The baptism
Go ye and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost. He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
1 Cor. 11, 23f
So much is sufficient for a simple person to know from the Scriptures concerning Baptism. In like manner, also, concerning the other Sacrament, in short, simple words, namely, the text of St. Paul 1 Cor. 11, 23f.
