Ecumenism and pro-existence

This article by Jerry Ryan examines the question of Christian unity through the lens of contemporary ecumenism. Adopting both a theological and ecclesiological approach, the author proposes moving beyond the mere coexistence of Churches to achieve what he calls "pro-existence," that is, an existence oriented toward the other rather than simply parallel. The central idea is that the undivided Church of the first millennium constitutes the reference model for any Christian reunification. The article analyzes the major doctrinal obstacles — papal primacy, infallibility, Marian dogmas — by proposing contextualized rereadings likely to make them less divisive. On the theological level, the author emphasizes that confessional divisions have paradoxically allowed each tradition to develop complementary charisms, the synthesis of which would enrich a renewed universal Church.
