This is not a call for quietism, as the Church states in the Catechism (2234-2243). Section 2242 sets out in black and white the limits of what any state can command from its Catholic citizenry. However, the Magisterium is equally clear that we have to listen to what Wordsworth memorably called the "Stern Daughter of the Voice of God" -- duty:
It is the duty of citizens to contribute along with the civil authorities to the good of society in a spirit of truth, justice, solidarity, and freedom. The love and service of one's country follow from the duty of gratitude and belong to the order of charity. Submission to legitimate authorities and service of the common good require citizens to fulfill their roles in the life of the political community (2239).
Please note that the emphasis here is in the original. As you can see, corrosive partisanship is not on the list of duties. As Catholics, we are held to a higher standard, and we need to meet it. Given how polluted the public square is these days, we have no choice.
Finally, if Scripture and Tradition are leaving you particularly unmoved today, let me offer pragmatism: Shrill, bitter, and paranoid is no way to go through life, son. Nor are they a blueprint for a reversal of electoral fortune. Obama did not campaign on a mantra of bitter, vindictive gloom, and there is a simple reason for it: Nobody wants to be in the same room with a guy who spews this kind of talk, let alone vote for him.
Obama is our next president, like it or not. Our marching orders are clear: Pray for him and our country, work with him where possible to achieve the common good, and fight like a Maccabee when he oversteps his bounds -- all the while remembering that November 2010 and 2012 will be here quicker than we think.
In my heart, I know that I should not be bitter or resentful. Yet I don’t even want to open the newspaper or turn on the television because the sight of Barack Obama turns my stomach. His agenda is unspeakably evil and the country I love elected him as our next president. I feel hurt and betrayed. There were not a lot of campaign yard signs in my neighborhood but there was a sprinkling of signs for both McCain and Obama. I haven’t yet spoken with neighbors I know supported Obama. I really do not want to. It feels like a chasm between us. You know I can civilly argue and discuss foreign policy, economic policy, or health care and agree to disagree. On the other hand, my response to the support as a common good the slaughter of unborn children is both visceral and primal. The human person exists at the moment of conception and is entitled to intrinsic dignity and respect from that moment to the moment of natural death. I can’t compromise on this. It is the truth. Period.
If it were up to me and my fallen nature, reconciliation with Obama supporters would be hopeless. The good news is that is not up to me. There is God’s grace. Through prayer and through the Sacraments, I will be able to love my enemies. It is going to take some time. And loving my enemies does not mean I will ever love or accept their actions. But hate will never lead to the conversion of their hearts. For the sake of the vulnerable, I must love. And then maybe, as in today’s Gospel, the lost sheep will be found and all will rejoice.
