|"And where are we told in the
Scriptures that we are to keep the
first day at all? We are commanded to keep the
seventh; but we are nowhere commanded to keep the
first day... The reason why we keep the
first day of the week holy instead of the seventh is for the same reason that we observe many other things, not because the
Bible, but because the Church, has enjoined it." Isaac Williams, Plain Sermons on the Catechism, pages 334, 336.
