Bolehkah Gereja-Gereja Kristen Tetap Terpisah?

The author starts from the clear statement of the Second Vatican Council, “that the Church is a single flock, there are not many Churches. God established a single Church by sending His Son and the Spirit”. Today, the “separated” Churches”, are in real communion, although the communion is not yet complete. Through baptism all Christians, in each of the Christian Chruches, are members of the one Body of Christ. This is a strong bond and has to be taken as more resilient than any differences that may diminish unity. Therefore we must ask: what must be regarded as a difference that is significant enough to grant one the right to deem one's Church as still separated? This article outlines the eight theses of Heinrich Fries and Karl Rahner where they show, with detalied argumentation, that today the Christian Churches can come together in communion. The article draws to the conclusion that the Christian Church has a moral obligation to live in a communion that is already possible, and has no right to state that the Churches can remain separated from each other.
