What do Catholics say of the observance of Sunday by Protestants?

Answer

"It was the Catholic Church which, by the authority of Jesus Christ, has transferred this rest to the Sunday
in remembrance of the resurrection of our Lord. Thus the observance of Sunday by the Protestants is an
homage they pay, in spite of themselves, to the authority of the [Catholic] church. "-"Plain Talk About the
Protestantism of Today," by Mgr. Segur, page 213.
