I have given references, perspectives, biblical points of view but you just don't like what the bible teaches.
And yet you failed to show direct commands from the Lord and His Apostles in the New Covenant requiring Christians to have church on Saturday
And you failed to show warnings given by the Lord and His Apostles in the New Covenant that tell us not having church on Saturday is a sin and what happens to people who do not have church on Saturday
Galatians 4:9-11 - But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage?Ye observe days, and months, and times, and years.I am afraid of you, lest I have bestowed upon you labour in vain.
Romans 14:5 - 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.”
Counsel of Jerusalem in Acts 15
The Saturday peoples can never overcome the Counsel of Jerusalem in Acts 15 where the Lord did NOT lead them to include observing Saturday sabbath... unless the Saturday peoples want to claim the Apostles were being led by devils in the Book of Acts and not being led by the Lord.
If they say the Apostles were being led by the Lord at the the Counsel of Jerusalem, then they must accept the Apostles teachings as being from the Lord.... and accept observing Saturday sabbath is not applicable under the New Covenant.
But, if they don't accept the Apostles teachings as being from the Lord at the Counsel of Jerusalem then the Saturday peoples must concede that they believe the Apostles were listening to devils which is why they did not teach the people about observing Saturday sabbath.
Acts 15:28,29 - For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things;That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
The Saturday peoples apparently do believe the Apostles in the Book of Acts were being led by devils.
