This is a list I made of all the sermons and conferences of Fr. Pfeiffer that have been transcripted by other Catholics, it also includes his letters. I thought that maybe some people would like to have a list of them. These sermons, conferences and letters can all be downloaded from the Catacombs.
I will update the list as I find more transcripts.
"The inner life of another that is known to God alone becomes to a much less degree open to us through friendship. It partially fills the desire of our incomplete, lonely hearts for completeness in another. Friendship brings out the best in a person through forgetfulness of self." - St. Thomas Aquinas
