With the decree on Ecumenism the Catholic Church abandons its own isolation which was grounded in the feeling of self-sufficiency. This decree contains some assertions which uphold Roman «ecclesiocentrism» and an «ecumenical» method of «return». Besides this conservative position, however, the decree includes other assertions which stress the sacramentality of the Church, the presence of the sacramentality particularly in Oriental Churches, the «noteworthy» values of non-catholic people, the will to forgive and to ask forgiveness in a charitable climate. Such a document should not be regarded as a goal but, on the contrary, as a starting-point (pp. 597-615).
