I 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 NazianzusGod always was, and always is, and always will be. Or rather, God always Is. For Was and Will be are fragments of our time, and of changeable nature, but He is Eternal Being. And this is the Name that He gives to Himself when giving the Oracle to Moses in the Mount. For in Himself He sums up and contains all Being, having neither beginning in the past nor end in the future; like some great Sea of Being, limitless and unbounded, transcending all conception of time and nature, only adumbrated [intimated] by the mind, and that very dimly and scantily.
Gregory of Nazianzus...God will be 'all in all' (I Cor. 15:28) when we are no longer what we are now, a multiplicity of impulses and emotions, with little or nothing of God in us, but are fully like God , with room for God and God alone. This is the 'maturity' (cf. Col. 1:28) towards which we speed.
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.
