Ecumenists believe that the recent convergence text The Church: Toward a Common Vision (tcv) rides on the success of Baptism, Eucharist, and Ministry (bem) and offers churches a way forward in the quest for Christian unity. This article productively imagines the future of a reconciled unity on the basis of tcv. I will use the notion of 'productive recognition' as a springboard to launch this image of 'productive ecumenism'. Churches need to reframe what they have historically understood as fundamental challenges to unity. Only then can they envision 'what if we could?' and replace 'but we can't!'. This invitation expresses ecumenism in terms of confessions, sacramentalities, and the witness of the gospel.
