From St. Ambrose’s Exposition of the Christian Faith – Book 1, Chapter XIII
81. Peter, when he saw Moses and Elias on the mountain, with the Son of God, was not deceived as to their nature and glory. For he enquired, not of them, but of Christ what he ought to do, inasmuch as though he prepared to do homage to all three, yet he waited for the command of one. But since he ignorantly thought that for three persons three tabernacles should be set up, he was corrected by the sovereign voice of God the Father, saying, "This is My dearly beloved Son: hear ye Him." That is to say: "Why dost thou join thy fellow-servants in equality with thy Lord? "This is My Son." Not "Moses is My Son," nor "Elias is My Son," but "This is My Son." The Apostle was not dull to understand the rebuke; he fell on his face brought low by the Father's voice and the glorious beauty of the Son, but he was raised up by the Son, Whose wont it is to raise up them that are fallen. Then he saw one only, the Son of God alone, for the servants had withdrawn, that He might be seen to be Lord alone, Who alone was entitled Son.
82. What, then, was the purpose of that vision, which signified not that Christ and His servants were equal, but betokened a mystery, save that it should be made plain to us that the Law and the Prophets, in agreement with the Gospel, revealed as eternal the Son of God, Whom they had heralded. When we, therefore, hear of the Son coming forth of the womb, the Word from the heart, let us believe that the Son was not fashioned with hands but begotten of the Father, not the work of a craftsman but the offspring of a parent.
83. He, therefore, Who said, "This is My Son," said not, "This is a creature of time," nor "This being is of My creation, My making, My servant," but "This is My Son, Whom ye see glorified." This is the God of Abraham, the God of Isaac, the God of Jacob, Who appeared to Moses in the bush, concerning Whom
Moses saith, "He Who is hath sent me." It was not the Father Who spake to Moses in the bush or in the desert, but the Son. It was of this Son that Stephen said, "This is He Who was in the church, in the wilderness, with the Angel." This, then, is He Who gave the Law, Who spake with Moses, saying, "I am the God of Abraham, the God of Isaac, the God of Jacob." This, then, is the God of the patriarchs, this is the God of the prophets.
84. It is of the Son, therefore, that we read, thy mind understandeth the reading, let thy tongue make confession. Away with arguments, where faith is required; now let dialectic hold her peace, even in the midst of her schools. I ask not what it is that philosophers say, but I would know what they do. They sit desolate in their schools. See the victory of faith over argument. They who dispute subtly are forsaken daily by their fellows; they who with simplicity believe are daily increased. Not philosophers but fishermen, not masters of dialectic but taxi-gatherers, now find credence. The one sort, through pleasures and luxuries, have bound the world's burden upon themselves; the other, by fasting and mortification, have cast it off, and so doth sorrow now begin to win over more followers than pleasure.

Holy Martyr and Archdeacon Laurence, August 10
Aflame with the Spirit like a living coal thou didst burn up the thorns of error, O blessed trophy-bearer Laurence, archdeacon of Christ. Like rational incense thou didst become a whole burnt offering to Him Who magnified thee. Wherefore shelter from all assaults of the enemy those who glorify thee.
Kontakion, Tone Two
With divine fire thou didst kindle thy heart, O Laurence and reduce the fire of the passions to ashes. O staff of athletes, Godbearing Martyr, thou didst cry with faith while contesting: No one will separate me from the love of Christ.
