The Word, then, the Christ, is the cause both of our ancient beginning, for lie was in God, and of our well-being. And now this same Word has appeared as man. He alone is both God and man, and the source of all our good things
TertullianWe say, and we say openly, and while ye torture us, mangled and gory we cry out, "We worship God through Christ!" Believe Him a man: it is through Him and in Him that God willeth Himself to be known and worshipped.
TertullianIndeed it is better to postpone, lest either we complete too little by hurrying, or wander too long in completing it.
TertullianKeep 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
