Our Life in Christ has finished up the series on the Prayer of St. Ephrem the Syrian. Here are the mp3 links to each program dealing specifically with the prayer. I cannot recommend highly enough this entire series. It is the absolute best I have encountered not only from OLIC but from any other talk program of any kind.
Part I
Part II
Part III
Part IV
Part V
OK Clifton... now I have to go to confession!
Thanks for the compliments. Glory to God.
