Now then, you dogs, whom the apostle puts outside and who yelp at the God of truth, let us come to your various questions.
TertullianThe 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.
TertullianThus the connection of the Father in the Son, and of the Son in the Paraclete, produces three coherent Persons, who are yet distinct One from Another. These three are one [thing], not one [Person], as it is said, 'I and my Father are One,' in respect of unity of substance not singularity of number.
