There was an apostasy I will agree. It is my opinion that the true Christians were raptured into heaven long, long ago. This occurrence caused the Roman empire to create its own church, called the Roman Catholic Church. An empire who went from killing Christians to claiming to be one, whose empire fell but the church lived on. I find it really strange how the story of Paul who claims to be the 13th apostle who once himself judged and captured Christians to bring them to their death then claims to have become one and becomes the leader, the apostle sent to the gentiles because the Jews had rejected Christ. I believe this story was made up and that Paul is actually the Roman Catholic Church. The writer intentionally did this to give hints of the truth to future generations which was at that time greatly suppressed. It is strange how the Catholic church doesn’t even recognize Paul, but rather claims that Peter was the first Pope of the Roman Catholic Church.
After the creation of the Roman Catholic church, Mohammed (peace be upon him) shows up on the scene who I believe was a true prophet, he warns us about the coming Anti-Christ.
The Roman Catholic church waged war with the followers of Mohammed, while Christian history tries to teach it the other way around. The Roman Catholic Church had torture chambers that surpass anything since, and many Muslims and Jews were tortured to death.
After the Anti-Christ rules the world for a bit, then Jesus (peace be upon him) will return along with the true Christians who were raptured long, long ago. He will set up his kingdom on earth as it is in heaven.
