Trinity Sunday

"Of the Father’s love begotten, ere the worlds began to be,
He is Alpha and Omega, He the source, the ending He,
Of the things that are, that have been,
And that future years shall see, evermore and evermore!

"O that birth forever blessèd, when the virgin, full of grace,
By the Holy Ghost conceiving, bare the Savior of our race;
And the Babe, the world’s Redeemer,
First revealed His sacred face, evermore and evermore!

"Christ, to Thee with God the Father, and, O Holy Ghost, to Thee,
Hymn and chant with high thanksgiving, and unwearied praises be:
Honor, glory, and dominion,
And eternal victory, evermore and evermore!"

--Of the Father's Love Begotten, 5th Century Latin hymn


"The Father is the deity subsisting in the prime, unoriginated and most absolute manner, or the deity in its direct existence. The Son is the deity [eternally] generated by God's understanding, or having an idea of Himself and subsisting in that idea. The Holy Ghost is the deity subsisting in act, or the divine essence flowing out and breathed forth in God's infinite love to and delight in Himself. And . . . the whole Divine essence does truly and distinctly subsist both in the Divine idea and Divine love, and that each of them are properly distinct persons."

--Jonathan Edwards, "Essay on the Trinity"
