Eusebius

“Constantine saw with his own eyes the trophy of a cross of light in the heavens, above the sun, and bearing this inscription: conquer by this. At the sight, he himself was struck with amazement and his whole army also.”

“But he alone having reached our deep corruption, he alone having taken upon himself our labors, he alone having suffered the punishments due for our impieties, having recovered us who were not half dead merely, but were already in tombs and sepulchers, and altogether foul and offensive, saves us, both anciently and now, by his beneficent zeal, beyond the expectation of any one, even of ourselves, and imparts liberally of the Father's benefits—he who is the giver of life and light, our great Physician and King and Lord, the Christ of God.”

“For he alone, as the only all-gracious Son of an all-gracious Father, in accordance with the purpose of his Father's benevolence, has willingly put on the nature of us who lay prostrate in corruption, and like some excellent physician, who for the sake of saving them that are ill, examines their sufferings, handles their foul sores, and reaps pain for himself from the miseries of another, so us who were not only diseased and afflicted with terrible ulcers and wounds already mortified, but were even lying among the dead, he has saved for himself from the very jaws of death. For none other of those in heaven had such power as without harm to minister to the salvation of so many.”

“May I be an enemy to no one and the friend of what abides eternally.May I never quarrel with those nearest me, and be reconciled quickly if I should. May I never plot evil against others, and if anyone plot evil against me, may I escape unharmed and without the need to hurt anyone else.May I love, seek and attain only what is good. May I desire happiness for all and harbor envy for none.May I never find joy in the misfortune of one who has wronged me.May I never wait for the rebuke of others, but always rebuke myself until I make reparation.May I gain no victory that harms me or my opponent.May I reconcile friends who are mad at each other.May I, insofar as I can, give all necessary help to my friends and to all who are in need.May I never fail a friend in trouble.May I be able to soften the pain of the grief stricken and give them comforting words.May I respect myself.May I always maintain control of my emotions.May I habituate myself to be gentle, and never angry with others because of circumstances.May I never discuss the wicked or what they have done, but know good people and follow in their footsteps. [Prayer to practice the Golden Rule]”

“May I gain no victory that harms me or my opponent. May I reconcile friends who are mad at each other. May I, insofar as I can, give all necessary help to my friends and to all who are in need. May I never fail a friend in trouble.-- Prayer on the Golden Rule (abridged)”

“I myself have read the writings and teachings of the heretics, polluting my soul for a while with their abominable notions, though deriving this benefit: I was able to refute them for myself and loathe them even more.”
