Understanding the Scriptures
The Didache is the first known Christian catechesis. Written in the first century, the didache is the earliest known Christian writing outside of Scripture. The name of the work, "Didache", is indeed appropriate for such a catechesis because i comes from the greek word for "teaching" and indicates that this writing contains the teaching of the Apostles. The Didache is a catechetical summary of Christian Sacraments, practices and morality. Though written in the first century, its teaching is timeless. The Didache was probably written by the disciples of the Twelve Apostles, and it presents the Apostolic Faith as taught by those closest to Jesus Christ.
