It is a push to unify Christianity across denominational lines. The concept, of course "sounds" good but in practice this could only come at the cost of considerable compromise of both bad and good, wrong and right. It does not necessarily mean that "the fights come to a halt" but rather that "the right to believe differently" is, to obtain this ecumenism is sacrificed in the name of "unification." Sort of like a Dictatorship's path to over throwing a democracy.
