I read your words. When you quote Scripture, you do well. When you write the musings of man and go counter to Gods Word, you do not do well.
You quote "The Son of man is Lord, even of the Sabbath" and go on to say Sunday is the Lords Day. That is talking out of both sides of the mouth. I can show you where there is a commandment by God to keep the Sabbath Day holy but you cannot show me a commandment to keep Sunday holy. Jesus and the Apostles were observant Jews. And regardless of what your colleague says, they observed the Sabbath. They kept it holy. They taught others to do the same.
It is not in Scripture of the change of solemnity of Sabbath to Sunday. Can you tell me what/when is the exact origin of this change? And by whose authority?

True, but not the Gentiles.

Acts 15:

And they wrote letters by them after this manner; The apostles and elders and brethren send greeting unto the brethren which are of the Gentiles in Antioch and Syria and Cilicia:
Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:
It seemed good unto us, being assembled with one accord, to send chosen men unto you with our beloved Barnabas and Paul,
Men that have hazarded their lives for the name of our Lord Jesus Christ.
We have sent therefore Judas and Silas, who shall also tell you the same things by mouth.
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.
So when they were dismissed, they came to Antioch: and when they had gathered the multitude together, they delivered the epistle:
Which when they had read, they rejoiced for the consolation.

No, in the scripture the 15th Day of His 1st month is the Sabbath.
The help reinforce that biblical Truth, the day before that day, 14th Day, Christ the Passover Lamb finished His Work and was slain in accordance with the scriptures.

And the day after the Sabbath of the 15th, aka the 16th Day, Feast of First Fruits/wavesheaf, Christ rose as First Fruits.

The scriptures prove out His 14th,15th,16th Days being His 6th Day, 7th Day Sabbath and 1st Day..

Rome has changed that first importance of the gospel into their own fake days and fake Roman Jesus because they did what the scriptures predicted..

Rome’s Friday, Saturday,Sunday is as fake as their December 25, January 1 and February 2 teachings..

None of that is in the bible. Yet it’s treated as world wide truth that eventually will fall..

And that clumps all religions in the same Babylonian boat in the end times..

Friday keepers, Saturday keepers and Sunday keepers.
All Babylonian
