Offerings to propitiate the dead then were regarded as belonging to the class of funeral sacrifices, and these are idolatry. Idolatry, in fact, is a sort of homage to the departed, the one as well as the other is a service to dead men. Moreover, demons dwell in the images of the dead. ... this sort of exhibition has passed from honors of the dead to honors of the living; I mean, to quaestorships [financial overseers]and magistractes, to priestly offices of different kinds. Yet, since idolatry still cleaves to the dignity's name, whatever is done in its name partakes of its impurity.
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.
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.
TertullianI owe no duty to the forum, the election ground or the senate; I am ... no barking pleader, no judge, no soldier, no king; I have withdrawn from the populace. My only business is with myself. I have no care save not to care. The better life you would more enjoy in seclusion than in publicity. But you will decry me as indolent. ... None is born for another, being destined to die for himself.
TertullianIf we refuse our homage to statues and frigid images, the very counterpart of their dead originals, with which hawks, and mice, and spiders are so well acquainted, does it not merit praise instead of penalty [Christians were punished for not worshiping Roman gods] that we have rejected what we have come to see is error? We cannot surely be made out to injure those whom we are certain are nonentities. What does not exist is in its nonexistence secure from suffering.
