As 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 NazianzusDo you conceive of your Lord as less because? He shows that humiliation is the best road to exaltation (cf. Mt. 23:12); because He humbles Himself for the sake of the soul that is bent down to the ground, that He may even exalt within Himself that which is bent double under a weight of sin?... If so, you must blame the physician for stooping over suffering and putting up with evil smells in order to give health to the sick?
Gregory of NazianzusWho should listen to discussions of theology? Those for whom it is a serious undertaking, not just another subject like any other for entertaining small-talk, after the races, the theater, songs, food, and sex: for there are people who count chatter on theology and clever deployment of arguments as one of their amusements.
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 NazianzusNo one has yet discovered or ever shall discover what God is in His nature and essence... we shall, in time to come, 'know as we are known' (I Cor 13:12). But for the present what reaches us is a scant emanation, as it were a small beam from a great light - which means that any one who 'knew' God or whose 'knowledge' of Him has been attested to in the Bible, has a manifestly more brilliant knowledge than others not equally illuminated. This superiority was reckoned knowledge in the full sense, not because it really was so, but by the contrast of relative strengths.
Gregory of NazianzusLet us become like Christ, since Christ became like us. He assumed the worse that He might give us the better; He became poor that we through His poverty might be rich.
Gregory of NazianzusWhen one has looked upon Jesus, though he be of little stature like Zacchaeus of old (cf. Lk. 19:3), and climb up on the top of the sycamore tree by mortifying his members which are upon the earth (cf. Col. 3:5), and having risen above the body of humiliation, then he shall receive the Word, and it shall be said to him, This day has salvation come to this house (cf. Lk. 19:9). Then let him lay hold on the salvation, and bring forth fruit more perfectly, scattering and pouring forth rightly that which as a publican he wrongly gathered.
