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 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 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 NazianzusWe are not made for ourselves alone, we are made for the good of all our fellow creatures.
Gregory of Nazianzus...a disposition is an unsatisfactory thing unless we give it practical effect - deeds show dispositions.
Gregory of Nazianzus...though every thinking being longs for God, the First Cause, it is powerless... to grasp Him. Tired with the yearning it chafes at the bit and, careless of the cost, it tries a second tack. Either it looks at things visible and makes of these a god - a gross mistake, for what visible thing is more sublime, more godlike, than its observer... - or else it discovers God through the beauty and order of things seen, using sight as a guide to what transcends sight without losing God through the grandeur of what it sees.
