The Teaching of the Twelve Apostles
Chapter 7: Concerning Baptism
And concerning baptism, baptize in this way: After you have first said all these things, baptize in the name of the Father, and of the Son, and of the Holy Spirit, Matthew 28:19, in living water. But if you do not have living water, baptize in other water. And if you cannot do it in cold water, then do it in warm. But if you have neither, pour out water three times on the head in the name of the Father and Son and Holy Spirit. But before the baptism, let the one who baptizes fast, and the one being baptized, and any others who can. And you shall instruct the one being baptized to fast one or two days beforehand.
