Abstract
Courage is a mandatory requirement when it comes to anticipating a future. The unity of the Church is a shared future that all ecumenical partners have to anticipate. The author first explains the virtues required and the methods to anticipate in ecumenism whilst promoting the complementarity between dialogue and testimony. He then determines the necessary conditions for a possible unification of the Churches and the means to produce the courage of anticipating a common future. He finally asserts, "Ecumenism is at the heart of the Christian tradition and of its capacity of self reinterpretation' and self 'regeneration' according to and in association with its historical situation"
