> Let us now consider what a church is. A church, then, I take to be a voluntary society of men, joining themselves together of their own accord in order to the public worshipping of God in such manner as they judge acceptable to Him, and effectual to the salvation of their souls.
Where do you see "legally registered organization" in this defintion?
Of course, within existing legal doctrine, "separation of church and state" could only refer to legal technicalities. And that's the whole point I was making, that separation goes both ways. For you to redefine the idea behind separation of church and state in merely legal terms is itself a breach of that separation.
The idea of separation of Church and State came from the Reformation, and it was explicitly about separation of the legal entities. And they were legal entities - notably under Calvin the Genevan Consistory was the entity in charge of religious life and it was separated to the civil authorities.
You've misunderstood your own sources. The Lutheran doctrine of two kingdoms, according to which the church is not a legal entity but which exists in the spiritual kingdom, was a way to protect the church from the law and other secular authorities. This doctrine was then adopted by Calvinists, one way of which is the way that you're talking about.
> this has nothing to do with consent laws, which are entirely a matter for the state.
That's what I've been saying. And it has nothing to do with my point.
