Christian Unity

In the words of Pope Leo XIII:

Agreement and union of minds is the necessary foundation of this perfect concord amongst men, from which concurrence of wills and similarity of action are the natural results. Wherefore, in His divine wisdom, He ordained in His Church Unity of Faith; a virtue which is the first of those bonds which unite man to God, and whence we receive the name of the faithful – “one Lord, one faith, one baptism” (Eph. iv., 5).

That is, as there is one Lord and one baptism, so should all Christians, without exception, have but one faith. And so the Apostle St. Paul not merely begs, but entreats and implores Christians to be all of the same mind, and to avoid difference of opinions: “I beseech you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no schisms amongst you, and that you be perfect in the same mind and in the same judgment” (I Cor. 1:10).
