108 But we do not wish to turn a blind eye to the spiritual and moral values of the various non-Christian religions, for we desire to join with them in promoting and defending common ideals in the spheres of religious liberty, human brotherhood, education, culture, social welfare, and civic order. Dialogue is possible in all these great projects, which are our concern as much as theirs, and we will not fail to offer opportunities for discussion in the event of such an offer being favorably received in genuine, mutual respect.
