I think there is confusion between a devout Catholic who is tolerant of other faiths and homsexuals (which is good) and a 'devout Catholic' who is "socially liberal".

Liberals in the US are not libertarians, but (warning: incoming generalization) lefties who support gay marriage, abortion, etc.

As for the article, I must agree with the X-man. It appears to me to be written by a more liberal Christian who tries to use our inability to fully comprehend God as an excuse to weaken any moral guidelines. And while I would not Catholicism to be tied down to any one party, I do not think a party with one religion as its centerpoint is any worse than a party that does not use religious morals as a guideline, assuming they don't try to force people to go to thier church.

All the people wailing against religious parties need to remember that in politics, religion is just the source of the morals, the party platform. All parties have a platform based on what they believe, and the platform coming from religion does not make it inherently worse.
