Paul utilized the Sabbath during his evangelistic efforts Acts 13:14,42,44; 16:13; 18:4 - To Teach Jews about Jesus. It was his custom whenever he came to a new city Acts 17:1-3

Paul taught that the Law of Moses, including the Sabbath, had come to an end .That Jews died to the Law when they became Christians Romans 7:4-7 That Jesus ended the Law with its ordinances through His death Ep 2:13-16; Col 2:14
That the Law and ordinances like the Sabbath and circumcision should not be bound on others, especially Gentiles Col 2:16-17; Ga 5:1-4

Mainly that a new, superior covenant had replaced the old 2nd Cor 3:6-11; Hebrews 8:6-13; 9:15

They taught observing the Sabbath was no longer necessary
Jewish Christians continued to observe elements of the Law
Ac 21:18-20
Paul himself did so on occasion - Ac 18:18,21; 21:21-26
But Paul (and the rest of the apostles) drew a clear line:
The Law could not be bound on Gentiles - Ac 15:1-2,19-29; Ga 2:3-5; 5:1 The Law could not serve as a basis for their salvationGa 5:4; Ro 3:28

But if an individual desired to keep one day above another (e.g., the Sabbath), that was between the individual and his Lord - cf. Ro 14:5-6
There is nothing in the apostolic practice and writings to suggest that the Sabbath was made a part of the New Covenant of Jesus Christ

CHRISTIANS ASSEMBLED ON THE FIRST DAY!!!
Expressed both explicitly and implicitly in the NT - Acts 20:7; 1st Co 16:1-2
We meet on the 1st day of the week just like the Christians in the NT did, to remember our Lord with the Lord’s Supper.

Paul taught that the Law of Moses, including the Sabbath, had come to an end .

This argument is a long stretch from the truth and it is a cleverly concocted argument that has mislead many into comfortably believing God changed the Sabbath to Sunday.

First of all, The Ten Commandments are God's Law, not Moses'.

Secondly, the historical reason that you worship on Sunday is because that is the day instituted by Constantine in 321 A.D., which was basically summoned and ratified on the Council of Nicea in the year 325 A.D.

The only thing null and void here is your theological argument concerning God's Moral Law and the Sabbath.

I am more inclined to bear witness to the Truth and confide in the words of Jesus himself regarding the veracity of God's Law at that time and for Eternity:

Mat 5:17 KJV - Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.

Mat 5:18 KJV - For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.

Mat 5:19 KJV - Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach [them], the same shall be called great in the kingdom of heaven.

Of course, even this passage can and has been misinterpreted, but it doesn't get much clearer than this...
