What is wrong with the disciplines which have emanated from Vatican II?
The 1983 Code of Canon Law contains the heresy of Vatican II concerning the Church, mentioned above. It also permits sacrilege to the Blessed Sacrament, by approving of its reception by non-Catholics, which is a mortal sin, and permits communicatio in sacris (common public worship) with non-Catholics, which is a mortal sin. In addition, the Ecumenical Directory of 1993 permits ecumenical practices which have always been taught by the Church to be mortally sinful.
