"_That they may be all one!_" This ideal of the Master, this supreme wish of His last hours, remains the ideal, the wish of His Church. But its realization cannot be at the expense of truth. Cardinal Gasparri outlined to the promoters of the "World Congress on Faith and Order" the view and position of the Catholic Church in this most important issue. "The Holy See has decided not to participate in the Pan-Christian Congress which it is proposed to hold shortly, _as the Catholic Church considering her dogmatic character, cannot join on an equal footing with the other Churches_. The feeling at the Vatican is that all other Christian denominations have seceded from the Church of Rome, which descends directly from Christ. Rome cannot go to them; _it is for them to return to her bosom_.[4] The Pope is ready to receive the representatives of the dissenting churches with open arms, since the Roman Church has always longed for the _unification of all Religious Christians_. Pope Leo XIII. was deeply interested in this question and wrote two famous encyclicals on the subject of the _unification of the Christian Churches_." The divine Founder of Christendom did not leave to several Churches the conservation and propagation of His doctrine. He founded only one Church and gave "unity" itself, as the supreme test of its divinity. Therefore the Church, that has remained "one" through time and space, and has conquered those two great enemies of unity, bears the birth-mark of its divine origin. The Catholic Church alone makes that specific claim. History is there to substantiate it. Matthew Arnold himself could not help acknowledging this universal fact. "Catholicism is that form of Christianity which is the oldest, the largest, and most popular. It has been the great popular religion of Christendom. Who has seen the poor in other churches as they are seen in Catholic Churches? Catholicism envelopes human life, and Catholics in general feel themselves to have drawn not only their religion from their Church, but they feel themselves to have drawn from her, too, their art, poetry and culture. _And if there is a thing specially alien to religion, it is division. If there is a thing specially native to religion it is peace and union. Hence the original attraction towards unity in Rome, and hence the great charm when that unity is once attained_." The sharp contrast between the actual restlessness and uncertainty of the dissident Churches, and the calm assurance and self-possession of the Catholic Church, is not that an abiding proof of the security of the Catholic position?
