The late Father Ian Ker edited Selected Sermons by Newman for the Paulist Press "Classics of Western Spirituality" series. In the section of his Introduction titled "The Influence of the Greek Fathers", Father Ker highlights the impact they had on Newman's thought as demonstrated by excerpts from the Parochial and Plain Sermons.
It was the thought of the Greek Fathers that shaped and guided Newman's reading of Scripture, out of which emerged that great corpus of sermons, the Parochial and Plain Sermons, one of the enduring classics of Christian spirituality. (p. 28)
Thus the Son of God became the Son of Man; mortal, but not a sinner; heir of our infirmities, not of our guiltiness; the offspring of the old race, yet {32} "the beginning of the" new "creation of God." . . . Thus He came, selecting and setting apart for Himself the elements of body and soul; then, uniting them, to Himself from their first origin of existence, pervading them, hallowing them by His own Divinity, spiritualizing them, and filling them with light and purity, the while they continued to be human, and for a time mortal and exposed to infirmity. . . .Great is our Lord, and great is His power, Jesus the Son of God and Son of man. Ten thousand times more dazzling bright than the highest Archangel, is our Lord and Christ. By birth the Only-begotten and Express image of God; and in taking our flesh, not sullied thereby, but raising human nature with Him, as He rose from the lowly manger to the right hand of power,—raising human nature, for Man has redeemed us, Man is set above all creatures, as one with the Creator, Man shall judge man at the last day. So honoured is this earth, that no stranger {40} shall judge us, but He who is our fellow, who will sustain our interests, and has full sympathy in all our imperfections.
The Word became flesh to make us "partakers of the divine nature":78 "For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God."79 "For the Son of God became man so that we might become God."80 "The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods."8178 2 Pt 1:4.
