The church, therefore, as it is in via, does not face the world as the exclusive possessor of salvation, nor as the fullness of what others have in part, the answer to the questions they ask, or the open revelation to what they are anonymously. The church faces the world, rather, as an arrabon of that salvation - as sign, firstfruit, token, witness of that salvation which God purposes for the whole . . . It must therefore live always in dialogue with the world, bearing its witness to Christ but always in such a way that it is open to receive the riches of God that belong properly to Christ but have to be brought to him . . . It will continue to change as it meets new cultures and lives in faithful dialogue with them.
