Although I don't believe people should stay home when there is an altar where the Blessed Sacrament IS.
However, if there is no such altar within a resonable distance, then a person would receive more grace to stay home and pray their 15 decade rosary.
Jesus Christ founded one Church, and it was not the Anglican or Protestant Church, it was the Catholic church, and the NO is not it. They may have our buildings, relics, art but they do not have the same Faith.
Jesus Christ is the same yesterday, today and forever, and that is how I know the NO is not Catholic. Catholic is a Divine Institution, not your neighborhood social Country Club, where things can change with a whim.
It is true that only God can judge or look into a persons soul, to see their grace, but He also gave us His teachings.
