We just learned about the Didache - The Teaching of the Twelve Apostles.
Another part of early Christian history is the book Against Heresies, by Irenaeus.
During the early time of Christianity when people disagreed about what they should believe, there was a group of people called the Gnostics.
They believed that Christ and Jesus were two separate beings.
Like Jesus was a physical body, and Christ was a spirit that lived in him.
The bishop of France named Irenaeus was very upset about this, and decided to write a book saying why they were wrong.
His book was written some time around 180 AD, and many church leaders used that letter to tell people that they believed Gnosticism was not true.
