That is completely beside the point, since the phrase "shall not respect/disprespect" does not appear in the first amendment.
It is "Congress shall make no law respecting an establishment of religion". In this sentence "respecting an establishment of religion" refers to the law, not the Congress. A law can do many things, but it cannot respect in the sense that you meant it. It can only respect as in pertain to, as regards, concern, etc.
Basically, Congress----->no law----->establishment of religion. It's so easy when you stick with the original meaning and not try to make it mean something else two centuries later.
Basically, Congress----->no law----->establishment of religion
Of course things are never apprached so simply in law. If they were, there would be no lawyers!
Even still, the above distillation you laid out reaches the same conclusion: Congressional endorsements of the God of Abraham are in direct conflict with the Establishment Clause.
