I don’t think I can ever answer your question, as I don’t really understand it. If you are asking whether or not the Vatican has ever tried to direct the US government to do anything directly, I’m not aware of any such example.
Don’t be afraid to question the humans in high positions in your church; that blind faith has caused a lot of problems for the Church recently (and as with ObamaCare, they were only rectified when the enormous price tag became apparent).
I did question the influence and came up with nothing on the Church Hierarchy influencing the Govt.
Can you?
Don’t be afraid of the answer.
