Should Jewish Christians not work on Saturday or Sunday? I am Jewish, and this presents additional issues for me if I am considering Christianity, that non Jewish Christians don't have. For example, as far as I understand the Catholic Church has held that the covenant with the Jews has never been revoked

I mean if you read your own Bible, you can see a very strong case for believing that the Covenant Israel had with God was binding for ever and on all of their descendants - which includes Jews today:

So Jews are instructed to rest on the "Sabbath day". And it is indisputable that throughout the entire time of Jewish History, that was the 7th day. Genesis talks about God resting on the 7th day. Yet, the Ecumenical councilat Nicaea ultimately proclaimed that Christians' sabbath should be on the 1st day of the week - which we call Sunday in English.

So what's a Jew supposed to do? When they are a Christian, that is! In your answer, please tell us what your denomination is and what position it holds on the matter.

PS: If your answer includes saying that the Covenant with Israel has been superceded, then please explain how exactly we are supposed to read the verses in biblelaw101.com above
In the book of Romans Paul clearly shows that this is a matter for each individual to make up their own mind about. All Christians have freedom from the Mosaic Law, so decide for yourself what you think will help you to practice godliness and be in the best position to serve others. And keep reconsidering it, because it may be wise to change your decision later.


  One person considers one day more sacred than another; another considers every day alike. Each of them should be fully convinced in their own mind. Whoever regards one day as special does so to the Lord. Whoever eats meat does so to the Lord, for they give thanks to God; and whoever abstains does so to the Lord and gives thanks to God. For none of us lives for ourselves alone, and none of us dies for ourselves alone. If we live, we live for the Lord; and if we die, we die for the Lord. So, whether we live or die, we belong to the Lord. For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living. (Romans 14:5-9, NIV)
