Tertullian — Prescription against Heretics 13

Now, with regard to this rule of faith — that we may from this point acknowledge what it is which we defend — it is, you must know , that which prescribes the belief that there is one only God , and that He is none other than the Creator of the world, who produced all things out of nothing through His own Word, first of all sent forth; that this Word is called His Son, and , under the name of God , was seen in diverse manners by the patriarchs, heard at all times in the prophets , at last brought down by the Spirit and Power of the Father into the Virgin Mary , was made flesh in her womb, and, being born of her, went forth as Jesus Christ ; thenceforth He preached the new law and the new promise of the kingdom of heaven , worked miracles ; having been crucified, He rose again the third day; (then) having ascended into the heavens, He sat at the right hand of the Father; sent instead of Himself the Power of the Holy Ghost to lead such as believe ; will come with glory to take the saints to the enjoyment of everlasting life and of the heavenly promises, and to condemn the wicked to everlasting fire , after the resurrection of both these classes shall have happened, together with the restoration of their flesh.

This rule, as it will be proved , was taught by Christ, and raises among ourselves no other questions than those which heresies introduce, and which make men heretics .
