Who gave you the ability to contemplate the beauty of the skies, the course of the sun, the round moon, the millions of stars, the harmony and rhythm that issue from the world as from a lyre, the return of the seasons, the alternation of the months, the demarcation of day and night, the fruits of the earth, the vastness of the air, the ceaseless motion of the waves, the sound of the wind?
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 NazianzusCan 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 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.
