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.
The Lutheran - Catholic accord on justification was a complete disaster. In the end it accomplished nothing. How can a Lutheran be justified without professing the Catholic faith?
