Holy Quotes - page 59
Let us quake before the great Spirit, Who is my God, Who has made me know God, Who is God there above, and Who forms God here: almighty, imparting manifold gifts, Him Whom the holy choir hymns, Who brings life to those in heaven and on earth, and is enthroned on high, coming from the Father, the divine force, self-commandeered; He is not a Child (for there is one worthy Child of the One who is best), nor is He outside the unseen Godhead, but of identical honor.
Gregory of Nazianzus
As the Holy Trinity, our God is One Being, although Three Persons, so, likewise, we ourselves must be one. As our God is indivisible, we also must be indivisible, as though we were one man, one mind, one will, one heart, one goodness, without the smallest admixture of malice - in a word, one pure love, as God is Love. That they may be one, even as We are One (John 17:22).
John of Kronstadt
