I notice in the UK press discussion of the idea of a "wealth tax".
The idea is that the rich should have their assets raided, to help the country out of an emergency.
This idea calls for theological and moral analysis. People who have earnt money paid tax on it when they earnt it. The government took what was supposed to be its portion at that point. It will also take a further portion when that money is spent, e.g. in sales taxes.
But government reaching into your pocket and deciding to take money, simply on the grounds that you own it, is a far-reaching idea. It means ultimately that you own nothing, and the state owns everything. If a "wealth tax" is even on the table for discussion, then it means that nothing is your own. Its all only on loan. You are a steward, but the state is the possessor. At any time the all powerful state can claim back exactly as much as it pleases, and re-assign it to other uses as it sees best.
That means that the state is God. Traditionally in British thinking, only God has those kind of rights. The earth is his (Psalm 24:1), and he lends it out to us, as stewards. He can claim it all back, through his providential interventions, or through withdrawing us from the earth, when he pleases. Governments had much more limited rights. They can levy taxes for their legitimate functions; but they do not have an absolutely ownership that allows them to treat what has already been taxed as up-for-grabs again, to take or allow you to continue with as they please, as and when the political winds change.
Secularism pushes out God from the public square. That's its goal. But it's not possible for man to be god-less. Something else has to take God's place. The counterfeit God is the state. The state owns everything. If you own too much land or money, it simply decrees by fiat that it is taking it back from you again. Thought you earned it? Wrong - it was only on loan. If a people won't let God rule it, then they can't escape being ruled; hat's not possible. They will be ruled - but by someone or something far worse. Your judgment is to be ruled, not
mercifully, but by arbitrary despots who do not recognise your ultimate right to possess anything at all. A politician may wake up tomorrow and decide that all you has is now the state's again. When God is no longer God, the result is man's tyranny.
