Moving into the future after schisms meant that each church made a lot of unexpected twists and turns. Take the Lord’s Prayer. Jesus taught it in the Bible. A late 1st century writing added a doxology (“for yours is the power and the glory forever”). The late 4th century added “the kingdom.” Catholics took their version from the one preferred by Henry the VIII in 1545 with no doxology. We, perhaps, took ours from a Protestant Reformer, Martin Bucer, who used it in a liturgy he wrote in 1539. So, to get to us today, the Lord’s Prayer went from Capernaum, to Egypt, to Syria, to England, to Strasbourg to Scotland to America. That is no short trip!1
