The Law found more than it lost when Christ said, ‘Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven’ (Matthew 5:44-45). This most important commandment summarizes in a word the universal discipline of patience, since it does not allow us to do evil even to people who deserve it.
TertullianWhen 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.
