It is absolutely necessary that the Christian community be subject in all things to the Sovereign Pontiff if it wishes to be a part of the divinely-established society founded by our Redeemer.
Pope Pius XIIBy divine mandate the interpreter and guardian of the Scriptures, and the depository of Sacred Tradition living within her, the Church alone is the entrance to salvation: She alone, by herself, and under the protection and guidance of the Holy Spirit, is the source of truth.
Pope Pius XIIA day will come when the civilized world will deny its God, when the Church will doubt as Peter doubted. She will be tempted to believe that man has become God. In our churches, Christians will search in vain for the red lamp where God awaits them. Like Mary Magdalene, weeping before the empty tomb, they will ask, โWhere have they taken Him?โ
