"Give back to me the exultation of Thy salvation" 1 (ver. 12). "Give back" what I had; what by sinning I had lost: to wit, of Thy Christ. For who without Him can be made whole? Because even before that He was Son of Mary, "In the beginning He was the Word, and the Word was with God, and the Word was God;" 2 and so, by the holy fathers a future dispensation of flesh taken upon Him, was looked for; 3 as is believed by us to have been done. Times are changed, not faith. "And with Principal Spirit confirm me." Some have here understood the Trinity in God, Itself God; the dispensation of Flesh being excepted therefrom: since it is written, "God is a Spirit." 4 For that which is not body, and yet is, seemeth to exist in such sort as that it is spirit. Therefore some understand here the Trinity spoken of: "In upright Spirit," the Son; in "Holy Spirit," Holy Ghost; in "Principal Spirit," Father. 5 It is not any heretical opinion, therefore, whether this be so, or whether "upright Spirit" He would have to be taken of man himself (when He saith, "An upright spirit renew in my inner parts"), which I have bowed and distorted by sinning, so that in that case the Holy Spirit be Himself the Principal Spirit: which also he would not have to be taken away from him, and thereby would have himself to be confirmed therein.
