St Thomas Aquinas' Lenten Meditation - Passion Monday: The Passion of *Christ* is a Remedy Against Sin
We find in the Passion of *Christ* a remedy against all the evils that we incur through sin. Now these evils are five in number.
(i) We ourselves become unclean. When a man commits any sin he soils his soul, for just as virtue is the beauty of the soul, so sin is a stain upon it. How happeneih it, O Israel, that thou art in thy enemies land? Thou art grown old in a strange country, thou art defiled with the dead (Baruch iii. 10, 11).
The Passion of *Christ* takes away this stain. For *Christ*, by His Passion, made of His blood a bath wherein He might wash sinners. The soul is washed with the blood of *Christ* in Baptism, for it is from the blood of *Christ* that the sacrament draws its power of giving new life. When therefore one who is baptised soils himself again by sin, he insults *Christ* and sins more deeply than before.
(ii) We offend God. As the man who is fleshly-minded loves what is beautiful to the flesh, so God loves spiritual beauty, the beauty of the soul. When the soul's beauty is defiled by sin God is offended, and holds the offender in hatred. But the Passion of *Christ* takes away this hatred, for it does what man himself could not possibly do, namely it makes full satisfaction to God for the sin. The love and obedience of *Christ* was greater than the sin and rebellion of Adam.
(iii) We ourselves are weakened. Man believes that, once he has committed the sin, he will be able to keep from sin for the future. Experience shows that what really happens is quite otherwise. The effect of the first sin is to weaken the sinner and make him still more inclined to sin. Sin dominates man more and more, and man left to himself, whatever his powers, places himself in such a state that he cannot rise from it. Like a man who has thrown himself into a well, there he must lie, unless he is drawn up by some divine power. After the sin of Adam, then, our human nature was weaker, it had lost its perfection and men were more prone to sinning.
But *Christ*, although He did not utterly make an end of this weakness, nevertheless greatly lessened it. Man is so strengthened by the Passion of *Christ* and the effect of Adam's sin is so weakened that he is no longer dominated by it. Helped by the grace of God, given him in the sacraments, which derive their power from the Passion of *Christ*, man is now able to make an effort and so rise up from his sins. Before the Passion of *Christ* there were few who lived without mortal sin, but since the Passion many have lived and do live without it.
(iv) Liability to the punishment earned by sin. This the justice of God demanded, namely, that for each sin the sinner should be punished, the penalty to be measured according to the sin. Whence, since mortal sin is infinitely wicked, seeing that it is a sin against what is infinitely good, that is to say, God whose commands the sin despises, the punishment due to mortal sin is infinite too.
But by His Passion *Christ* took away from us this penalty, for He endured it Himself. Who His own self bore our sins, that is the punishment due to us for our sins, in his body upon the tree (i Pet. ii. 24).
So great was the power and value of the Passion of *Christ* that it was sufficient to expiate all the sins of all the world, reckoned by millions though they be. This is the reason why baptism frees the baptised from all their sins, and why the priest can forgive sin. This is why the man who more and more fashions his life in conformity with the Passion of *Christ*, and makes himself like to *Christ* in His Passion, attains an ever fuller pardon and ever greater graces.
(v) Banishment from the kingdom. Subjects who offend the king are sent into exile. So, too, man was expelled from Paradise. Adam, having sinned, was straightway thrown out and the gates barred against him.
But, by His Passion, *Christ* opened those gates, and called back the exiles from banishment. As the side of *Christ* opened to the soldier's lance, the gates of heaven opened to man, and as *Christ*'s blood flowed, the stain was washed out, God was appeased, our weakness taken away, amends made for our sins, and the exiles were recalled. Thus it was that Our Lord said immediately to the repentant thief, This day thou shalt be with me in Paradise (Luke xxiii. 43). Such a thing was never before said to any man, not to Adam nor to Abraham, nor even to David. But This day, the day on which the gate is opened, the thief does but ask and he finds. Having confidence in the entering into the holies by the blood of *Christ* (Heb. x. 19).
