Deus Dei Filius, dilectissimi, lux et veritas, Jesus Christus, emissus a Patre, inter rebelles et adversus alterutrum concupiscentes, carnem ac spiritum, medius intercessit; solvensque veteres inimicitias, tandem in semetipso pacem reformavit. Neque hoc quanta facilitate Omnipotens potuit, sed quanta charitate et patientia benignissimum decuit, et quanta eruditione hebetudo nostra indiguit. Quod enim saepe jam diximus, Deus non solum ut redimeret, sed ut erudiret, hominem suscepit. Totum ergo hominem, id est carnem de carne Adam, ob quem se Filium hominis crebro nuncupat, et spiritum rationalem suscipiendo, simul semelque sanctificavit; diu vero, ac per omnes fere aetates, quomodo gerendus esset, gerendo edocuit. Itaque dum ipso Dei Filio, id est Patris Verbo agente et deducente, Filius hominis, id est caro, sive homo noster exterior, defectui concupiscentiarum suarum appropinquat; desideratae luci ipso adducente spiritum approximat. Nonne ipse in seipso Filium hominis, id est carnem de homine sumptam, jejuniis et eremi squalore, fame et siti, labore et fatigatione, vigiliis et disciplinis, fatigavit, attenuavit, exsiccavit fortiter: quam postea vinculis et flagris, sputis et colaphis, spinis et clavis, et impiorum manibus exposuit crudeliter, sicut scriptum est: Terra tradita est in manus impiorum? (Job IX.) Ut ergo Jerusalem Filius hominis ascendat, deducente Dei Filio, Jericho appropinquat, ipsoque adduci jubente caecus ad lumen repedat (Luc. XVIII); quia ut caro ad pacem sui spiritus proficiat, necesse est ut per Dei gratiam a sua carnalitate deficiat, et ut spiritus rationalis ad intelligentiae lumen redeat, necesse est deficiente carnalitate, eadem adducente gratia, ad Dei Verbum haud segnis accedat, sicut scriptum est: Accedite ad eum, et illuminamini (Psal. XXXIII). Utrumque nobis, dilectissimi, sicut impossibile est, sic Dei Filio factu facile. Quid enim nos nisi tenebrae et vanitas: ipse autem lux et veritas? Nisi ergo in nobis sit et operetur Dei Filius, nec a malo deficimus, nec ad bonum proficimus, nec a vanitate cadimus, nec ad veritatem surgimus. Verumtamen sicut in illo Dei Filius natura carnem et animam suscepit, gratia alteram a concupiscentia excaecans, et alteram ad sapientiam illuminans, cum sit a Patre naturaliter unus, sumpta tamen nostra dualitate effectus, quodammodo substantiis trinus, naturis geminus, persona permanens unus: ita, frater,
God the Son of God, beloved, the light and the truth, Jesus Christ, sent forth by the Father, stepped in as mediator between the rebels that lust against one another, the flesh and the spirit; and, dissolving the old enmities, at last restored peace in Himself. And this not with such ease as the Almighty could have done it, but with such charity and patience as befitted the Most Kind, and with such teaching as our dullness needed. For, as we have often said already, God took up man not only to redeem him but to instruct him. Taking up, then, the whole man, that is, flesh from the flesh of Adam, on whose account He often calls Himself the Son of man, and a rational spirit, He sanctified him all at once and once for all; but over a long time, and through almost all the ages, by bearing him He taught how he was to be borne. And so, while, by the working and leading of the Son of God Himself, that is, the Word of the Father, the son of man, that is, the flesh, or our outer man, draws near to the waning of its concupiscences, the spirit, by His leading, approaches the longed-for light. Did He not in Himself weary, wear down and dry up vigorously the Son of man, that is, the flesh taken from man, with fasts and the squalor of the desert, hunger and thirst, labour and fatigue, vigils and disciplines; and afterwards expose it cruelly to bonds and scourges, spittings and blows, thorns and nails, and the hands of the ungodly, as it is written: The earth is given into the hands of the ungodly? (Job 9.) That the Son of man, then, may go up to Jerusalem, the Son of God leading Him, He draws near to Jericho, and at His command to be brought the blind man returns to the light (Luke 18); because, for the flesh to advance to peace with its spirit, it must by the grace of God wane from its carnality, and for the rational spirit to return to the light of understanding, it must, as carnality wanes, by the leading of the same grace, approach the Word of God without sloth, as it is written: Come to Him, and be enlightened (Ps. 33). Both of these, beloved, as they are impossible for us, so are easy for the Son of God to do. For what are we but darkness and vanity, and He the light and the truth? Unless, then, the Son of God is in us and works in us, we neither wane from evil nor advance to good, neither fall away from vanity nor rise to truth. Yet just as in Him the Son of God by nature took up flesh and soul, by grace blinding the one to concupiscence and enlightening the other to wisdom, and, though by nature one with the Father, having taken our twofoldness He became in a manner threefold in substances, twin in natures, remaining one in person: so, brother,
