No 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 NazianzusWhat is the right time [to discuss theology]? Whenever we are free from the mire and noise without, and our commanding faculty is not confused by illusory, wandering images, leading us, as it were, to mix fine script with ugly scrawling, or sweet-smelling scent with slime. We need actually 'to be still' (Ps. 46:10) in order to know God, and when we receive the opportunity, 'to judge uprightly' (Ps. 75:2) in theology.
Gregory of NazianzusBut as the old Confusion of tongues was laudable, when men who were of one language in wickedness and impiety, even as some now venture to be, were building the Tower; for by the confusion of their language the unity of their intention was broken up, and their undertaking destroyed; so much more worthy of praise is the present miraculous one. For being poured from One Spirit upon many men, it brings them again into harmony. And there is a diversity of Gifts, which stands in need of yet another Gift to discern which is the best, where all are praiseworthy.
Gregory of NazianzusWe are not made for ourselves alone, we are made for the good of all our fellow creatures.
Gregory of NazianzusWhat He was, He laid aside; what He was not, He assumed. He takes upon Himself the poverty of my flesh so that I may receive the riches of His divinity.
Gregory of NazianzusIf 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 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.
