Here are a few places you can visit should you want to learn more about the Catholic perspective:
The Catholic Thing and The Faith & Reason Institute.
It looks like those sites provide some interesting articles about politics and other issues that intertwine with faith for better or worse. Browse at your own risk, though; I have not looked enough to know if they are trustworthy.
Since I identify with the Protestant branch of Christianity (though I was born of Catholic heritage), it’s all too easy to forget about how Catholics perceive culture and politics.
On the topic of politics, sometimes it’s daunting trying to keep abreast with all the issues and discerning who tells the truth and whose truth is best. I invite you to leave any links regarding politics and/or religion (of any form) in the comments. May we all stay informed and vote wisely this November.
