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 Son is 'Life' (Jn. 14:6) because He is 'Light', constituting and giving reality to every thinking being. 'For in Him we live, move and exist' (Acts 17:28) and there is a two-fold sense in which He breathes into us (cf. Gen. 2:7; Jn. 20:22); we are filled, all of us, with His breath, and those who are capable of it, all those who open their mind's mouth wide enough, with His Holy Spirit.
Gregory of NazianzusWho should listen to discussions of theology? Those for whom it is a serious undertaking, not just another subject like any other for entertaining small-talk, after the races, the theater, songs, food, and sex: for there are people who count chatter on theology and clever deployment of arguments as one of their amusements.
Gregory of NazianzusLet us not esteem worldly prosperity or adversity as things real or of any moment, but let us live elsewhere, and raise all our attention to Heaven; esteeming sin as the only true evil, and nothing truly good, but virtue which unites us to God.
Gregory of NazianzusIf time came before me, time is not before the Word, whose Begetter is atemporal. When the beginningless Father was there, leaving nothing superior to His divinity, then also was there the Father's Son, having in the Father a timeless beginning, like the sun's great circle of overwhelming clear light.
