In yesterday's post I linked to Bishop Paprocki's letter on voting. If you haven't read it yet, please do so. Today I learned that Archbishop John Myers (Archdiocese of Newark, NJ) released a pastoral letter to his archdiocese entitled "When Two Become One: A Pastoral Teaching on the Definition, Purpose and Sanctity of Marriage". I also recommend that to your reading.
Dr. Jeff Mirus of Catholic Culture released yesterday an article entitled "The Dangers of Voting Your Heart: An Intrinsically Moral Guide". I also recommend that you read it. A few weeks ago I posted on Voting and the Principle of Double Effect; therein I voiced (and, in my opinion, adequately substantiated) my belief that abstention from this presidential race is morally problematic.
Below is a video from Rosaryfilms that nicely sums up Catholic principles for voting in the United States. Click here if you cannot see embedded video.
