The Voice of the Shepherd

The Gospel for Tuesday in Whitsun Week (St. John 10:1-10) provides us with two ways for the sheep to be safeguarded against false shepherds.  The first is that their shepherd must go through the door.  That is, he must be properly and divinely called and ordained to preach.  The second is that his voice must be that of the Good Shepherd.  That is, he must preach the Gospel of Jesus and his mercy and forgiveness.  The sermon.
