CHAPTER XLIII—THAT JESUS CHRIST, AT THE SAME TIME GOD AND MAN, IS THE TRUE AND MOST EFFICACIOUS MEDIATOR.
But the true Mediator, Whom in Thy secret mercy Thou hast showed to the humble, and sentest, that by His example also they might learn that same humility, that Mediator between God and man, the Man Christ Jesus, appeared betwixt mortal sinners and the immortal just One; mortal with men, just with God: that because the wages of righteousness is life and peace, He might by a righteousness conjoined with God make void that death of sinners, now made righteous, which He willed to have in common with them. Hence He was showed forth to holy men of old; that so they, through faith in His Passion to come, as we through faith of it passed, might be saved. For as Man, He was a Mediator; but as the Word, not in the middle between God and man, because equal to God, and God with God, and together one God.
How hast Thou loved us, good Father, who sparedst not Thine only Son, but deliveredst Him up for us ungodly! How hast Thou loved us, for whom He that thought it no robbery to be equal with Thee, was made subject even to the death of the cross, He alone, free among the dead, having power to lay down His life, and power to take it again: for us to Thee both Victor and Victim, and therefore Victor, because the Victim; for us to Thee Priest and Sacrifice, and therefore Priest because the Sacrifice; making us to Thee, of servants, sons by being born of Thee, and serving us. Well then is my hope strong in Him, that Thou wilt heal all my infirmities, by Him Who sitteth at Thy right hand and maketh intercession for us; else should I despair. For many and great are my infirmities, many they are, and great; but Thy medicine is mightier. We might imagine that Thy Word was far from any union with man, and despair of ourselves, unless He had been made flesh and dwelt among us.
Affrighted with my sins and the burden of my misery, I had cast in my heart, and had purposed to flee to the wilderness: but Thou forbadest me, and strengthenedst me, saying, Therefore Christ died for all, that they which live may now no longer live unto themselves, but unto Him that died for them. See, Lord, I cast my care upon Thee, that I may live, and consider wondrous things out of Thy law. Thou knowest my unskilfulness, and my infirmities; teach me, and heal me. He, Thine only Son, in Whom are hid all the treasures of wisdom and knowledge, hath redeemed me with His blood. Let not the proud speak evil of me; because I meditate on my ransom, and eat and drink, and communicate it; and poor, desired to be satisfied from Him, amongst those that eat and are satisfied, and they shall praise the Lord who seek Him.
