11 And since, as We have said, We place Our hope above all in the providence and mercy of God. We repeatedly, urge you, Venerable Brothers, not to cease encouraging and promoting this zealous crusade of prayer. Through it - with the intercession of His Mother, the Virgin Mary - may Almighty God in His goodness grant an end to the threat of war, a happy solution to the conflicting claims of nations, and assurance everywhere, to the common benefit of all, of those rights granted the Church by her Divine Founder. Thus may "the whole human family, which has been rent asunder by sin's wound, be brought under the sway of His most sweet rule." ( Prayer for the Feast of Christ the King )
