My friend, Prior Peter, of Holy Cross Monastery in Chicago has recently posted 2 interesting posts concerning "God or Subjective Concept?" You can read both here and here. They are worth a read.
Coincidentally, if you live in the Metro Chicago area and ever need an well made and affordable casket for a loved one, do check out their monastery caskets. They have a wonderful ministry doing that, particularly for poorer folks who can't afford several thousand dollars for a casket.
