That's certainly a post biblical traditional view. Nobody in biblical times thought it wise to overthrow the Lord's sabbaths and institute man made ones. <
Earlier you referred to the Lord's sabbath as the "Jewish " sabbath. While true that some Jews observe the Lord's sabbath, it's not true that it's the Jew's sabbath.
Lev 23:3 'Six days shall work be done, but the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work on it; it is the Sabbath of the LORD in all your dwellings.
Exo 20:8 "Remember the Sabbath day, to keep it holy.
Exo 20:9 Six days you shall labor and do all your work,
Exo 20:10 but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates.
So the Lord, Jesus Christ, declared his sabbath long ago. The Lord, Jesus Christ, kept his sabbath. Christians, those who follow Christ, should likewise honor the Lord by honoring His sabbath.
Oh??
Romans 14
1Accept him whose faith is weak, without passing judgment on disputable matters. 2One man's faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables. 3The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. 4Who are you to judge someone else's servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.
5One man considers one day more sacred than another; another man considers every day alike. Each one should be fully convinced in his own mind. 6He who regards one day as special, does so to the Lord. He who eats meat, eats to the Lord, for he gives thanks to God; and he who abstains, does so to the Lord and gives thanks to God. 7For none of us lives to himself alone and none of us dies to himself alone. 8If we live, we live to the Lord; and if we die, we die to the Lord. So, whether we live or die, we belong to the Lord.
