Quotes from the same author

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.
 Tertullian
In our case, murder being once for all forbidden, we may not destroy even the foetus in the womb, while as yet the human being derives blood from other parts of the body for its sustenance. To hinder a birth is merely a speedier mankilling; nor does it matter whether you take away a life that is born, or destroy one that is coming to the birth. That is a man which is going to be one; you have the fruit already in the seed.
 Tertullian
He is a man, who is to be a man; the fruit is always present in the seed.
 Tertullian
I believe because it is absurd.
 Tertullian
The Son of God died; it is by all means to be believed because it is absurd. And he was buried and rose again; the fact is certain, because it is impossible.
