How 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 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.
Gregory of NazianzusThe Godhead is, to speak concisely, undivided there is one mingling of Light, as it were of three suns joined to each other.
Gregory of NazianzusAll who have lived according to God still live unto God, though they have departed this life. For this reason, God is called the God of Abraham, Isaac and Jacob, since He is the God, not of the dead, but of the living
Gregory of NazianzusMay God preserve me from being rich while they are indigent, from enjoying robust health if I do not try to cure their diseases, from eating good food, clothing myself well and resting in my home if I do not share with them a piece of my bread and give them, in the measure of my abilities, part of my clothes and if I do not welcome them into my home
