Today we no longer understand ecumenism in the sense of a return, by which the others would be converted and return to being catholics. This was expressly abandoned by Vatican II. - Cardinal Walter Kasper, Head of Pontifical Council for Christian UnityI would love to see the good Cardinal (or you, but I doubt you agree with him) prove that statement. I dont recall any such thing in V2, though I have quite clearly seen it in the so-called spirit of V2.

The high point of the ecumenical movement thus far has been the Joint Declaration on Justification signed by the Catholic Church and one of the largest Lutheran bodies.
The ultimate goal of the ecumenical movement is the re-unification of Christendom or the re-unification of the Catholic Church, the Church which Christ founded, the "pillar and foundation of truth," and the church which we should go to to settle disputes, as Christ instructed us.
