The empire of Christ the King includes not only Catholic nations, not only baptized persons who, though of right belonging to the Church, have been led astray by error, or have been cut off from her by schism, but also all those who are outside the Christian faith: so that truly the whole of mankind is subject to the power of Jesus Christ.
Pope Leo XIIIWhoso turns his attention to the bitter strifes of these days and seeks a reason for the troubles that vex public and private life must come to the conclusion that a fruitful cause of the evils which now afflict, as well as of those which threaten us, lies in this: that false conclusions concerning divine and human things, which originated in the schools of philosophy, have crept into all the orders of the state, and have been accepted by the common consent of the masses.
Pope Leo XIIIOur Lord came to the aid of each great tribulation with a special devotion. The present and future tribulations of the Church and of nations are greater than at any other period, and this persecution is more dangerous than those of previous times. Hence, the devotion which God sends to the succor of His Church and of the nations at the present time is the devotion to the Most Holy Eucharist. It is the highest of all devotions.
Pope Leo XIII
