Some details...
Matthew 11:19 The Son of man came eating and drinking, and they say: Behold a man that is a glutton and a wine drinker, a friend of publicans and sinners. And wisdom is justified by her children.
They were thieves and hustlers.
If you think so, you convinced yourself. No one else suggested that, here. You see, you're perfectly entitled to take part in political issues, so long as you don't try to impose your religion on others. That's not what God wants, and it's contrary to the law. And you are obligated to obey the law, unless it's contrary to God's law. And oppressing people of other faiths, is not God's law.
I'm just taking Jesus at His word. You should, too.
Actually, He was there all the time. Even without government support. He neither needs nor wants that. That's not how He works. We'll have a theocracy when He decides to do that. Men who are eager to do for Him, that which He choses not to do, are not doing His will.
Well, let's see what a Christian has to say about that...
Because the establishment proposed by the Bill is not requisite for the support of the Christian Religion. To say that it is, is a contradiction to the Christian Religion itself, for every page of it disavows a dependence on the powers of this world: it is a contradiction to fact; for it is known that this Religion both existed and flourished, not only without the support of human laws, but in spite of every opposition from them, and not only during the period of miraculous aid, but long after it had been left to its own evidence and the ordinary care of Providence. Nay, it is a contradiction in terms; for a Religion not invented by human policy, must have pre-existed and been supported, before it was established by human policy. It is moreover to weaken in those who profess this Religion a pious confidence in its innate excellence and the patronage of its Author; and to foster in those who still reject it, a suspicion that its friends are too conscious of its fallacies to trust it to its own merits.
Because experience witnesseth that ecclesiastical establishments, instead of maintaining the purity and efficacy of Religion, have had a contrary operation. During almost fifteen centuries has the legal establishment of Christianity been on trial. What have been its fruits? More or less in all places, pride and indolence in the Clergy, ignorance and servility in the laity, in both, superstition, bigotry and persecution. Enquire of the Teachers of Christianity for the ages in which it appeared in its greatest lustre; those of every sect, point to the ages prior to its incorporation with Civil policy. Propose a restoration of this primitive State in which its Teachers depended on the voluntary rewards of their flocks, many of them predict its downfall. On which Side ought their testimony to have greatest weight, when for or when against their interest?
