Who gave you the ability to contemplate the beauty of the skies, the course of the sun, the round moon, the millions of stars, the harmony and rhythm that issue from the world as from a lyre, the return of the seasons, the alternation of the months, the demarcation of day and night, the fruits of the earth, the vastness of the air, the ceaseless motion of the waves, the sound of the wind?
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 NazianzusIf anyone does not believe that Holy Mary is the Mother of God, such a one is a stranger to the Godhead.
Gregory of NazianzusMay you be children of God, pure and unblameable, in the midst of a crooked and perverse generation (cf. Phil. 1:15): and may you never be entangled in the snares of the wicked that go round about, or bound with the chains of your sins. May the Word in you never be smothered with the cares of this life and so make you unfruitful: but may you walk in the King's Highway, turning aside neither to the right hand nor to the left, but led by the Spirit through the narrow gate.
Gregory of Nazianzus
