You remember that story about the Left Hand of Darkness's people ordering the cover up of the IHS insignia at Georgetown University in case the message was confused with I Hate Sinners.  Today (20th) is the feast of St Bernardine of Siena, the man who invented the IHS sign.  Of course it means Iesus hominum Salvator (Jesus Savior of Mankind).  Interestingly, in the light of the Georgetown incident, St Bernardine had it painted on a board and he used to hold it up in the pulpit.  For this he was accused of superstition and investigated by a group of theologians.  Of course he was exonerated.  He had a special devotion to the Holy Name of Jesus.
