An early ‘Church Order’, professedly the ‘Catholic Teaching of the Twelve Apostles … of our Redeemer’. It is addressed to readers in various states of life and deals with miscellaneous subjects, such as penance, liturgical worship, and behaviour during persecution, but the arrangement is disorderly. It is directed especially against Christians who regard the Jewish ceremonial law as still binding. It seems to have been composed in N. Syria in the 3rd cent. Written in Greek, it survives entire only in a Syriac version.
