The Law found more than it lost when Christ said, โLove your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heavenโ (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.
TertullianHe has inhibited discussion by designating admonition as the method of dealing with a heretic- and the first method, too, because he is not a Christian. This is so that he would not seem to require correction again and again and before two or three witnesses as though he were a Christian. He ought to be corrected for the very reason that he is not to be disputed with. In addition, this is said because a controversy over the Scriptures can, clearly, produce no other effect than help to upset either the stomach or the brain.
