Dear Sir;
Is the accusation true, that Protestants accuse you of? They say you
changed the Seventh Day Sabbath to the, so-called, Christian Sunday:
Identical with the First Day of the week. If so, when did you make the
change, and by what authority?
Yours very truly,
J. L. Day

Dear sir:
Regarding the change from the observance of the Jewish Sabbath to the
Christian Sunday, I wish to draw your attention to the facts:
> (1) That Protestants, who accept the Bible as the only rule of faith
> and religion, should by all means go back to the observance of the Sabbath.
The fact that they do not, but on the contrary observe the Sunday, stultifies
them in the eyes of every thinking man.
(2) We Catholics do not accept the Bible as the only rule of faith.
Besides the Bible we have the living Church, the authority of the Church,
as a rule to guide us. We say, this Church instituted by Christ, to teach
and guide men through life, has the right to change the Ceremonial laws of
the Old Testament and hence, we accept her change of the Sabbath to the Sunday.
We frankly say, "yes, the Church made this change, made this law, as she
made many other laws, for instance, the Friday Abstinence, the unmarried
priesthood, the laws concerning mixed marriages, the regulation of Catholic
marriages, and a thousand other laws."
