12. When, therefore, you hear it said, “Sin shall not reign over you;”45 Rom. vi. 14 have not thou confidence of thyself, that sin reign not over thee, but of Him, unto Whom a certain Saint saith in prayer, “Direct my paths after Thy Word, and let no iniquity have dominion over me.”46 Ps. cxix. 133 For lest haply, after that we had heard, “sin shall not reign over you,” we should lift up ourselves, and lay this to our own strength, straightway the Apostle saw this, and added, “For ye are not under the Law, but under Grace.” Therefore, Grace causeth that sin reign not over you. Do not thou, therefore, have confidence of thyself, lest it thence reign much more over thee. And, when we hear it said, “If by the Spirit ye shall mortify the deeds of the flesh, ye shall live,”47 Rom. viii. 13 let us not lay this so great good unto our own spirit, as though of itself it can do this. For, in order that we should not entertain that carnal sense, the spirit being dead rather than that which putteth others to death, straightway he added, “For as many as are led by the Spirit of God, these are sons of God.”48 Rom. viii. 14 Therefore that by our spirit we may mortify the works of the flesh, we are led by the Spirit of God, Who gives Continence, whereby to curb, tame, overcome lust.
CAPUT V.
12. Non fidat de se qui vult peccati concupiscentiam 0357 vincere. Excusatio peccatorum cohibenda per continentiam. Excusationes in peccatis diversae. Fati accusatio, fortunae, diaboli, Dei vero ipsius a Manichaeis. Cum ergo audis, Peccatum vobis non dominabitur; noli de te fidere, ut peccatum tibi non dominetur; sed de illo cui dicit orans quidam sanctus, Itinera mea dirige secundum verbum tuum, et non dominetur mihi omnis iniquitas (Psal. CXVIII, 133). Etenim ne forte, cum audissemus, Peccatum vobis non dominabitur, nos ipsos extolleremus, et viribus nostris hoc tribueremus, statim hoc vidit Apostolus, atque subjecit, Non enim estis sub lege, sed sub gratia (Rom. VI, 14). Gratia itaque facit ut peccatum tibi non dominetur. Noli ergo de te fidere, ne multo amplius inde tibi dominetur. Et cum audimus, Si spiritu actiones carnis mortificaveritis, vivetis; non hoc tantum bonum spiritui nostro, quasi per se ipsum possit ista, tribuamus. Nam ne istum carnalem sensum spiritu mortuo potius quam mortificante saperemus, illico addidit, Quotquot enim Spiritu Dei aguntur, hi filii sunt Dei (Id. VIII, 13, 14). Itaque ut spiritu nostro opera carnis mortificemus, Spiritu Dei agimur qui dat continentiam, qua frenemus, domemus, vincamus concupiscentiam.
