By the unity of the Church we mean the unity of belief, worship, and government for all peoples and for all times in the one religious body. This is the first great requirement of the true Church. Unity is reality. Unity and life, in fact, go together. If the Church is the union of God with man, and man with God, how can there be several different Churches? That would mean division in the very thing that should unite us in God. If God is one, and men are one in Christ, then there can be but one Church, a divine yet human organization, of which Christ is the Head, the Holy Spirit the Soul, and all men members. The Church is but a continuation of Christ in this world. Therefore, St. Paul asks, "Is the body of Christ divided?" There is but one Lord, one faith, one baptism, and one Church. The Catholic Church is this one Church; and any religion which differs in character from the Catholic Church, and wishes to exist independently of it, is outside the true Church.
The Catholic Church has always had unity. It is true that there has been crisis after crisis in her history. But that does not imply loss of unity. In all life, whether individual or social, civil or religious, crisis follows crisis. But where civil kingdoms have been dissolved, the Catholic Church has ever emerged with a still more concentrated unity. Today there is no possibility of a Greek schism or a Protestant reformation by any movement from within the Catholic Church. Modernism was soon settled as far as she was concerned. And all previous disloyalties and rebellions provoked a reaction of unity proving the vitality of the Catholic Church, and that will to live which is her preservation. What you call the concentration of unity in the Catholic Church is merely her interior principle of control responding to the complications incidental to growth.
Continued tolerance of error can never give unity in truth. By such tolerance people will remain as divided as ever in their beliefs. Respect for the persons of others should ever prevail. Closer cooperation is not enough. Perfect cooperation is necessary. But that will be possible only under a unified control. And a unified control of a perfectly united Christian Church will result only from a return of the Churches which caused a division to the one fold of the Catholic-Church. After all, Christ sent His Church to fight the forces of evil. If a country sent an army to resist its enemies, how would that army get on if different subordinate officers walked off with groups of soldiers, disobeying orders of the higher command, and deciding to try out what they thought to be better ideas of their own? Discipline and order are essential. Our Lord knew this, and warned against such divisions, saying, "A kingdom divided against itself cannot stand." And if superior officers protested against the indiscipline of hotheaded subordinates, would you blame them? Or suggest that, since all aimed at defending the country, they should work harmoniously with these insubordinates, whilst still allowing them to do as they please?
The resultant religion certainly would not be Christianity. Instead of being the religion of Christ, it would be a religion which all those putting their heads together would agree that it would be nice for Him to have taught. Just imagine one saying, "Well, I am convinced that Christ taught this, but you are convinced that He taught something else. But now, let us not bother about the authority of Christ. I'll give up a section of what I am convinced to be His teaching; and you give up a section of what you are convinced to be His teaching, and thus we will arrive at a working agreement to suit ourselves." Surely you can see how impossible is such an attitude. After all, to whom does the Christian religion belong? It belongs, not to us, but to Christ. For the Catholic Church, therefore, there can be no question of compromise.
That will never be. The Catholic Church will never abandon such of her truths as Protestants dislike, in order to embrace the various errors all Protestants will generously agree amongst themselves to accept in a spirit of real good fellowship. How you can talk of a new Church is a mystery. Christ established a definite Church, promising to be with it all days till the end of the world. That does not suggest the abolition of all existent Churches and the formation of a new one. As a matter of fact, another true Christian Church would demand another Christ, and another Incarnation. But to what purpose? What would a new Christ do that the first Christ has not done? No. Christ established a definite Church to last for the rest of time, promising that the gates of hell will never prevail against it. They have not done so. And that definite Church of Christ is the Catholic Church. To her men must return.
