"I'd guess that most of you have never heard of this concept. Don't worry. I wouldn't expect it. Popular at one point, there are now very few churches that subscribe to it and, as you would expect, the rest have mostly put it out of their minds. So ... what is it? You've heard, I assume, of the principle of Christian Liberty. Based on passages like Romans 14 and1 Corinthians 10:23-33, this principle holds that Christians are permitted to do anything that God's Word does not forbid within the confines of conscience. Now, that's an oversimplification, perhaps, and there are lots of considerations, but that's the idea. Well, the regulative principle of worship is like that, except in reverse. This principle says that in worship believers are only permitted to do that which God commands.
The idea, believe it or not, comes from Scripture. The most compelling clue comes from the story of Nadab and Abihu. These priests, sons of Aaron, offered "strange fire" and were instantly burned to death (Lev 10:1-2). For "strange fire"? Oh, sure, the ESV says "unauthorized fire", like that helps. The point is that they didn't violate a command from God; they simply did something in worship that He had not commanded. When Aaron started to complain, Moses told him, "This is what the LORD has said: 'Among those who are near Me I will be sanctified, and before all the people I will be glorified.'" And the text says that with that, "Aaron held his peace." (Lev 10:3)
It looks then like God is concerned with specifics in the worship He receives. Thus, Moses was not allowed to make whatever he thought appropriate for the tabernacle. He had to make everything "after the pattern for them, which is being shown you on the mountain." (Exo 25:40) The first two commands of the Decalogue are about the proper worship of God (Exo 20:1-6). Paul warns about "self-made religion" which "have indeed an appearance of wisdom" but "are of no value in stopping the indulgence of the flesh." (Col 2:23) Jesus rejected "the traditions of the elders" (Matt 15:1-13) and required a return to "the commandment of God". So it looks like the regulative principle of worship may have a biblical case.
After that, of course, the case breaks down..."
I will point out that my response is not, of course, an attack on Stan, but on this human (and nutty-sounding) theory... The "Regulative Principle of Worship..." Also, I will note that Stan does not fully endorse the claim. He merely says he thinks "the case for the regulative principle of worship has merit."
Here we have a "principle" that Jesus never advocated being proposed as a serious Christian tenet. The case is built almost entirely on one obscure passage from the OT, and even there, it does not promote this as a principle, but humans have taken the passage and fabricated out of thin air a principle they extrapolated from this obscure passage something that even Stan notes is the reverse of a more reasonable and consistently biblical theory, the idea of Christian Liberty.
[I will note here that I find Stan's description of Christian Liberty interesting, as taken literally, it would destroy his arguments against gay folk marrying, since God's Word never "forbids" it... it is a human extrapolation. So, presumably if one is going to be consistent on the notion of Christian Liberty, one would embrace grace on the topic of gay folk marrying or transgender folk going to the bathroom in the reasonably appropriate place, rather than the legalism of modern fundamentalist/conservatives.]
Using this approach, all manner of evil and craziness could be promoted as "coming from Scripture."
"There's this line in the Bible where God clearly okays the selling of one's daughters into forced marriages. This comes from Scripture and, thus God..."
"I just read about how God told the Israelites to slaughter all the people of a nation when they invade, so that is how God wants us to deal with our enemies, it comes from Scripture..."
This is the problem with the legalistic approach to using/misusing/abusing the Bible... Merely finding a passage and then, extrapolating OUT FROM that passage a human theory about what God wants (even when God never said so) is a potentially horrible idea. However, as long as you are fine with admitting it is your theory and NOT "God's Word," then okay, so perhaps it lets you extrapolate out bad or irrational theories, but it is clearly your theory and you gladly and humbly admit as much. We might could live with that. But the problem is when one conflates the extrapolated human theory with God's Word.
"It comes from Scripture..."
If it doesn't mesh with the teachings of Jesus, don't offer up an extrapolated theory as being a reasonable Christian tenet. If it sounds crazy and legalistic on the face of it, don't offer it up as a reasonable teaching of Jesus. If JESUS didn't say it, don't say it's a teaching of Jesus.
The idea, believe it or not, comes from a HUMAN head, not from God. It is something that humans are extrapolating out and imposing upon God when God has not said it. That is a bad idea. It is irrational and presumptuous and, quite possibly, even evil. Don't do that.
The one line Stan (and presumably others who might agree) got right is, "the case breaks down."
Indeed, the case breaks down when you move from an amusing "what if this were taken THAT way...?" party game about human theories and the Bible and move to "I've decided this is biblical and thus, what God wants. HEED MY WORD."
Bad, bad idea.
