What are we forbidden from doing on the Sabbath Marie ?

There are many legalists who would say we can do this or not do that on the Sabbath etc.etc , just as it was in the Apostles time.

I just finished :"The Mystery of Israel" by H L Ellison and he makes a good point when he says :" Whenever Christian moralists have sought to work out a fixed code for Christian behavior, both the methods used and the results have had a markedly general resemblance to those of the Jewish "legalists" they rejected out of hand."
