Eve of all Hallows, and Reformation Day

Today is the Latin feast of the Eve of All Hallows (or Hallowe'en). Today also is the anniversary of the posting of the 95 Theses of Martin Luther upon the Wittenburg Cathedral door, as Child of God has reminded me in a recent comment. While I have taken the liberty of deleting that comment (as it was off-topic), he has done a great service which should not be ignored, or forgotten. The full text of the 95 theses may be found here, and a summary of the import of those theses may be found here.
