What 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 NazianzusSuch is the grace and power of baptism; not an overwhelming of the world as of old, but a purification of the sins of each individual, and a complete cleansing from all the bruises and stains of sin. And since we are double-made, I mean of body and soul, and the one part is visible, the other invisible, so the cleansing also is twofold, by water and the Spirit; the one received visibly in the body, the other concurring with it invisibly and apart from the body; the one typical, the other real and cleansing the depths.
Gregory of NazianzusMay God preserve me from being rich while they are indigent, from enjoying robust health if I do not try to cure their diseases, from eating good food, clothing myself well and resting in my home if I do not share with them a piece of my bread and give them, in the measure of my abilities, part of my clothes and if I do not welcome them into my home
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 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.
