Father Raniero Cantalamessa, Preacher to the Papal Household, is a dynamic and powerful homilist. I always look forward to his Lenten offerings. Very commanding speaker.
Still, my favorite Catholic Preacher remains Father George Rutler. Everytime I listen to him I feel as though I have been edified (spiritually and intellectually), and I always long to hear more. He is the personification of clarity, in my view. I wish EWTN would offer some current programming featuring Father Rutler.
