years, and also Jesus’ brother (Galatians 1:18-19). His mission succeeded. Indeed, God works in mysterious ways. In The Triumph of Christianity, Bart Ehrman attempts to reconstruct Paul’s reasoning, the foundation of Christian thought.

His vision proved to Paul that Jesus still lived as his followers claimed. Jesus had died, so he was resurrected, Paul reasoned. And therefore, he must be the long-awaited Messiah. That posed a few theological problems for Paul. The Romans had humiliated Jesus and executed him. So, why did Jesus have to die? Paul came up with an answer. In many religions, including Judaism during Passover, people sacrifice animals to please the gods.¹ The Gospels agree that Jesus died either on the day of Preparation for the Passover or on Passover itself. Now, that doesn’t seem like a coincidence, so that pushed Paul’s thinking in this direction. Paul must have known that Jesus believed himself to be Adam. Adam led us out of Paradise, and Jesus would return us to it.

And so, Paul reasoned that Jesus came to undo what Adam had done. The Jewish religion doesn’t place such a dramatic weight on the Fall. It definitely wouldn’t justify human sacrifice, or worse, murdering the Son of God. To make the argument work, Paul inflated the significance of the Fall to grandiose proportions. That is why Christianity, contrary to Judaism and Islam, places such an emphasis on sin. Paul turned Jesus into the sacrificial Lamb of God. In his view, we are all sinners because Adam was, but Jesus saved us by sacrificing himself. It is a novel idea not found in Judaism or its scriptures. The Jewish religion opposes human sacrifice, and it is even blasphemous to think that God would require it, so this is alien to Jews, which made Paul’s innovation truly remarkable.

The Lamb of God

The sacrificial lamb is a revolutionary new type of saviour, someone who, by his death, provides redemption to his followers. According to Mark, Matthew, and Luke, the disciples shared bread and wine during the Last Supper. And Jesus said, ‘Take it; this is my body,’ and, ‘This is my blood of the covenant, which is poured out for many.’ It is outside the Jewish tradition and part of the sacrificial lamb imagery. So, did Jesus say these words, or did Paul invent them? Probably the latter. Paul wrote (1 Corinthians 11:23-26),

For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, ‘This is my body, which is for you; do this in remembrance of me.’ In the same way, after supper he took the cup, saying, ‘This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.’ For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.

It begins with, ‘For I received from the Lord.’ In other words, the origin of this tradition lies in Paul’s imagination rather than in Jesus’ words at the Last Supper. He declared that he received the information directly from the Lord, not from an eyewitness. That is iffy. The Gospel of John fails to mention it. This gospel comes from a separate tradition outside Paul’s influence. John provides the origin of his line of thinking.

There, Jesus claimed that he was the bread coming from heaven in analogy to the bread that God sent from heaven in Moses’ time (John 6:25-59). Jesus declared, ‘I am the bread of life. Whoever comes to me will never go hungry, and whoever believes in me will never be thirsty.’ (John 6:35) And, ‘I am the living bread that came down from heaven. Whoever eats this bread will live forever. This bread is my flesh, which I will give for the life of the world.’ (John 6:51) And, ‘Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day.’ (John 6:53-54) According to John, Jesus said this while teaching in the synagogue in Capernaum.

It is the same imagery, but with a very different context: Jesus as a life-giver and bread from heaven. It relates to what John alluded to when he wrote that the Word became flesh, and that Jesus gave us the right to become children of God. As Adam, he fathered humanity with Eve, who was God, or so that was what Jesus believed. As Adam’s reincarnation, he was a life-giver with eternal life to offer his followers, since many Jews believed in the resurrection of the dead. That Jesus was Adam and eternally married to God, and thereby the father of humanity, was unthinkable for Jews, and also for most Jewish Christians, who didn’t know about Jesus’ love affair with God. Gentiles had no problem with that. They had organised themselves in the Johannine community around their own Gospel, now known as the Gospel of John, so you only find it there.

And so, Paul gave the eating of the flesh and drinking of the blood a different twist by turning Jesus into a sacrificial lamb. He borrowed his offering theme from another part of the Scripture, in this case Melchizedek’s offering of bread and wine to Abraham. In the first epistle to the Corinthians, Paul writes (1 Corinthians 15:3-5),

For what I received, I passed on to you as of first importance: that Christ died for our sins according to the scriptures, that he was buried, that he was raised on the third day according to the scriptures, and that he appeared to Simon Peter and then to the twelve Apostles.

It is another ‘for I received’ sentence, so many scholars believe these things have been passed on to him, possibly by fellow Christians as a creed, and that it reflects the earliest Christian beliefs.² However, the repeated reference to the scriptures makes the supposed creed suspect of being a product of Paul’s creative ingenuity. He has proven himself capable of writing a beautiful poem about love, so that wouldn’t be beyond his capabilities. A passage in Isaiah can explain the ‘died for our sins according to the scriptures’ (Isaiah 53:4-6),

Surely he took up our pain
and bore our suffering,
yet we considered him punished by God,
stricken by him, and afflicted.
But he was pierced for our transgressions,
he was crushed for our iniquities;
the punishment that brought us peace was on him,
and by his wounds we are healed.
We all, like sheep, have gone astray,
each of us has turned to our own way;
and the Lord has laid on him
the iniquity of us all.

You need not be too imaginative to apply this to Jesus, even though Isaiah had someone else in mind. Concerning the raising on the third day, Hosea 6:2 may come to assistance, as it says, ‘On the third day he will restore us.’ The larger the body of scriptures, the easier cherry-picking becomes. What comes next is even more unbelievable. Jesus supposedly appeared to more than five hundred at the same time. Paul was such a fantasist that it is unlikely to have happened.

Paul tried to answer the question of why God made Jesus sacrifice himself, which is a profoundly troubling question for a Jew. As a religious Jew, he looked for the answer in the scriptures, so facts were of secondary importance. Facts were never that important in religion, and are something scientists may care about. And humans are creatures who live by stories rather than facts. So, think of it as doing God’s work rather than lying. That was probably how Paul viewed it as well. And for good reason, because his diligent work united the early Church, a tremendous achievement.

So we should be cautious in concluding that Jesus believed that he had to die for our sins. The Gospel of John fails to mention it. John the Baptist calls Jesus ‘Lamb of God’ twice in the first chapter of John, but the other Gospels don’t mention that. It is an image from Pauline theology. There is no chance that John the Baptist said, ‘Behold, the Lamb of God.’ Although the author of John’s letter supports the claim that Jesus died for our sins, that could be telling. The letter expresses the author’s opinion, influenced by Pauline theology, whereas the Gospel of John is an existing account he redacted.

Jesus’ teachings were another reason Paul believed Jesus died for our sins. So, what did Jesus teach? It was the forgiveness of sins. Mark tells us that John the Baptist preached baptism of repentance for the forgiveness of sins, and that he baptised Jesus (Mark 1:4-9). These also became Jesus’ teachings. Jews already practised ritual immersion and washing for purification, spiritual cleansing, and as a conversion rite, so John the Baptist operated within an existing tradition.

Jesus began as one of John’s followers, a fact the Gospels don’t mention for obvious reasons. Instead, they say that John was the messenger sent ahead of Christ, thereby fulfilling a prophecy of Isaiah (Mark 1:1-3), which suggests that it is contrived. John the Baptist probably had said something like, ‘Jesus comes to take away our sins’ rather than ‘Behold, the Lamb of God.’ Nevertheless, it gives a possible answer to the question of why Jesus had to die, so the conclusion Paul arrived at is not far-fetched.

It leaves us with the question of why Jesus willingly went to the cross. Mark tells us that Jesus was deeply distressed and troubled. He prayed that the cup would be taken from him (Mark 14:32-36), which is a very different prayer from the one in John (John 17), where he hopes to await great glory. Many scholars think it is a later embellishment to explain that Jesus died in accordance with the will of God. Such an explanation doesn’t presume an intimate relationship between God and Jesus. And so, it probably was Jesus’ choice, perhaps made under duress. Jesus could have avoided the execution by rescinding his claims of being the Messiah and the Son of God. That would be denying the truth and his mission. Believing himself to be Adam and eternally living, he expected to survive, which emboldened him and strengthened his resolve. And don’t forget what people do for love.

Defining the Christian faith

It must have been God’s plan to save Her/His people this particular way, so by Jesus sacrificing himself, Paul reasoned further, so observing Jewish religious laws is not critical for your salvation, nor do you have to be a Jew. Jewish religious laws being irrelevant is another truly revolutionary thought for a Pharisee. Prophecies in the Jewish Bible foretold that all the nations would accept the God of the Jews. To Paul, Jesus was the fulfilment of these prophecies. After all, Jesus was Adam, the father of humankind. And from Adam, God made all the nations that inhabit the Earth (Acts 17:26), so Jesus’ message applied to everyone, not just Jews alone. There were already Gentile Christians, and Paul preached to them, so that was his view from the outset. Making them all adhere to Jewish religious law proved ‘a bridge too far’ and could hamper the spread of the religion. Paul then concluded that rejecting false gods and having faith in Jesus would be enough. Paul believed he was God’s missionary to spread the good news.¹

Paul was a knowledgeable scholar of the Jewish scriptures, whereas the other Apostles lacked such education. He shaped the beliefs of the early Church and the future Christian religion by establishing the theological foundation of the Christian faith. Paul defined God’s image as the Father, the amalgamation of the Jewish Yahweh and the Christian Mother Goddess. The result became a hybrid: a Father who can give birth. Jesus also became a hybrid: a godlike human. In the Gospel of Mark, Jesus says, ‘Abba, Father.’ (Mark 14:36) More than a decade before Mark, Paul used that particular phrasing twice (Romans 8:15, Galatians 4:6). You read Paul’s words in the Gospel of Mark, just like at the Last Supper. Also, ‘The Twelve’ is a quote you can trace back to Paul. Likely, there were no twelve disciples. It took Paul over a decade to work out his new theology, and perhaps countless sleepless nights as well.

Around 55 AD, Paul wrote that the woman came from man (1 Corinthians 11:7-8), thereby reasserting the biblical account from Genesis rather than the original Christian account, of which we can still find traces in the Gospel of John. In Galatians, Paul also writes that God sent His Son, who was born of a woman (Galatians 4:4). That Jesus was born of a woman is stating the obvious. You don’t need to stress that, even when God is Jesus’ Father. If God were a Father, this factoid could be among the most uninteresting disclosures in the entire letter. The original Christian teaching, which Paul tried to obfuscate, was that Jesus was Adam reincarnated, so he was born of God. Paul claimed that Jesus is the Son of God the Father and was not Adam. And so, he was born of a woman rather than God. For once, Paul didn’t lie by stressing that particular factoid. It is also noteworthy that he didn’t write ‘born of a virgin.’ Had he known about the virgin birth, it would have been worth mentioning. By 55 AD, no one still knew about it.

For religious Jews, it was blasphemy to say that God was a woman who married Jesus. So it was probably also problematic for many Jewish converts, while non-Jewish converts had no issues with it. The Greek and Roman traditions had several gods and goddesses who had children with humans. For the Greeks and the Romans, God being a woman marrying a man who lives eternally is not that spectacular, while it is unthinkable for Jews. That made uniting the early Church an enormous challenge. To Paul, a former Pharisee, the truth of the scriptures mattered more than the facts. He could dismiss the Christian creation story and change God’s gender. Not having been a firsthand witness and not having spoken much to the other Apostles for the first fourteen years further helped him maintain his independent and particular perspective.

And the facts created challenges that Paul’s fantasy theology would solve. In the first epistle to the Corinthians, Paul writes, ‘It is reported that there is sexual immorality among you, and of a kind that even pagans don’t tolerate: A man is sleeping with his father’s wife. And you are proud!’ (1 Corinthians 5:1-2). Possibly, a scribe watered down this controversial fragment during copying, or it was so scandalous that Paul himself chose to formulate the truth in this fashion. The man might have slept with his mother, or probably did. After all, it is sexual immorality that even pagans don’t tolerate. And the Christians in Corinth took pride in it. Perhaps they believed this man followed Christ’s example.

Paul’s unique advantage, which placed him in the position to shape Christian theology, was that, apart from being an educated scholar with a dedication to the scriptures, he was not a firsthand witness to the events. To him, reality had to fit the scriptures rather than the other way around. He never met Mary Magdalene and Jesus, and didn’t meet with the other Apostles during the first years of his preaching. That allowed him to develop his theology independently of the facts.

As a Jew preaching among the Gentiles, he could bridge the gap between the Jewish and the Gentile views. His theology appealed to Jewish Christians because it connected Christianity to the Jewish scriptures and portrayed Jesus as the Jewish Messiah. At the same time, his preaching tours and letter writing provided him with a support base among the Gentile Christians as well, who saw Jesus as godlike. Pauline theology also shares that view. God the Father became the compromise between Yahweh and the Mother.

Paul’s diligent labour provided Christianity with an elaborate theological foundation, and his view could also bring unity within the early Church, so it prevailed. Most people only knew Jesus from stories, and few knew the details, so it was possible to sway opinions with false stories. It is still possible today, even when everyone can check the facts. The outcome of Paul’s intervention was that Christianity became an entirely different religion. Had a close follower of Jesus from 30 AD accidentally run into a time portal and leapt into the future, he wouldn’t have recognised his religion already in 100 AD, let alone today.

Spreading the good news

Paul dedicated his life to spreading the good news that faith in Jesus could save everyone. During his many travels, he founded Christian communities. His mission wasn’t easy. His message caused upheaval, and Jews expelled him from their synagogues several times. But he was determined and worked hard. Paul’s gospel of personal salvation through faith in Jesus Christ, which is open to everyone, appears to have caught on. However, it is a most peculiar tidings and not something you would believe if you had grown up in a different tradition, whether you were Jewish or worshipped other deities. And so the success of Christianity begs for a better explanation. Ancient sources indicate that stories about the miracles Christians performed made people convert.¹ An example was the healing of a lame man when Paul and Barnabas visited Lystra.

We have to take Paul’s word for it, as he is a likely source. Had we not known Paul as a fantasist, it appears plausible. In other words, it might have happened. In other words, it might have happened. As the story says, Paul had healed the man. The Lycaonians then concluded Paul and Barnabas were gods in human form. The priest of Zeus brought bulls and wreaths to the city gate, as he and the crowd wished to offer sacrifices to them. Paul and Barnabas explained that they were only human and messengers of the good news that the God of the Jews, who had made the heavens, the earth, the sea, and everything in them, had decided that all nations should no longer go their own way. And the proof, they said, was that the Jewish God had shown kindness by giving us rain from heaven and crops in their seasons and filling our hearts with joy (Acts 14:8-18). The proof thus was the seasons, the crops and the rains, and, of course, joy in our hearts. The seasons and the crops had always been there, and people had been joyful before, so that didn’t prove much. Hence, it must have been the miracle of healing that made people believe Paul’s unusual message.

Paul’s activities led to a riot in the city of Ephesus. Demetrius, who made silver shrines of the goddess Artemis and brought in a lot of trade for the local businesspeople, realised the consequences of Paul’s good tidings. He called the craftsmen and workers in related occupations together and said, ‘You know, my friends, we receive a good income from this business. And you see and hear how this fellow Paul has convinced and led astray many people here in Ephesus and in practically the whole province of Asia. He says that gods made by human hands are no gods at all. There is danger not only that our trade will lose its good name but also that the temple of the great goddess Artemis will be discredited and that the goddess herself will be robbed of her divine majesty.’ When they heard this, they were furious and began shouting, ‘Great is Artemis of the Ephesians!’ Soon, the whole city was in an uproar (Acts 19:23-29). A mob seized Gaius and Aristarchus, Paul’s travelling companions from Macedonia, and brought them to an assembly in a theatre.

A city clerk managed to quiet the crowd in the theatre. He said, ‘Fellow Ephesians, doesn’t the world know that the city of Ephesus is the guardian of the temple of Artemis and of her image, which fell from heaven? Since these facts are undeniable, you should calm down and not do anything rash. You have brought these men here, though they have neither robbed temples nor blasphemed our goddess. If Demetrius and his fellow craftsmen have a grievance against anybody, the courts are open, and there are proconsuls. They can press charges. If there is anything further you want to bring up, it must be settled in a legal assembly. As it is, we are in danger of being charged with rioting because of what happened today. In that case, we would not be able to account for this commotion since there is no reason for it.’ After he had said this, he dismissed the assembly (Acts 19:35-41). Had it been untrue, then the spread of Christianity would have become a bit harder to explain, but not impossible. More upheavals were to come in the following centuries.

Contending versions of Christianity

During the first centuries, there were several versions of Christianity. It highlights contentious issues, suggesting that early Christian beliefs differ from those of Christianity today. Christianity today is not what it originally was. The alternative views are likely closer to the original faith in some respects because they reflect earlier beliefs. The most well-known deviant groups were the Nazarenes, the Marcionists, the Ebionites, and the Arians:

• The Nazarenes continued to observe the Jewish religious laws. Jesus didn’t intend to abolish them. It was Paul who came up with that idea.
• The Marcionists taught that the God of the Gospel is the true Supreme Being as opposed to the evil Jewish God. Indeed, God is not the deity the Jews imagined.
• The Ebionites didn’t believe that Jesus was divine, nor did they think that he was born of a virgin. That is also correct.
• Arianism emerged around 300 AD. The Arians opposed the doctrine of the Trinity, which was not an original Christian teaching.

Except for the Arians, these groups existed from an early period. Christianity was in flux. That began to change once the Roman Emperor Constantine made Christianity the state religion of the Roman Empire. Constantine invited all the bishops in the Roman Empire to the First Council of Nicaea in 325 AD. It was the first effort to create a uniform Christian doctrine. More efforts followed. The Roman state promoted the Church’s official teachings. Consequently, other strains of Christianity faded into obscurity.

The Gospels of the New Testament date from 70 to 100 AD, more than forty years after Jesus preached. Mark, Luke, Matthew, and John did not write the Gospels attributed to them. The Apostles were uneducated, Aramaic-speaking Jews, while the authors were educated, Greek-speaking Christians who were not eyewitnesses. Scholars believe Mark, Luke, and Matthew are collections of stories that circulated among early Christians. The author of the Gospel of Luke even says so (Luke 1:1-4).

Whenever someone retells a story, details change, new episodes emerge, and parts get omitted. And the story may become more spectacular. And so, the Gospels likely don’t accurately tell what happened. Several letters in the New Testament are anonymous, despite claiming to be from Peter, Paul, or another well-known figure. Jesus’ brother couldn’t have been the author of the Epistle of James because it contains no inside knowledge about the relationship between God and Jesus. And we don’t have the original texts of the New Testament. The oldest preserved copies date back to the second or third centuries AD. Scholars have used these copies to reconstruct the original texts as much as possible.
