Bishop Conlon talks about Vatican II Council's Decree on the Ecumenism, called "The Restoration of Unity" -- in Latin it is called "Unitatis Redintegratio." He outlines the basic Catholic principles of ecumenism, which is that they are based on Biblical teachings so that any Christian would understand and accept what the Church is teaching. Also, the principles are established by Jesus and infused with the Holy Spirit and made one by the Holy Spirit.
