14 For how are our eyes made whole? That as by faith we perceive Christ “passing by” in the temporal economy, so we may attain to the knowledge of Him as “standing still” in His unchangeable Eternity. For then is the eye made whole when the knowledge of Christ's Divinity is attained. Let your love apprehend this; attend ye to the great mystery which I am to speak of. All the things which were done by our Lord Jesus Christ in time, graft faith in us. We believe in the Son of God, not on the Word only, “by which all things were made;” but on this very Word, “made flesh that He might dwell among us,” who was born of the Virgin Mary, and the rest which the Faith contains, and which are represented to us that Christ might “pass by,” and that the blind, hearing His footsteps as He “passes by,” might by their works “cry out,” by their life exemplifying the profession of their faith.
But now in order that they who cry out may be made whole, “Jesus stands still.” For he saw Jesus now “standing still” who says, “Though we have known Christ after the flesh, yet now henceforth know we Him no more.” For he saw Christ's Divinity as far as in this life is possible. There is then in Christ the Divinity and the Humanity. The Divinity “stands still,” the Humanity “passes by.” What means, The Divinity “stands still”? It changes not, is not shaken, does not depart away.
For He did not so come to us, as to depart from the Father; nor did He so ascend as to change His place. When He assumed Flesh, it changed place; but God assuming Flesh, seeing He is not in place, does not change His place. Let us then be touched by Christ “standing still,” and so our eyes be made whole. But whose eyes? The eyes of those who “cry out” when He is “passing by;” that is, who do good works through that faith, which has been dispensed in time, to instruct us in our infancy.
