Thus 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.
TertullianFor what war should we not be fit and eager, even though unequal in numbers, we who are so willing to be slaughtered-if, according to that discipline of ours, it was not more lawful to be slain than to slay?
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
