Cong. Paul Ryan is a politician, not a theologian, and complaining that politicians are not theologically sound is a little like complaining that carrots are not purple. Seek joy where joy may be found.
In this instance, however, Cong. Ryan chose to justify his budget proposals as consistent with Catholic moral teaching. He could have said, as Churchill did, “The Sermon on the Mount is the last word in Christian ethics. Everyone respects the Quakers. Still, it is not on these terms that Ministers assume their responsibilities of guiding states.” Instead, Ryan asserted that, mindful of the principle of subsidiarity and his strange understanding of the “preferential option for the poor,” his economic proposals amounted to the Catholic baptism of Hayek and von Mises. The lion had lain down with the lamb.
