If time came before me, time is not before the Word, whose Begetter is atemporal. When the beginningless Father was there, leaving nothing superior to His divinity, then also was there the Father's Son, having in the Father a timeless beginning, like the sun's great circle of overwhelming clear light.
Gregory of NazianzusIf anyone does not believe that Holy Mary is the Mother of God, such a one is a stranger to the Godhead.
Gregory of NazianzusHow is it... that the Son and Holy Spirit are not co-unoriginate with the Father, if they are co-eternal with Him? Because they are from Him, though not after Him. 'Being unoriginate' necessarily implies 'being eternal,' but 'being eternal' does not entail 'being unoriginate,' so long as the Father is referred to as origin. So because They have a cause They are not unoriginate... a cause is not necessarily prior to its effects... Because time is not involved, They are to that extent unoriginate... for the sources of time are not subject to time.
Gregory of NazianzusAs far as we can reach, He Who Is, and God, are the special names of His Essence; and of these especially He Who Is, not only because when He spoke to Moses in the mount, and Moses asked what His Name was, this was what He called Himself, bidding him say to the people 'I Am has sent me' (Ex. 3:14), but also because we find that this Name is the more strictly appropriate.
Gregory of NazianzusThere is One God and One Mediator between God and man, the man Jesus Christ (cf. I Tim. 2:5). For He still pleads even now as man for my salvation; for He continues to wear the Body which He assumed, until He make me a god by the power of His Incarnation; although He is no longer known after the flesh (cf. II Cor. 5:16) ? I mean, the passions of the flesh, the same, except sin, as ours.
