A Catechism for Girls and Boys

Part II: Questions about The Ten Commandments
Disclaimer: I believe Christ fulfilled the Sabbath and there isn’t such a thing as a “Christian Sabbath.” I’m not sure how I’d change this question if I were to use this catechism.
Do you agree with this question and answer? If not, would you change it? How?
50. Q. What day of the week is the Christian Sabbath?
A. The first day of the week, called the Lord’s Day.
