Last time I checked Constantine was not God nor Christ.Sports Fan,
Jesus said he did not come to destroy the law heaven and earth is still here that is NT
Also, Jews and Non Jews went to same assemblies in Acts there are your Gentiles Sports Fan that observed the Sabbath. Then we have in Acts people together one Sunday with Paul to pray and worship. However, there is no word about SABBATH being changed. They just gathered together because Paul was leaving the following day.
According to history Constantine in 321 AD changed Sabbath to Sunday so the Christians can worship with the pagans in honor of Sun(Baal).
The Sabbath was not certified to be on any specific day for the GENTILE.
That is like saying that because Pres Obama took away the day of prayer for our nation, that now we are required to no longer pray.
Again STAY on subject and quit making yourself look less credible with every post.
The NEW Testiment church was given FREEDOM over several of the traditions of the Jew, and one of those traditions was practicing the sabbath in a manner where it became something being done out of commitment, rather than one being done out of reverence and love.
Romans 14.. end of discussion.
A quote: VERSE 5 "One 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. "
Maybe your problem is you look to much to mans books than learning Gods book in context.
