Which of the following is not a principle of roman catholicism? a. the church requires members to attend mass daily. b. followers demonstrate commitment by performing seven sacraments. c. believers worship one god represented by the holy trinity. d. the pope establishes doctrine as the supreme leader of the church.

The correct answer for this question is "a. the church requires members to attend mass daily." The choice that is not a principle of Roman Catholicism is that the church requires members to attend mass daily. The Church, at least the minimum, required the baptized to attend one Mass (Easter Sunday Mass). A good Roman Catholic attends mass every Sunday.
