The Roman Catholic vision of ecumenism is founded on the will of Christ and the shared communion of all Christians through baptism. The “soul of the whole ecumenical movement,” is a “change of heart” and “holiness of life” along with “public and private prayer for the unity of Christians.” These three together are called “spiritual ecumenism” by the Second Vatican Council’s Decree on Ecumenism (#8).
“There is one body and one spirit – one Lord, one faith, one baptism, one God and Father of us all”. Eph.4;4-5
