a)Your comment on Mark2:27 about Jesus saying "not just for Jews" is made up to be deceptive about what Jesus really said.)
Does it? Jesus said:
Mark 2:27 The sabbath was
made for man
Maybe you can find the missing words of 'Jew' in this sentence. Jesus said this after the Pharisee's was accusing Jesus of breaking God's Sabbath, which He wasn't and therefore was keeping God's Sabbath. Jesus is our perfect example and He taught all about the Sabbath and kept the Sabbath Luke 4:16 and we are told to
follow in Christ's footsteps. Luke 9:23-25
b)The fact that Jesus is Lord of the Sabbath means He is not subject to it, because He officiates as the High Priest does. That's why Jesus referenced Abiathar the high priest allowing David to eat the showbread.
God's Sabbath started from Creation and will continue for eternity. Jesus kept God's Sabbath and all of God's laws and told us to as well. John 14:15, John 15:10, 1 John 5:3
Genesis 2:2 And on
the seventh day God ended His work which He had done, and
He rested on the seventh day from all His work which He had done. 3
Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.
God does not to rest. God rested from all His work as an example to man. Notice man was created on the sixth day and the very next day is God's Sabbath. Do you really think the first man and women did not keep God's Sabbath holy, the only day in the
entire Bible that God blessed and sanctified? Which is why throughout the bible the Sabbath is referenced as God's holy day and
only holy day. God's Sabbath day will be a day of worship for eternity. Isaiah 66:23 for all those who are saved.
Mark 2:27 speaks in the singular to teach that a man's need (for food) trumps the ceremonial observation, as in the example Jesus gave (Mark 27:23-28,
Mat 12:1–8; Luk 6:1–5 )
You should probably re-read these scriptures again carefully in prayer. Jesus is not teaching about the need for food here. He is teaching about the Sabbath. He is teaching that the Pharisees were making God's Sabbath something it was not. He was teaching we should do good on God's Sabbath and eating is not a sin on Sabbath. The Pharisees was concerned more about what people were doing on God's Sabbath than the delight God intended Sabbath to be. A special day of communion with our Savior. Isaiah 58:13,14
c) You should research 'if' the term "the Lord's day" is a reference to the Sabbath day or not.
Usually when one makes a statement like this they back it up with scripture, which I see you did not. Maybe you can show me one scripture in the entire bible that says the first day is God's holy day, or a day God blessed or sanctified or the Lord's day or God's Sabbath day.
Instead God wrote this with His own hand:
Exodus 20: 10
But the seventh day is the
sabbath of the Lord thy God:
Similar to what Jesus said:
Mark 2:28 Therefore the Son of Man is also Lord of the Sabbath.”
This is God's authority! He is our Creator and Savior!
The seventh day Sabbath is God's only chosen sacred day period. When we obey God's commandments we are obeying God's authority and not the authority of man that Jesus warned us about:
Mathew 15:9 But in vain they do worship me, teaching
for doctrines the commandments of men.
Keeping Sunday holy or the "lords day" is coming from the Roman Catholic church and not from a commandment of God.
It is well to remind the Presbyterians, Baptists, Methodists, and all other Christians, that the Bible does not support them anywhere in their observance of
Sunday.
Sunday is an institution of the Roman Catholic Church, and those who observe the day observe a commandment of the Catholic Church.
—Priest Brady, in an address, reported in the Elizabeth, NJ ‘News’ on March 18, 1903.
Protestants ... accept
Sunday rather than Saturday as the day for public worship after the Catholic Church made the change... But the Protestant mind does not seem to realize that ... in observing
Sunday, they are accepting the authority of the spokesman for the Church, the pope.
—Our Sunday Visitor, February 5th, 1950.
There is no commandment from God or Jesus that does away with God's 4th commandment that God asked us to REMEMBER, which is the opposite what is being taught today and as predicted in scripture. Daniel 7:25
I want to enrage the devil by keeping God's commandments. This pleases the Lord thy God. 1 John 5:2 Revelations 12:17, Revelations 14:12 and Jesus is my Master and Redeemer, not anyone else.
