No, not Jack from Lost, Matthew Fox the theologian. Fox has had some interesting things to say about men and spirituality, some of which I like and some which leave me with some concerns. Here are a couple of links to items I have written about Fox:
A conversation between Fox and myself in Ashe Journal which speaks in part to the theme of men and spirituality.
A review from Journal of Men, Masculinities and Spirituality of his latest book, The Hidden Spirituality of Men.
