"I'll make it even shorter for him.
I don't acknowledge the words of men, but simply the canon of scripture. He's making my point by citing proof aside from scripture...traditions of men. No word of Christ, God, the only BEING able to make a day holy.
Col. 2:16 - isn't it interesting you haven't put aside drinking or eating. Best for you to check the context of the text when it is clearly speaking of holy days, new moons, sabbaths (of which there were many aside from the SABBATH day.
Gal. 4 - again speaking of days, months, seasons, years. Not specifically speaking of the holy Sabbath. The people were zealous of law...no longer being under the CURSE of the law...that means that the law, while it curses the sinner, the curse of the law is lifted through Christ, being the perfect fulfillment of the law! The law is not a curse to the perfect human. The law points at sin (Rom. 7:7) See the context of chapter 4 with Gal. 5:4-6. What's the only thing that counts? Faith expressing itself through what? Oh...it says LOVE. See Romans 13:10. It seems one of us is not reading context, but interpreting traditions of men into the texts.
Romans 6:14-18 - read the whole point. The law is holy, righteous and good (Rom. 7:12) so if you are slaves to righteousness, then you are sons and daughters to obedience (vs 16) which leads to righteousness. (Rom. 7:22...I delight in God's law.)
See Romans 8:1-4 and onwards - There is no condemnation (that being the condmenation that the law says you and me are sinners since we have broken the law) The law of the Spirit of life set me free from the law of sin and death (the law points at sin and condemns a sinner as a sinner and thus to death) The law is powerless to "to do", that is the law has no power to save a sinner. The law simply states what sin is and thus condemns those who sin. The law is weakened by the sinful nature. Christ came in the likeness of sinful man, but without the sinful nature so the law has no power of Him or anyone IN HIM. Christ condemed sin and became a sin offering. "in order that the righteous requirements of the law be fully met." would be met in us through Him. If they were righteous enough for Christ to write with His own hand, and die for so that we could be declared righteous through Christ, how do you remove that which is righteous without ONE WORD from the ONE that makes things or days holy and laws holy, righteous and good?
Acts 20:7 - a religious meeting does not a holy day make. That which proves too much, proves nothing.
1 Cor. 16:2 - So because Paul says to set money aside doing your personal finances on Sunday so that when he comes, which is not a specific day mind you, you're not scrambling to figure out what to give...that is your proof for a change in the holy day? LOL!!
Heb. 4:8-10 - Really? It's clear. "...the same also hath rested from his works" points at the 7th day of Creation and it also point at Christ's death whereby the only full day Christ "rested" in death was the Sabbath! Next.
Heb. 7:11-13 - I agree, Christ is the new Priest...but no where does it state a "new law"...and there is no word from God of such, but traditions of men. See Mark 7:8
Rev. 1:9-10 - LOL...I really feel for you here. What was the vision about? The Lord's day is the day of His return! The vision is clear that that is the context. Really?
See Isa. 13:6,9, Eze. 13:5, 30:3, Joel 1:15, 2:1,11,31, 3:14, Amos 5:18,20, Ob. 1:15, Zep.1:7,14, Zec. 14:1, Mal. 4:5, Acts 2:20, 1Cor. 5:5, 2Cor. 1:14, 1Thess. 5:2, 2Thess. 2:2, 2Peter 3:10.
John surely recognizes the Lord's day. Problem for you is that his vision fits in context of all the above. No where else is the term "the Lord's day" used nor does it refer to the Sabbath or Sunday at all.
Let's be honest.
I'll keep it short and stop here for his sake."
