The 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 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 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 NazianzusGive something, however small, to the one in need. For it is not small to one who has nothing. Neither is it small to God, if we have given what we could.
Gregory of NazianzusI seem indeed to hear that voice, from Him Who gathers together those who are broken, and welcomes the oppressed: I have given you up, and I will help you. In a little wrath I struck you, but with everlasting mercy I will glorify you (cf. Isa. 54:8). The measure of His kindness exceeds the measure of His discipline.
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.
