Sacrifice, Law and the Catholic Faith: is secularity really the enemy? is the title of the 2006 Tablet Lecture by James Alison. You can read this lecture in full (except for the footnotes) here.
Another lecture sponsored by The Tablet nearly two years ago, on a related theme, was Rendering Unto Caesar – Catholicism, Politics, Law and Democracy by Aidan O’Neill QC. You can read that lecture in full here (and continued here), and also the other material preceding and following it, here.
