31. Therefore it will be much more accurate to denote God from the Son and to call Him Father, than to name Him and call Him Unoriginated from His works only; for the latter term refers to the works that have come to be at the will of God through the Word, but the name of Father points out the proper offspring from His essence. And whereas the Word surpasses things originated, by so much and more also doth calling God Father surpass the calling Him Unoriginated; for the latter is non-scriptural and suspicious, as it has various senses; but the former is simple and scriptural, and more accurate, and alone implies the Son. And ‘Unoriginated’ is a word of the Greeks who know not the Son: but ‘Father’ has been acknowledged and vouchsafed by our Lord; for He knowing Himself whose Son He was, said, ‘I in the Father and the Father in Me;’ and, ‘He that hath seen Me hath seen the Father;’ and, ‘I and the Father are one;’ but nowhere is He found to call the Father Unoriginated. Moreover, when He teaches us to pray, He says not, ‘When ye pray, say, O God Unoriginated,’ but rather, ‘When ye pray, say, Our Father, which art in heaven.’ And it was His Will, that the Summary of our faith should have the same bearing. For He has bid us be baptized, not in the name of Unoriginate and Originate, not into the name of Uncreate and Creature, but into the name of Father, Son, and Holy Spirit, for with such an initiation we too are made sons verily, and using the name of the Father, we acknowledge from that name the Word in the Father. But if He wills that we should call His own Father our Father, we must not on that account measure ourselves with the Son according to nature, for it is because of the Son that the Father is so called by us; for since the Word bore our body and came to be in us, therefore by reason of the Word in us, is God called our Father. For the Spirit of the Word in us names through us His own Father as ours, which is the Apostle’s meaning when he says, ‘God hath sent forth the Spirit of His Son into your hearts, crying, Abba, Father.’
