Almost every sin is committed for the sake of sensual pleasure; and sensual pleasure is overcome by hardship and distress arising either voluntarily from repentance, or else involuntarily as a result of some salutary and providential reversal. 'For if we would judge ourselves, we should not be judged; but when we are judged, we are chastened by the Lord, so that we should not be condemned with the world.' (1 Cor. 11:31-32).
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.
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.
