What do papal authorities say of the observance of Sunday by Protestants?

Answer

"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 Monsignor Segur,
page 213.
NOTE-The statement here made is true, and a full realization of the fact will lead those who
honestly, but ignorantly, have heretofore been observing Sunday as the Sabbath, to refuse longer to pay
homage to apostasy, and return to the observance of that which is the sign of loyalty to Heaven-the only
weekly day of rest which God, in His Word, has commanded men to keep holy, the seventh day.
