Take a closer look at that commandment that the Holy Spirit says "is the first commandment with a promise' Eph 6:2
12 “Honor your father and your mother, so that your days may be prolonged on the land which the Lord your God gives you.
over half of that commandment is a promise, a blessing. No other commandment of the TEN has that.
God has other commandments besides the TEN, and there are other promises in the Bible that come before Ex 20:12. But uniquely within the TEN - we have the situation that EX 20:12 is the first commandment with a promise.
This is interesting in Eph 6 written to a gentile church - because Paul could have said "Children obey your parents... I have this command from God" or something of that sort. Instead of that Paul uses language that appeals to authority of the TEN - he specifically directs them to the unit of TEN.
That separation and distinction of the TEN that we find in Eph 6 is not without precident as Heb 9 reminds us - the TEN were kept inside the ark of the covenant and no other commands were placed inside that ark, only they are written in stone, only they are written by the hand of God directly, only they are spoken by God directly to Israel not just spoken to Moses. So God has a pattern of distinguishing that unit of TEN in both OT and NT.
No wonder they are subjected to predictable and regular opposition
You could have arrived at your conclusion regarding the Ten Commandment with out using Paul.
Do you call Paul the Holy spirit; it was Paul who said, "is the first commandment with a promise'
Eph 6:2 What did Paul mean by first; does he mean that the commandment was given out of sequence, as with the Sabbath commandment; does he mean that the Sabbath command has no promise? Duet 4:1 assigns the same promise to all the commandments. That promise is also the greeting of Spock from Star Trek.
I do not see anything wrong with Paul's use of the command , as a lesson for children; But the command is intended for adults, and it instructs the individual to do or be honourable such that his parents need not be ashamed.
Now wondering of topic, on Sunday morning I watch 5 religious programs, the hour of power, The Wold Tomorrow, Tomorrow's World, a SDA program, the name escapes me, Michael Yousef, and Dr Stanley. Each week I choose a winner; Dr Stanley won last Sunday, and Wallace Smith the week before; a couple of years ago there was a program on “Not Worshipping Paul”.
While I frequently misunderstand people and as one brother to another, that you may give consideration to it, what I see in your post is: You elevate Paul to the position reserved for Christ, you assign worship to Paul that belongs to God, and you give credit to Paul that belongs to God. This is a terrible thing to say, but I feel obligated to say it , expecting my effort to be invain.
