George, a Catholic, has influenced Protestant and observant Jewish scholars and religious leaders, as well as Catholics. Under the auspices of the Institute on Religion and Public Life, he has worked closely with such figures as Fr. Richard John Neuhaus and Rabbi David Novak. His natural law arguments for traditional moral principles have frequently been invoked by Evangelical Christian figures such as James Dobson and Charles Colson. (See, for instance, his impact on Chuck Colson and Nancy Pearcey in their book How Now Shall We Live?)
He sounds okay to me.
