The Church, therefore, exhorts her sons, that through dialogue and collaboration with the followers of other religions, carried out with prudence and love and in witness to the Christian faith and life, they recognize, preserve and promote the good things, spiritual and moral, as well as the socio-cultural values found among these men.
via Declaration on the Relation of the Church to non-christian religions – Nostra Aetate.
In the context of the Second Vatican Council, His Holiness Pope Paul VI made the proclaimation “Nostra Aetate” on October 28, 1965. It ends with those words:
No foundation therefore remains for any theory or practice that leads to discrimination between man and man or people and people, so far as their human dignity and the rights flowing from it are concerned.
The Church reproves, as foreign to the mind of Christ, any discrimination against men or harassment of them because of their race, color, condition of life, or religion. On the contrary, following in the footsteps of the holy Apostles Peter and Paul, this sacred synod ardently implores the Christian faithful to “maintain good fellowship among the nations” (1 Peter 2:12), and, if possible, to live for their part in peace with all men, so that they may truly be sons of the Father who is in heaven.
