In other words, while a person of any denomination may be subject to threats or blackmail to change their position on something or risk getting kicked out, are catholic politicians or judges more of a concern because the church is a foreign government as well?
As long as Judge Roberts is a strict Constitutionalist as promised by the President, I don't see how being a Catholic in any way changes the main objective which is: someone who can interpret the law as it was intended by our Founder Fathers, considering that most of them were devoted Christians.
What GW wants, is a Judge who applies the law consistent with the original intentions of the Founders, and doesn't rule from the bench disregarding the rule of law, and abusing his/her power by entrenching the rights, stability, and protection of ordinary citizens as most Liberal Judges do.
Even though the Catholic Church doesn't interfere in judicial reviews or government's decisions, the hostility against Catholics is patently clear.
Yet to this day, the truth still remains as George Washington expressed in his farewell address:
"Of all the dispositions and habits which lead to political prosperity, Religion and Morality are indispensable supports. In vain would that man claim the tribute of Patriotism who should labor to subvert these great pillars of human happiness, these firmest props of the duties of Men and Citizens. ... And let us with caution indulge the supposition that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle."
Judge Robert Borke was on C-Span yesterday and was asked if there would be a conflict with Roberts and his Catholic faith. Borke responded that no where in the Catholic faith does it re-evaluate constitutional law. If anything things become un-constitutional when basic rights are denied.
Roe Vs. Wade would be a prime example.
