What is the purpose of a question like this?
Just rying to figure out if he was reading his belief of that purpose for fellowship into the context of the scripture of Matthew 12:1-8
So there ya go, you don't see it!
Here's an attempt to change that
...Who created the Sabbath? ..the Creator did. Who is the Creator? Jesus! Colossians 1:16 (check the context) 'For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him'
Am I a sabbath keeper?....yes, I am
....in fact I approve all of God's Commandments.....even when they convince me of sin.
I say as John Newton (who coined the song 'Amazing Grace') says, 'two things I know, I am a great sinner and Christ is a great Saviour'
If you are going outside the context of Matthew 12:1-8 to other scripture as referring your belief to that purpose, then of course I am not going to see it.
If you sinned once in not keeping the sabbath, then one cannot be considered a sabbath keeper.
John 5:31 If I bear witness of myself, my witness is not true.
John 7:18 He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him. 19 Did not Moses give you the law, and yet none of you keepeth the law? .....
When someone speaks of himself in keeping the law or even his commitment to follow Christ, he does it by seeking his own glory for doing it & religious men of the world are associated with such commitments to praise the men for doing them, and yet by the law & by that commitment is the knowledge of sin. It is a false witness to testify of ourselves anyway.
We must decrease for Him to decrease. John 3:28-30
When a believer testify of His faith in Christ in how He is helping us to follow Him, we become witnesses of Him in seeking His glory.
When a believer testify of keeping the sabbath or his commitment to follow Christ, that is to his glory as a religious man.
A believer cannot do both. Alcoholic Anonymous & narcotic Anonymous are familiar with commitments and choosing their higher power of whatever they wish that high power to be, and although the recipients of anniversary coin for being sober give that credit to their higher power, his sponsors and those in his group all rolled their eyes at their higher power and instead give the credit to the addict for keeping his commitment.
No one can see that believer's faith in Jesus Christ doing it when he is being double-minded about testifying he is doing it by keeping his commitment.
I cannot see how a sabbath day keeper escape this false testimony other than to say thanks to Jesus Christ, I honor the Lord that day without referring to it as a commandment in keeping.
No believer has ever boast of being a "Loving Others Keeper" or being a "Honor thy Father & Mother Keeper" when Jesus Christ is why & how we do what we do. By testifying of ourselves, it sets one up to be judged when they do not do it and thus cannot be called a "Keeper".
If we live by faith in Jesus Christ, then by the grace of God & His help, He helps us to abide in His words in following Him as His disciples and not serve any thing else in His name nor be known by any other banner for which men can glorify themselves under.
That is why Jesus had set me free from all man made yokes of bondage as I do not look to any law to do the best I can, not even to love others, but to Jesus Christ to help me to follow Him thus declaring my faith in God to do it by His grace & by His help.
It is not our sincerity that we are to be witnesses of, but His sincerity to help us in all things so that sinners look for our hope in Jesus Christ, too.
