Fr. Bill addresses the obligation to celebrate Sunday Mass and answers the questions:
Why do Catholics go to Mass on Sundays?
How did the command “Keep Holy the Sabbath” shift from an observance on Saturday for the Jewish People to Sunday for Christians?
Why Pope, Bishops and Priests?
What is the role of the Pope in relation to the Bishops (and previous Popes)?
In what sense is the Pope Infallible?
What if the Pope does not speak infallibly (ex cathedra)?
