As we come to a close, I think it’s important to recap everything so far.
Your initial argument was that scripture displays characteristics that are likely best explained by divine inspiration, rather than the product of humans. Since it is divinely inspired, the Christian god must exist to have been the one to inspire it.
I spent the next several rounds dismantling the notion that the Bible is inerrant. We agree it is full of misaligned stories, scribal errors, added interpolation by human hands, and mistranslations. This directly refutes your initial argument for gods existence.
You are correct that I mentioned the resurrection, but within a statement I was making about the later alterations added to Mark. I was still arguing to disprove your claim that scripture is inerrant.
However you are correct that my previous statement about Mark’s long ending being a “5th century fabrication” is false. It developed over time during the 2nd and 3rd century. That still does not support your claim that scripture is gods inspired word.
After that, you began using the resurrection to argue for God’s existence. Since you admitted errors in the Bible, and changed which argument you were using, I believe that concedes your first point about biblical inerrancy.
You are correct that I have not made any positive claims giving any naturalistic explanations for the beginning of Christianity. Since you are the one making a positive claim about God existing, I didn’t feel it was necessary. But I will correct that here.
Given all the possible explanations for Jesus’ body missing, and people claiming to have seen him after his death, bodily resurrection is quite literally the least likely of them all. You have to remember that Jesus was an apocalyptic preacher. He preached about salvation and the end times in an extremely tense political and religious climate. Couple a charismatic, apocalyptic leader with the high amounts of superstition and lower understanding of how the world actually works, and you get a radical movement that spreads quickly. Not only that, but Jesus claimed he would come back from the dead. So the radical expectation of resurrection was already given to his followers. Grave robbery is the most likely explanation for the empty tomb, as it was very common back then. Mysticism was very popular, and the body parts of a “miracle working rabbi” would have been worth a lot. Some of his followers may have had hallucinations, but the post resurrection stories are likely entirely made up through early Christian doctrine.
Now, you are correct about 1 Corinthians being a very early document claiming the resurrection and divinity of Jesus. But early doesn’t mean true. Paul’s claims are entirely baseless. He says Jesus appeared to 500 people that are still alive, and didn’t name a single one. No court of law would take that seriously.
All throughout history, religious zealots, and cult members have happily gone to death for what they believed to be true. Reality is that sincerity of someone’s beliefs does not make them true.
As for the long-term success of Christianity, this can be greatly attributed to emperor Theodosius when he mandated Christianity as the official state religion of Rome. His motivation for this is quite simple. He ruled one of the largest empires in human history, spanning multiple continents and countless people groups/cultures. What better way to unite his empire than to make everyone believe in a single God, and then use God to justify his rule?
In conclusion, the Bible is clearly a human orchestrated document with several inconsistencies, errors, mistranslations, and later interpolations. Because of this, scripture, which contains the only historical accounts of Jesus resurrecting from the dead, cannot be considered an accurate historical document without any contemporary, corroborating evidence.
The early Christian movement likely gained so much traction due to the combination of a charismatic apocalyptic leader that promised victory and a better life for an oppressed people, and the grief, hysteria, and delusion that followed after the death of their beloved leader.
Christianity was then used by leaders and politicians for millennia to come as a tool for building society.
Without the inerrancy of scripture, and strong evidence to believe in the resurrection, there is nothing pointing to the existence of the Christian God.
I’m very thankful for my opponent, who argued in good faith and was very respectful throughout this conversation. I wish him nothing but the best. Sincerely.
