It is not contrary to Church teaching, it goes beyond it. If the Church believed that these issues were more important than the other great issues involved in the election, like the potential for future war, terrorism etc, I think she would have said so plainly. But instead the Church teaches in the CCC that it falls to the laity to “engage in temporal affairs and direct them to God’s will” (898). She has deliberately chosen to leave this decision in the hands of the American people.
What things like this Voter’s Guide do is cause confusion among the faithful by acting as if it were an official outlet of the Church, declaring “non-negotiable” issues as if it had any authority to do so. In fact someone earlier in this thread more or less suggested that not following the Voter’s Guide exactly is a reason, in and of itself, to go to confession. I completely agree that the issues in the Voter’s Guide are issues which should be at the forefront of all Catholic minds, but I do wish people would calm down and recognize that the Voter’s Guide is not a papal decree.
In fact, I bet you if the Republican party started to see that they need to do more to satisfy the Christian vote than just stick to anti-abortion, we might start to see candidates appear who accurately reflect Christian values more completely, who are both anti-pre-emptive war and anti-abortion. But right now they have no reason to change because they realize that they will always control the Christian vote with one issue. With that one issue they have the Christian vote, and they are free to pander to Lord knows who with all of the others. Heck that’s just smart politics on their part, and it works because we Christians aren’t looking at the larger picture. In fact we are starting to convince ourselves that it would sinful to do so.
