The Catholic Church was given to us by Our Lord Jesus Christ at the price of his blood and for one reason alone – our eternal salvation.
“For, since Jesus Christ delivered Himself up for the salvation of the human race, and to this end directed all His teaching and commands, so He ordered the Church to strive, by the truth of its doctrine, to sanctify and to save mankind. But faith alone cannot compass so great, excellent, and important an end. There must needs be also the fitting and devout worship of God, which is to be found chiefly in the divine [Eucharistic] Sacrifice and in the dispensation of the Sacraments, as well as salutary laws and discipline. All these must be found in the Church, since it continues the mission of the Savior forever. The Church alone offers to the human race that religion – that state of absolute perfection – which He wished, as it were, to be incorporated in it. And it alone supplies those means of salvation which accord with the ordinary counsels of Providence.” ~Pope Leo XIII, “Satis Cognitum”, 1896
