When we are going to enter the water ... in the presence of the congregation and under the hand of the president, we solemnly profess that we disown the devil, his pomp, and his angels. After this we are immersed three times, making a somewhat larger pledge than the Lord appointed in the Gospel. Then we are taken up [a reference to the Roman tradition of recognizing a newborn baby as a member of the family]. We first taste a mixture of milk and honey and from that day we refrain from the daily bath for a whole week.
TertullianWhat is nobler than to tread under foot the gods of the nations, to exorcise evil spirits, to perform cures, to seek divine revelations, and to live to God? These are the pleasures - these are the spectacles - that befit Christian men.
Tertullian
