"This government was formed by Christians, for Christians, and, for the perpetuation of Christianity."
By "this government" you surely must mean the Texas State government, right? I mean, you'd almost have to--not that you'd be correct--because only a complete and utter fool would say that about the U.S. federal government. I guess I should say it: Treaty of Tripoli, bitch.
"This nation's founders were so confortable in their Christianity, that they formed an open government that contained no litmus tests concerning religion."
You realize, of course, that most of the founding members of our country were, shall we say, less than Christian. Washington never attended Church with his wife and Jefferson published his own version of the Bible which removed all of the supernatural elements. In other words, when Jesus died he stayed that way. You can't get much more non-Christian than that. Adams, Franklin and Paine (especially Paine) were outspoken critics of the Church. Very few of the men considered to be a founder of this nation, directly or indirectly, could be considered "comfortable in their Christianity."
There is no "litmus test" concerning religion because it would have gone against the very idea of religious freedom. However, certain states do have such tests. Texas being one of them as a matter of fact. None, to my knowledge, are actually enforced though.
"Many of them stated openly that they didn't think it would be wise to elect anyone to public office but a Christian."
I'm not sure I'd use the term "many."
"They were so confidant and comfortable in their religious views that they did not fear other religions coming to America because they actually believed that Christianity was so superior, that , Christians would win them over."
Yeah, sure. I don't think that's quite why they didn't fear it.
