Of course, the faithful abide no symbol of state power set before the eyes of the congregation in our houses of worship, anyway. The very presence of the state sigil is, by the nature of the thing, a proclamation of magisterial dominion; and by way of the fact that the state has no lawful claim of sovereignty over the ecclesiastic sphere, the symbols thereof have no legitimacy in the context of the church. This is why churches were historically exempt from state taxation – because Christ’s command was to render unto Caesar only that which belonged to Caesar, and Caesar had no claim within the church threshold (nor even in any Christian home, a la the Castle Doctrine); so it was that the church retained rights of asylum (as cities of refuge) by which they might shelter men against the abuses of the state. This concept is integral to the doctrines of sphere sovereignty and interposition, and our fathers, in their wisdom, maintained that though Christianity is necessary to lawful civil government just as much as to the church, the civil government has no more lawful authority to impose itself upon the church than the church has to usurp the power of the state, or that of the family, for that matter. These are the countervailing checks and balances of the Christian society, the purpose of which is to mitigate the excesses and abuses to which men tend in their sin.
