Phil36 has already answered it:
Good afternoon Marcelo,
In regards to the scriptures you use to support modern church tradition of rejecting some of God's Word.
Romans 14:5
"One man regards one day above another, another regards every day alike. Let each man be fully convinced in his own mind."
How can people use Paul's letters regarding the "Weak in Faith" as support to create their own laws, or annul a Commandments of God.
What does one man believing one thing, and another man believing another have to do with God or God's Word? Shall I reject God's Commandments because some random man doesn't believe His Words?
What are we all the be convinced of in our mind? That one man, weak in the Faith, creates our Salvation or Doctrine? Or are we to be convinced, as Paul was, that God is true and every man a liar.
Not sure how Paul's teaching regarding the weak in faith can give us the power to reject God's Word.
Galatians 4:9-11 "But now that you have come to know God, or rather to be known by God, how is it that you turn back again to the weak and worthless elemental things, to which you desire to be enslaved all over again? You observe days and months and seasons and years. I fear for you, that perhaps I have labored over you in vain."
I have asked many times for Biblical evidence that the Jews or the Pharisees were preaching God's Commandments. Everything we have been told about them exposes the Biblical fact that they were not obeying God's Laws, but the created their own.
Jer. 14:
14 Then the LORD said unto me, The prophets prophesy lies in my name:
I sent them not, neither have I commanded them, neither spake unto them: they prophesy unto you a false vision and divination, and a thing of nought,
and the deceit of their heart.
Matt. 15:
7 Ye hypocrites, well did Esaias prophesy of you, saying,
8 This people draweth nigh unto me with their mouth,
and honoureth me with their lips; but their heart is far from me.
9
But in vain they do worship me,
teaching for doctrines the commandments of men.
Acts 7:
51 Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost:
as your fathers did, so do ye.
52 Which of the prophets have not your fathers persecuted? and they have slain them which shewed before of the coming of the Just One; of whom ye have been now the betrayers and murderers:
53 Who have received the law by the disposition of angels,
and have not kept it.
54 When they heard these things, they were cut to the heart, and they gnashed on him with
their teeth.
Acts 15:
10 Now therefore why tempt ye God, to put a yoke upon the neck of the disciples,
which neither our fathers nor we were able to bear?
The preaching that the Jews were obeying God, then when they turned to Jesus, they stopped obeying God, and then they were "Bewitched" into "Returning again" the weak and beggarly elements of obedience to God, in foolishness.
This Galatians scripture, if taken in context, does in no way give anyone the power or permission to reject God's Word.
Colossians 2:16-17 "Therefore let no one act as your judge in regard to food or drink or in respect to a festival or a new moon or a Sabbath day--things which are a mere shadow of what is to come; but the substance belongs to Christ."
Col. 2:
8 Beware lest any man spoil you through philosophy and vain deceit,
after the tradition of men,
after the rudiments of the world, and not after Christ.
13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
To preach that God's Commandments, specifically His Sabbath, are against us is in direct contradiction to what Jesus instructed about His Sabbath.
Once again I am forced into choosing between what you and by extension, Mainstream Christianity preaches, and what Jesus teaches.
"The Sabbath was made by God (Jesus before becoming a man) for man".
So the Sabbath is not against us, it is not a "rudiment of the world", and it is not a "Tradition of man" regardless of what the mainstream preachers of today preach.
Therefore: 16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
17 Which are a shadow of things to come; but the body is of Christ.
This is why God commanded "Remember the Sabbath day to keep it Holy", because it is symbolic of something to come.
20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances,
21 (Touch not; taste not; handle not;
Like eating with unwashed hands or creating Laws that say you can't take a walk on God's Sabbath and eat a raspberry, as did the mainstream preachers of His time.
22 Which all are to perish with the using) after the commandments and doctrines of men?
So these scriptures actually support the Word of God, "Bring every thought into the obedience of Christ", they do not support mainstream Christian preaching that Jesus nailed God's Sabbath to the cross.
For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.
I do not perfectly understand the verse above, but I know it doesn't mean we Christians are supposed to keep the Law. Why? Because there is not one single soul on the entire planet who keeps the 613 laws.
There are not now, nor has there ever been 613 laws required by God for the common man. You can not find this preaching in the Bible anywhere.
So Marcelo, these scriptures do not in any way, support the mainstream church tradition of rejecting God's Sabbaths. I hope you can see this, or show me where I am wrong regarding the scriptures I posted.
