Endurance, since you started this thread with your interpretation of Romans 6, I thought you might like to also dissect Romans 14.
Romans 14:1-12
14:1 Now accept the one who is weak in faith, but not for the purpose of passing judgment on his opinions. 2 One man has faith that he may eat all things, but he who is weak eats vegetables only. 3 Let not him who eats regard with contempt him who does not eat, and let not him who does not eat judge him who eats, for God has accepted him. 4 Who are you to judge the servant of another? To his own master he stands or falls; and stand he will, for the Lord is able to make him stand. 5 One man regards one day above another, another regards every day alike. Let each man be fully convinced in his own mind. 6 He who observes the day, observes it for the Lord, and he who eats, does so for the Lord, for he gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God. 7 For not one of us lives for himself, and not one dies for himself; 8 for if we live, we live for the Lord, or if we die, we die for the Lord; therefore whether we live or die, we are the Lord's. 9 For to this end Christ died and lived again, that He might be Lord both of the dead and of the living. 10 But you, why do you judge your brother? Or you again, why do you regard your brother with contempt? For we shall all stand before the judgment seat of God. 11 For it is written,
"As I live, says the Lord, every knee shall bow to Me,
And every tongue shall give praise to God."
12 So then each one of us shall give account of himself to God.
NAS
By your interpretation of 1 John 3:4 and what Jesus taught concerning the Law; Paul is teaching people the dietary laws (and the Sabbath) are a matter of personal choice, which makes Paul a man who teaches Christians to transgress the Levitical Law.
On the Sabbath thread I asked you to explain this:
Colossians 2:16-19
16 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-- 17 things which are a mere shadow of what is to come; but the substance belongs to Christ. 18 Let no one keep defrauding you of your prize by delighting in self-abasement and the worship of the angels, taking his stand on visions he has seen, inflated without cause by his fleshly mind, 19 and not holding fast to the head, from whom the entire body, being supplied and held together by the joints and ligaments, grows with a growth which is from God. NAS
Here again Paul is teaching the dietary laws are moot.
What you have failed to take into consideration with your disgust (I would label your feelings hate) for Christianity as a whole is that the 1st century church had a major obstacle to contend with and that obstacle was merging two diverse communities. On the one hand you have the Hebrews with over a thousand years of adherence to the Law and their traditions. On the other hand you have the gentiles who were totally devoid of this long cultural bias. So while the Jewish apostles who understood and taught God's truth went out of their way not to offend the Hebrews they also did not water down God's revealed truth concerning the New Covenant, which set believers in Christ free from the Law and put them under His grace.
Galatians 5:1
5:1 It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery. NAS
You whole thesis is to place men back under the “yoke of slavery” to an Old Covenant (the Law).
