Then, Benedict XVI explained what it means "to reinstate the unity of all Christians". "Such unity he said is epitomised, according to our belief, by the Catholic Church, with no chance of being lost. However, it does not mean consistency in all the expressions of theology and spirituality, in all forms of liturgy and discipline. Unity in plurality and plurality in unity". In this respect, Benedict XVI highlighted that a "prerequisite" for such coexistence to become a reality is that efforts towards unity "should be renewed all the time, grow and develop". In this respect, dialogue "is more than an exchange of opinions: it is an exchange of gifts in which the churches and the church communities can offer their treasures. It is just thanks to these efforts that we can walk on, step by step, as far as a full-fledged unity".
