The plurality of churches...should not be interpreted as something willed by God, as a normal unfolding of the wealth of grace given to mankind in Jesus Christ [nor as] a necessary trait of the visible, empirical Church, in contrast to the invisible, ideal, essential Church. Such a distinction is entirely foreign to the New Testament because, in this regard also, the Church of Jesus Christ is one. She is invisible in terms of the grace of the Word of God and of the Holy Spirit,...but visible in signs in the multitude of those who profess their adherence to her; she is visible as a community and in her community ministry, visible in her service of the word and sacrament.... It is impossible to escape from the visible Church to the invisible.

If ecumenical endeavor is pursued along the lines of such a distinction, however fine the words may sound, it is philosophy of history and philosophy of society - it is not theology. People who do this are producing their own ideas in order to get rid of the question of the Church's unity, instead of facing the question posed by Christ.... If we listen to Christ, we do not exist above the differences that divide the Church: we exist in them.... In fact, we should not attempt to explain the plurality of churches at all. We should treat it as we treat our sins and those of others.... We should understand the plurality as a mark of our guilt. (K. Barth, Die Kirche und die Kirchen. Theol., 9-10).

Meeting in Korea in mid-July, the World Methodist Conference signed the joint declaration on justification that the Catholic Church and the World Lutheran Federation had signed in 1999. The conference, which represented 70 million Methodists around the world, also declared that "it is our deep hope that in the near future we shall also be able to enter into closer relationships with Lutherans and the Roman Catholic Church" and approved a resolution authorizing further dialogue with the Catholic Church, with the stated aim of "full communion in faith, mission and sacramental life." Lutheran and Catholic leaders praised the decision. "We have overcome a theological difference which has divided Western Christianity since the time of the Reformation," said Ishmael Noko, the general secretary of the World Lutheran Federation. Cardinal Walter Kaspar, president of the Pontifical Council for Promoting Christian Unity, called the statement "a gift from God" and "one of the principal successes of ecumenical dialogue." At a meeting with the conference's leaders, Pope Benedict XVI said that their signing the declaration "would contribute to the reconciliation that we ardently desire and would be a significant step toward the objective of full and visible unity in the faith."
