Today we read the classic text of the ecumenical movement, which seeks full unity among all Christians. The Catholic Church officially joined this movement in 1964. Fr. Rolheiser writes that one of the most ancient problems in philosophy is the question of ‘the one and the many,’ whether reality is ultimately a unity or a plurality, and how these interrelate. We might ask the same question regarding the plurality of religious faiths, churches, and forms of worship in our world. Is there some inherent oneness there, or is it all plurality without anything binding us together in some kind of community that transcends our differences? All of us who have a sincere belief share a common faith because we ultimately share a common God. Moreover, since we share a common God, we also share a common problem; namely, we struggle equally in trying to conceptualize this non-conceptualizable God. The first dogma about God in all valid religions is that God is holy and ineffable, meaning that God can never be circumscribed and grasped in a concept. Avery Dulles taught that the way forward for Christian ecumenism and interreligious dialogue is not the way of conversion – trying to get others to convert to our particular church. The way forward (in his words) is the way of “progressive gradualism,” namely, of each of us being ever more faithful to God within our tradition so that as each of us grows closer to God (and, for Christians, to Christ), we will grow closer to each other and all people of sincere faith. The unity we seek lies not in one church or faith community, eventually converting all others to join it, but in every one of sincere faith becoming progressively more faithful to God so that the unity we desire can take place sometime in the future, contingent on our own deeper fidelity inside our own faith tradition. None of us is living out the full truth of our faith traditions. Therefore, The path forward lies in a deeper personal conversion within our own faith traditions that will lead to a more empathic relationship with other faith traditions.
