I. One of the singular glories of Our Lord’s Humanity is that He is “holy, innocent, undefiled, separated from sinners, and made higher than the heavens” (Heb. vii. 26). This supreme quality of holiness and sinlessness proceeds in the first instance from the union of the Divine Person of the Word with the Humanity. That fact necessarily perfects the human nature of the same Person beyond all conception. The body and soul of Jesus Christ are the body and soul of God the Son. That Divine Person guides and rules them and acts through them with infinite perfection and holiness. The Sacred Humanity of Our Lord is therefore holy and spotless beyond the holiness of all angels and men, and beyond the holiness of the Immaculate Virgin, although she was absolutely stainless in every respect. Our Blessed Lord, as man, is then the supreme work of God’s creative power, beyond which nothing can be more perfect and holy. Not only is this most glorious to God, but it is a great glory to the human race that God should have conferred on it such a distinction, not granted even to the angels. We have all a share in this dignity: for the human race, taken in its entirety as including Jesus Christ, presents a sum of holiness surpassing even that of the whole host of heaven. You individually, when free from sin, and especially in Holy Communion, have a share in that holiness. Take care never to lose this privilege by mortal sin.
II. A second thing which makes a soul incapable of sin is the sight of God, which confers beatitude. This was the case with the Sacred Humanity. From the first moment of its human existence the soul of Christ enjoyed the Beatific Vision; it had attained from the first to its final aim and object, the fruition of the Divine Essence. Two things are involved in this, the clear vision of God and perfect love of Him. The soul, knowing and possessing the supreme good, cannot be deluded into choosing anything inferior, and still less anything contradictory, in its stead. Perfected love, further, cannot hate God, or, which is the same thing, cannot love that which is repugnant to Him. If you sin, it is because you do not know God thoroughly, because you do not see Him with the sight of vivid faith, or because you do not love Him above all things. The practical result of religion is to keep you sinless, and make you by degrees more holy, by promoting in you, first, a fuller knowledge, and then a fuller love of the supreme good. Strengthen these in your soul till “neither death nor life . . . nor things present, nor things to come . . . shall be able to separate us from the love of God, which is in Christ Jesus Our Lord” (Rom. viii. 38, 39).
III. Another thing that restrains from sin is a clear knowledge of the nature of sin, its enormity, and foulness; and this is dependent on our knowledge of God. We know these things, during this life, more by the testimony of God than by direct evidence, so that their reality does not come home to us. Our Lord alone had perfect knowledge. He could see the surpassing horror of sin and the misery it involves, more than the blessed do in heaven or the lost in hell. He saw it as the deadly enemy and the antithesis of His Divinity. He hated it beyond all things, and was infinitely removed from it. He could see that which is so close to us and so dear to us, but which would kill us with horror if we could only glance beneath the veil of pretended goodness and deceptive pleasure which hides its real character. He knows that all the pains of hell apart from sin would be a less misery than the presence of one mortal sin in the soul. Hence He hates it with a necessary and eternal hatred. Strive to realize these truths, and acquire the spirit of Christ, so as to be ready to do all things and suffer all things rather than consent to a single mortal sin.
