Isaac Williams quotes:

In ways and thoughts of weakness and of wrong, Threads turn to cords, and cords to cables strong.

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.
