The work is the result of having been able to live, study, work and teach in an Evangelical-Protestant-Pentecostal urban academic environment for over thirty years, while also being a faithful Catholic and an Oblate of Saint John’s Abbey. In light of both the 500th year commemoration of the Protestant Reformation in 1517, and the subsequent Catholic Reformation begun in the 16th century and which continued through the Second Vatican Council and continues today, this manuscript is a contribution to an understanding of the present ecumenical situation. The work will also coincide with the 100th year anniversary of the reported apparition, prophetic message, and miracle at Fatima.
