Catholicism has absolutes, too many for many Catholics.
The Protestants have it easy, fewer absolutes.
Protestants also have no obligatory Sunday Mass, no holy days of obligation, no first Holy Communion, no obligatory Confirmation, no Holy Communion at least once a year, no confession ever, no penances, no Lenten fast, no Advent time, no abstinence from meat, no divorce-remarry, no nuns, no rosary and no Stations of the Cross.
I agree with your reading of the Church of England.
Islam will be as strong as their families, not unlike any faith. I lived in Saudi Arabia five years with my husband, who worked for ARAMCO. It was quite an education for us. There were as many lukewarm Muslims as their were anything else. They HAD to do the prayers five times a day but God reads hearts, not obligatory prayers with no heart behind them.
“Protestants also have no obligatory Sunday Mass, no holy days of obligation, no first Holy Communion, no obligatory Confirmation, no Holy Communion at least once a year, no confession ever, no penances, no Lenten fast, no Advent time, no abstinence from meat, no divorce-remarry, no nuns, no rosary and no Stations of the Cross.”
As coincidentally, neither does the Bible.
