15 Now, how great is the necessity of this expiation or reparation, more especially in this our age, will be manifest to every one who, as we said at the outset, will examine the world, "seated in wickedness" (1 John v, 19), with his eyes and with his mind. For from all sides the cry of the peoples who are mourning comes up to us, and their princes or rulers have indeed stood up and met together in one against the Lord and against His Church (Cf. Psalm ii, 2). Throughout those regions indeed, we see that all rights both human and Divine are confounded. Churches are thrown down and overturned, religious men and sacred virgins are torn from their homes and are afflicted with abuse, with barbarities, with hunger and imprisonment; bands of boys and girls are snatched from the bosom of their mother the Church, and are induced to renounce Christ, to blaspheme and to attempt the worst crimes of lust; the whole Christian people, sadly disheartened and disrupted, are continually in danger of falling away from the faith, or of suffering the most cruel death. These things in truth are so sad that you might say that such events foreshadow and portend the "beginning of sorrows," that is to say of those that shall be brought by the man of sin, "who is lifted up above all that is called God or is worshipped" (2 Thessalonians ii, 4).
