Let us banish from our hearts, therefore, the unbelieving opinions which imagine that evils befall us by mere chance, or from physical causes.
But when thou considerest the wounds in thy own circle of relations, or dost cast a glance at the public disorders in the State, which again afflict the individual also (as Solon says: “The general corruption penetrates even to thy quiet habitation”), then think, first, of thy own and others’ sins, and of the righteous wrath of God; and, secondly, weigh the rage of the devil, who lets loose his hate chiefly in the Church.
In all men, even the better class, great darkness reigns. We see not how great an evil sin is, and regard not ourselves as so shamefully defiled. We flatter ourselves, in particular, because we profess a better doctrine concerning God. Nevertheless, we resign ourselves to a careless slumber, or pamper each one his own desires; our impurity, the disorders of the Church, the necessity of brethren, fills us not with pain; devotion is without fire and fervor; zeal for doctrine and discipline languishes, and not a few are my sins, and thine, and those of many others, by reason of which such punishments are heaped upon us.
Let us, therefore, apply our hearts to repentance, and direct our eyes to the Son of God, in respect to whom we have the assurance that, after the wonderful counsel of God, He is placed over the family of man, to be the protector and preserver of his Church.
We perceive not fully either of our wretchedness or our dangers, or the fury of enemies, until after events of extraordinary sorrowfulness. Still we ought to reflect thus: there must exist great need and a fearful might and rage of enemies, since so powerful a protector has been given to us, even God’s Son. When He says: “No man shall pluck my sheep out of my hand,” He indicates that He is no idle spectator of woe, but that mighty and incessant strife is going on. The devil incites his tools to disturb the Church or the political commonwealth, that boundless confusion may enter, followed by heathenish desolation. But the Son of God, who holds in His hands, as it were, the congregation of those who call upon His name, hurls back the devils by His infinite power, conquers and chases them thence, and will one day shut them up in the prison of hell, and punish them to all eternity with fearful pains. This comfort we must hold fast in regard to the entire Church, as well as each in regard to himself.
