While it is frequently misused, the wealth of information and inspiration available on the web is amazing. For Catholics especially, sites like those maintained by EWTN have something for all levels of interest.
There was a powerful homily this past Sunday [Jan 18] by Fr. Anthony on EWTN. His homily draws a contrast between Martin Luther King day, Obama’s inauguration and the Pro-Life march in Washington which will follow. The homily is available in the EWTN Audio Library. The most powerful portion of the homily begins about halfway through the audio recording.
