Leo XIII Quotes
To the shepherds alone was given all power to teach, to judge, to direct; on the faithful was imposed the duty of following their teaching, of submitting with docility to their judgment, and of allowing themselves to be governed, corrected, and guided by them in the way of salvation. Thus, it is an absolute necessity for the simple faithful to submit in mind and heart to their own pastors, and for the latter to submit with them to the Head and Supreme Pastor.
Leo XIII, Pope. Epistola Tua. Vatican Polyglot Press, 17 June 1885.
Pope Leo XIII was the head of the Catholic Church from 20 February 1878 to his death in 1903. He was the oldest pope (reigning until the age of 93), with the exception of Pope Benedict XVI as emeritus pope, and had the third-longest confirmed pontificate, behind those of Pius IX (his immediate predecessor) and John Paul II.
