A number of people, including Nick Carbone and Clancy Ratliff have sent me a link to the article "From Homer to Hip Hop", a good introduction and summary of Fr. Ong's work that was published in the July/August 2004 issue of Christianity Today International. If you haven't yet read it, it's most definately worth a few minutes of your time.
This might also be a good time to mention the link to the homily at Fr. Ong's memorial mass, which was given by Fr. Padberg who was then rector of the SLU Jesuit community.
