So if you're going to cut and paste what you want "separation of church and state" to be...here's another view.
"On the other hand, there are those who believe the matter is simply that the government should not establish an official state church, or that a church should not be anointing officials in the government. Other than that, people should believe and practice how they see fit. Both sides couch their arguments on constitutional theories, some involving Thomas Jefferson's "Wall of Separation" letter.
To consider this issue, it is important to look at the historical situation of the framers and what they intended. To recap, they were declaring independence from the king of England. There is one important title for the monarch of England that is relevant to this issue—Supreme Governor of the Church of England." Not only was the Church of England the official state religion (and still is), but the king himself was the head of that church. This ensured that his political reach not only extended in the public realm, but from the pulpit. The hierarchy of the church was subservient to the king. This led to abuses in both directions—those by the church and those by the government.
The founders did not declare independence from England because they wanted to set up a secular state. They declared independence because of a long train of abuses and usurpations of government power against its people. They were concerned about matters of tyranny, not theology. The Boston Tea Party was about taxes (and thus enshrined in American tradition the fine art of complaining about taxes), not about Baptists throwing Presbyterians' Bibles into the Atlantic. The Declaration itself made liberal use of religion in general, as did the founders in their public statements. Even in Jefferson's "Wall" letter, he expresses religious sentiment and asks for prayers. It's obviously clear; it isn't religious expression they are worried about.
The choice of phrase is important, "separation of church and state." Jefferson doesn't say separation of religion and state. He is talking about institutional separation. Ireland's official church is the Roman Catholic Church, as is Poland's. In England, it's the Church of England. These aren't religions in general but specific religious institutions. No nation has "Christianity" as the official state religion for a very good reason. The reason is that there's about 50,000-some odd flavors that run the gamut from the Mormons to the Unitarians. Some Christians say Jesus established a hierarchical church, others say He was a social activist, still others say He was an anarchist. Saying Christianity is the official state religion would border on effective meaninglessness. It wasn't the ideas that the founders were afraid of, which is why they were perfectly free praying together and expressing religious sentiment in public documents and speeches. Institutional corruption and tyranny were their concerns.
The results of institutional mingling of churches and governments are quite clear in history and it hasn't been beneficial for the state or the church. However, this is a far cry from divining an intent that projects the idea that "religion is all that's wrong with the world" upon the founders. There was a camp among the founders who believed that a free society required a religious people and yet still continued to allow free association between the various churches."
