We are not entitled to such licence, I mean that of affirming what we please; we make the Holy Scriptures the rule and the measure of every tenet; we necessarily fix our eyes upon that, and approve that alone which may be made to harmonize with the intention of those writings
Gregory of NyssaIf we truly think of Christ as our source of holiness, we shall refrain from anything wicked or impure in thought or act and thus show ourselves to be worthy bearers of his name. For the quality of holiness is shown not by what we say but by what we do in life.
Gregory of NyssaJust as at sea those who are carried away from the direction of the harbor bring themselves back on course by a clear sign, on seeing a tall beacon light or some mountain peak coming into view, so Scripture may guide those adrift on the sea of the life back into the harbor of the divine will.
Gregory of Nyssa
