The following chart gives a kind of basic taxonomy of various positions on the Sabbath within Christianity. This very helpful piece was designed by my elder, Brad Snyder. Well done, sir!
[Note, this was designed for our catechism class, which focuses on the education of our young people. Some parts could require more elucidation and explanation for adults.]

Bravo, my brethren!
I might add that the great Reformer, Luther, confused this command with the ceremonial commandments. He wrote:
“This commandment, therefore, according to its gross sense, does not concern us Christians; for it is altogether an external matter, like other ordinances of the Old Testament, which were attached to particular customs, persons, times, and places, and now have been made free through Christ.”
Therefore, a great deal of confusion has issued since then, for Luther was surely a great theologian, but also a mere man…
