Taking your statements slightly out of order, you say, "The phrasing of the First Amendment was to prevent Congress from choosing any religion." I completely agree. It does not require it to decide to support any particular religion, but religion in general (otherwise they would have said so). As Jefferson stated, it was not picking one religion over another (although that is prohibited too), but simply promoting religion. (I can go into detail as to why chaplains and such are not prohibited, but I don't think that is necessary here.)

"In regards to the First Amendment the word establishment only means to fund a religion with taxes." I don't find support for that anywhere. Perhaps you can provide a citation to something? Again, yes, that would be expressly prohibited, but it is hard to reconcile that view with either the language of the Constitution itself or its interpretation for about 200+ years. Indeed, I can give a few examples of "Establishment" that do not require expenditure of funds, some of which I mentioned earlier but you did not address.
