It is really this easy
“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.”
The First Amendment to the US Constitution (as well as the next nine) is a negative right against the government, not you. The First Amendment to the US Constitution prohibits the government from establishing a state religion or restricting your free access to religion. That is the full extent (or at least should be) of government involvement with religion.
Should the citizens of this representative republic understand the extent of the First Amendment and then DEMAND that their elected representatives do so also, there would not be a problem with religion.
Should the citizens of this representative republic (and their elected representatives) understand that this constitutional restriction may not be altered by any amount of coercion, bribery, lobbying, promises, deals, favors, interference, or promises; there would not be a problem with religion.
Should the people who participate in religion understand that they cannot simultaneously participate in politics; there would not be a problem with religion.
Should the people who participate in politics understand that they cannot simultaneously participate in religion; there would not be a problem with religion.
Thus, if you follow the US Constitution, you may (or may not) freely worship God. You may (or may not) freely give money to your religion. You may (or may not) freely give of your time to your faith. It is really this easy.
However, if you decide otherwise, if you want to muddle the waters that history clearly demarcates as a "VERY BAD IDEA", there will be a problem, not with religion, but with you, using religion as a cover for your actions and your thinly veiled attempts at seizing power, influence, money, or all of the above.
Support a (not the) separation of Church and State. Keep the money in different accounts. Govern one and not the other. Find solace and comfort with God or without.
It really is this easy.
