7 All this, Venerable Brethren, We believe and expect with unshakable faith. But this does not prevent us also, according to the measure given to each, from exerting ourselves to hasten the work of God - and not merely by praying assiduously: "Arise, O Lord, let not man be strengthened" ( Ib . ix., 19), but, more important still, by affirming both by word and deed and in the light of day, God's supreme dominion over man and all things, so that His right to command and His authority may be fully realized and respected. This is imposed upon us not only as a natural duty, but by our common interest. For, Venerable Brethren, who can avoid being appalled and afflicted when he beholds, in the midst of a progress in civilization which is justly extolled, the greater part of mankind fighting among themselves so savagely as to make it seem as though strife were universal? The desire for peace is certainly harbored in every breast, and there is no one who does not ardently invoke it. But to want peace without God is an absurdity, seeing that where God is absent thence too justice flies, and when justice is taken away it is vain to cherish the hope of peace. "Peace is the work of justice" ( Is . xxii., 17). There are many, We are well aware, who, in their yearning for peace, that is for the tranquillity of order, band themselves into societies and parties, which they style parties of order. Hope and labor lost. For there is but one party of order capable of restoring peace in the midst of all this turmoil, and that is the party of God. It is this party, therefore, that we must advance, and to it attract as many as possible, if we are really urged by the love of peace.
