“The ecumenical dialogue and the interreligious dialogue are connected and overlap, but are not identical with each other another. There is a specific, qualitative difference between them and, therefore, they should not be confused. Ecumenical dialogues are not only based on the tolerance and respect due for every human and religious conviction; nor are they founded solely on liberal philanthropy or mere polite courtesy; on the contrary, ecumenical dialogue is rooted in the common faith in Jesus Christ and the reciprocal recognition of baptism, which means that all the baptized become members of the one Body of Christ (cf. Gal 3,28); I Cor 12,13; Ut unum sint, n. 42) and can pray the"Our Father” together, as Jesus taught us. In other religions the Church recognizes a ray of that truth “that enlightens every man” (Jn 1,9), but is revealed in its fullness only in Jesus Christ; only he is “the Way, the Truth and the Life” (Jn 14,6; cf. Nostra aetate, n. 2). It is therefore ambiguous to refer to interreligious dialogue in terms of macro-ecumenism or of a new and vaster phase of ecumenism.
Christians and the followers of other religions can pray, but cannot pray together. Every form of syncretism is to be excluded."
