Jesus tells us that there is ONLY ONE DOOR to enter heaven and He is the DOOR. Because private interpretation of the Word of God leads to the multiplication of religions with different creeds, undoubtedly some of us will miss the heavenly door. Because God reveals ONLY ONE DOOR to enter heaven, it is urgent to teach people the dangers of private interpretation leading to misundestandings of Divine Revelation. Jesus confided to Peter and his successors down through centuries the assistance of the Holy Spirit toguide as pilgrims of eternity.

Jesus confided Peter and his successors, under the guidance of the Holy Spirit, to guide us down through centuries to our heavenly Eternal rest in the Glory of the Blessed Trintiy.
