So that none should imagine God the Father to be other than our Creator, as the heretics imagine; (for) they despise the God who is, and make gods of that which is not; and they fashion a Father of their own above our Creator, and imagine that they have found out for themselves something greater than the truth. For all these are impious and blasphemers against their Creator and against the Father, as we have shown in the Exposure and Overthrow of Knowledge falsely so-called. And others again reject the coming of the Son of God and the dispensation of His incarnation, which the apostles delivered and the prophets declared beforehand, even such as should be the summing up of mankind, as we have shown you in brief: and such also are reckoned amongst those who are lacking in faith. And others receive not the gifts of the Holy Spirit, and cast away from themselves the prophetic grace, [301] watered whereby man bears the fruit of life unto God: and these are they of whom Isaiah speaks:

For they shall be, saith he, as an oak that is stripped of leaves, and as a garden that hath no water. And such are in no wise serviceable to God, seeing that they cannot bear any fruit.
