Feeneyism is a Christian doctrine, associated with Leonard Feeney, which advocates an interpretation of the dogma extra Ecclesiam nulla salus ("outside the Church there is no salvation") which is that only Catholics can go to heaven and that only those baptised with water can go to heaven. Feeneyism opposes the doctrines of baptism of desire and baptism of blood as well as the view that non-Catholics can go to heaven. Feeneyism is considered a heresy by the Catholic Church; some Catholics refer to Feeneyism as the Boston heresy.
