It isn’t what I think… it was why it was written.
First, notice the glaring reality that it doesn’t state “separation of church and state” - That statement cannot be found except in one single letter from Thomas Jefferson written to a Baptist assemble in Connecticut. The position of “freedom from religion” instead of “freedom of religion” is a modern day imposition of thought on people. It was a direct effort to not let what happened in England - to make a national church thus the context of the letter was to assure the Baptist that they didn’t have to worry about the governmental forcing of one sect over another.
The purpose of the “Establishment Clause” is two-fold: (1) to prohibit Congress from imposing a national religion upon the people; and (2) to prohibit Congress (and the Federal government generally) from interfering with existing church-state relations in the several States. Thus the “Establishment Clause” is linked directly to the “Free Exercise Clause.” It was designed to promote religious freedom by forbidding Congress to prefer one religious sect over other religious sects. It was also intended, however, to assure each State that its reserved powers included the power to decide for itself, under its own constitution or bill of rights, what kind of relationship it wanted with religious denominations in the State. Hence the importance of the word “respecting”: Congress shall make no law “respecting,” that is, touching or dealing with, the subject of religious establishment on a national level.
The modern effort to “abridge” this freedom is contrary to the purpose of what was written.
If you check every State Constitution, you will find God in all of them. If the purpose of the Constitution was to have no religion, it would have forced every State to amend their Constitution.
Every State Constitution is proof that today’s interpretation is in error.
