I don't have any "trouble" with those words not being in the constitution! I'm just fine with the wording the founding fathers used in the constitution, and the exclusion of those words. Evidently you are not.
"You can use any dictionary to find the meanings of all those words." Normally theret is a choice of meanings in the dictionary listings. The choice you select is usually dependent on the context in which the word is used. I can tell you what I believe the meaning of those words is, even if you are reluctant to tell me your interpretation:
"Support" would mean the same as facilitate, promote, or sponsor in any way. But I believe the government does support religion, if you use those definitions. You would have to say the tax exempt status granted religions and churches is definitely "support", wouldn't you? So I don't the Constituion prohibits all "support". If it does, we don't follow the Constitution, do we?
"Religion" in the current context of our discussion, means to me: Any particular denomination (such as Methodist, Roman Catholic, Hasitic Judahism, Sunni Muslim, etc.). It does not mean Christianity or any general set of Western Culture Morality. So the Constitution does not prohibit the promotion of Christian principles and morality. In fact they were used in the construction of the basis for legal system.
"Involved in government"? I really don't know what you mean, or would I adopt that principle nor would I have a meaning for it. There is no prohibition against religions getting involved in government. Churches cannot promote particular political parties without risking the loss of their tax exempt status, but they certainly are not prohibited from doing it as a matter of law.
Now do you understand why I was interested in what you specifically meant by the words you used?
