Does the Bible suggest that there would be a literal apostasy of the early Christian church?

In 2 Thessalonians 2:3 and Acts 20:29 I interpret them to mean that there would be a literal apostasy of the early Christian church or is there another meaning to them that I am missing? >2 Thessalonians 2:3: Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; > > Acts 20:29: For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
