Barlaam and Ioasaph

Again therefore Barlaam took up his parable and said, "If thou wilt learn who is my Master, it is Jesus Christ the Lord, the only-begotten Son of God, ‘the blessed and only potentate, the King of kings, and Lords of lords; who only hath immortality, dwelling in the light which no man can approach unto'; who with the Father and the Holy Ghost is glorified. I am not one of those who proclaim from the housetop their wild rout of gods, and worship lifeless and dumb idols, but one God do I acknowledge and confess, in three persons glorified, the Father, the Son, and the Holy Ghost, but in one nature and substance, in one glory and kingdom undivided. He then is in three persons one God, without beginning, and without end, eternal and everlasting, uncreate, immutable and incorporeal, invisible, infinite, incomprehensible, alone good and righteous, who created all things out of nothing, whether visible or invisible. First, he made the heavenly and invisible powers, countless multitudes, immaterial and bodiless, ministering spirits of the majesty of God. Afterward he created this visible world, heaven and earth and sea, which also he made glorious with light and richly adorned it; the heavens with the sun, moon and stars, and the earth with all manner of herbs and divers living beasts, and the sea in turn with all kinds of fishes. ‘He spake the word and these all were made; he commanded and they were created. ' Then with his own hands he created man, taking dust of the ground for the fashioning of his body, but by his own in-breathing giving him a reasonable and intelligent soul, which, as it is written, was made after the image and likeness of God: after his image, because of reason and free will; after his likeness, because of the likeness of virtue, in its degree, to God. Him he endowed with free will and immortality and appointed sovran over everything upon earth; and from man he made woman, to be an helpmeet of like nature for him.

"And he planted a garden eastward in Eden, full of delight and all heart's ease, and set thereto the man whom he had formed, and commanded him freely to eat of all the heavenly trees therein, but forbade him wholly the taste of a certain one which was called the tree of the knowledge of good and evil, thus saying, ‘In the day that ye eat thereof ye shall surely die. ' But one of the aforesaid angel powers, the marshall of one host, though he bore in himself no trace of natural evil from his Maker's hand but had been created for good, yet by his own free and deliberate choice turned aside from good to evil, and was stirred up by madness to the desire to take up arms against his Lord God. Wherefore he was cast out of his rank and dignity, and in the stead of his former blissful glory and angelic name received the name of the ‘Devil' and ‘Satan' for his title. God banished him as unworthy of the glory above. And together with him there was drawn away and hurled forth a great multitude of the company of angels under him, who were evil of choice, and chose in place of good, to follow in the rebellion of their leader. These were called Devils, as being deluders and deceivers.
