If the subject of the resurrection of Jesus Christ were to be argued by academics, researching professors and the like. The number one theory that atheists would claim against the resurrection is the Constantine Conspiracy. This is how the Constantine theory works. The earliest Christians, and the first followers never believed him to be God. They though he was just a great teacher. Its not until the fourth Century that Jesus is turned into a god. Supposedly when the Roman Emperor Constantine [1] became a Christian he decided to deify Christ, and this is how we have the Jesus we know today.
I decided to write on this theory because when you take an informed look at the theory it becomes so ridiculous that it really is funny. Lets see what had to happen for this conspiracy theory to be true. First we have nearly 6,000 full and partial Greek manuscripts [2] of the New Testament from before Constantine was alive. So now Constantine and his supporters have to find many times 6,000 manuscripts, change them to say that Jesus rose from the dead, don't get caught, and they can't show their ink work. Now, do you honestly think that the new testament hadn't been translated by the fourth century? There was by this time New Testament translations in Latin, Syriac, and Coptic [3]. So now our conspirators need to find many times 6,000 Greek manuscripts, all the Latin, Coptic, and Syriac translations, change them to say Jesus is God, and rose from the dead, don't get caught and don't show their ink work.
It gets better. We have so many written quotations of the Bible by early church fathers that we can recreate over 95% of the New Testament with quotations alone. Lets go over what has to happen now. Our conspirators have to find many times 6,000 manuscripts, don't get caught, don't show their ink work, and never tell anyone. Next they need to find all the Latin, Syriac, and Coptic translations, don't get caught, don't show their ink work, and never tell anyone. Then they need to find all the writings of the early church fathers, change them to say that Jesus is a god and rose from the dead, don't get caught, don't show their ink work, and never tell anyone. Not even the Justice League [4] could pull that off! This is a ridiculous theory.
