As early as the middle of the first century, a treatise known as the Didache began to be circulated. The word means “teaching.” Attested in some manuscripts as the teaching of the twelve apostles, it is absolutely the teaching of an early Jewish Christian community who had compiled the work over decades on the basis of a preexisting Jewish catechetical text which spoke about “the Two Ways” for it’s opening lines, “there are two ways: one of life and one of death. There are great differences between these two ways.”
