Yes, "Here endeth the lesson" is a traditional wrap-up phrase after a Bible reading in church, especially from the King James version. It was common up until about the 1950s, and probably in several different denominations, but it has gradually been eliminated because it sounds so dated, particularly after a passage from a more modern translation.
However, it is still specified as the wording after the Bible reading in one form of Anglican service, according to the web page below which is an online copy of part of their "Book of Common Order".
Bible readings in our church end with this:
(Reader) This is the word of the Lord.
(All respond) Thanks be to God.
