Can anyone be a father without beginning to be one? Yes, one who did not begin his existence. What begins to exist begins to be a father - God the Father did not begin at all. He is Father in the true sense, because He is not a son as well. Just as the Son is son in the true sense, because He is not a father as well. In our case, the word 'father' cannot be truly appropriate, because we must be fathers and sons.
Gregory of NazianzusIt is like employing a small tool on big constructions, if we use human wisdom in the hunt for knowledge of reality.
Gregory of NazianzusLet us quake before the great Spirit, Who is my God, Who has made me know God, Who is God there above, and Who forms God here: almighty, imparting manifold gifts, Him Whom the holy choir hymns, Who brings life to those in heaven and on earth, and is enthroned on high, coming from the Father, the divine force, self-commandeered; He is not a Child (for there is one worthy Child of the One who is best), nor is He outside the unseen Godhead, but of identical honor.
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 NazianzusMay you be children of God, pure and unblameable, in the midst of a crooked and perverse generation (cf. Phil. 1:15): and may you never be entangled in the snares of the wicked that go round about, or bound with the chains of your sins. May the Word in you never be smothered with the cares of this life and so make you unfruitful: but may you walk in the King's Highway, turning aside neither to the right hand nor to the left, but led by the Spirit through the narrow gate.
Gregory of NazianzusI cannot think on the one without quickly being encircled by the splendor of the three; nor can I discern the three without being straightway carried back to the one.
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.
