Our starting-point must be the fact that God cannot be named... no mind has yet contained or language embraced God's substance in its fullness. No, we use facts connected with Him to outline qualities that correspond with Him, collecting a faint and feeble mental image from various quarters. Our noblest theologian is not one who has discovered the whole - our earthly shackles do not permit us the whole - but one whose mental image is by comparison fuller, who has gathered in his mind a richer picture, outline, or whatever we call it, of the truth.
Gregory of NazianzusThe Godhead is, to speak concisely, undivided there is one mingling of Light, as it were of three suns joined to each other.
Gregory of NazianzusThese three things God requires of all the Baptized: right faith in the heart, truth on the tongue, temperance in the body.
Gregory of NazianzusIt is difficult to practice obedience; but it is even more difficult to practice leadership.
Gregory of NazianzusNo one seeing a beautifully elaborated lyre with its harmonious, orderly arrangement, and hearing the lyre's music will fail to form a notion of its craftsman-player, to recur to him in thought though ignorant of him by sight. In this way the creative power, which moves and safeguards its objects, is clear to us, though it be not grasped by the understanding. Anyone who refuses to progress this far in following instinctive proofs must be wanting in judgment. But still, whatever we imagined or figured to ourselves or reason delineated is not the reality of God.
Gregory of NazianzusIt is more important that we should remember God than that we should breathe: indeed, if one may say so, we should do nothing else besides.
Gregory of NazianzusIf our Lord ascends up to Heaven, ascend with Him. Be one of those angels who escort Him, or one of those who receive Him. Bid the gates be lifted up (cf. Ps. 24:7, 10), or be made higher, that they may receive Him, exalted after His Passion. Answer to those who are in doubt because He bears up with Him His body and the tokens of His Passion, which He had not when He came down, and who therefore inquire, 'Who is this King of Glory?' that it is the Lord strong and mighty, as in all things that He has done from time to time and does, so now in His battle and triumph for the sake of Mankind.
