As far as we can reach, He Who Is, and God, are the special names of His Essence; and of these especially He Who Is, not only because when He spoke to Moses in the mount, and Moses asked what His Name was, this was what He called Himself, bidding him say to the people 'I Am has sent me' (Ex. 3:14), but also because we find that this Name is the more strictly appropriate.
Gregory of NazianzusIf anyone does not believe that Holy Mary is the Mother of God, such a one is a stranger to the Godhead.
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 not delay in coming to grace, but hasten, lest the robber outstrip you, lest the adulterer pass you by, lest the insatiate be satisfied before you, lest the murderer seize the blessing first, or the publican or the fornicator, or any of these violent ones who take the Kingdom of heaven by force (cf. Mt. 11:12). For it suffers violence willingly, and is tyrannized over through goodness.
Gregory of NazianzusChrist is born: glorify Him. Christ comes from heaven: go out to meet Him. Christ descends to earth: let us be raised on high.
Gregory of NazianzusAlmost every sin is committed for the sake of sensual pleasure; and sensual pleasure is overcome by hardship and distress arising either voluntarily from repentance, or else involuntarily as a result of some salutary and providential reversal. 'For if we would judge ourselves, we should not be judged; but when we are judged, we are chastened by the Lord, so that we should not be condemned with the world.' (1 Cor. 11:31-32).
