Keep always in mind the rule of faith which I profess and by which I bear witness that the Father and the Son and the Spirit are inseparable from each other, and then you will understand what is meant by it. Observe now that I say the Father is other [distinct], the Son is other, and the Spirit is other. This statement is wrongly understood by every uneducated or perversely disposed individual, as if it meant diversity and implied by that diversity a separation of Father, Son, and Holy Spirit
TertullianIn 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.
TertullianI revere the fullness of His Scripture, in which He manifests to me both the Creator and creation. In the gospel moreover, I discover a Minister and Witness of the Creator, even His Word.
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.
Tertullian
