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.
TertullianExamine then, and see if He be not the dispenser of kingdoms, who is Lord at once of the world which is ruled, and of man himself who rules; if He have not ordained the changes of dynasties, with their appointed seasons, who was before all time, and made the world a body of times; if the rise and the fall of states are not the work of Him, under whose sovereignty the human race once existed without states at all.
Tertullian
