All who have lived according to God still live unto God, though they have departed this life. For this reason, God is called the God of Abraham, Isaac and Jacob, since He is the God, not of the dead, but of the living
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 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 NazianzusThese three things God requires of all the Baptized: right faith in the heart, truth on the tongue, temperance in the body.
Gregory of NazianzusOur 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 NazianzusDo you conceive of your Lord as less because? He shows that humiliation is the best road to exaltation (cf. Mt. 23:12); because He humbles Himself for the sake of the soul that is bent down to the ground, that He may even exalt within Himself that which is bent double under a weight of sin?... If so, you must blame the physician for stooping over suffering and putting up with evil smells in order to give health to the sick?
