The story is told about the baptism of King Aengus by St. Patrick in the middle of the fifth century.  Sometime during the rite, St. Patrick leaned on his sharp-pointed staff, inadvertently stabbing the king's foot.  After the baptism was over, St. Patrick looked down at all the blood, realized what he had done, and begged the king's forgiveness. “Why did you suffer this pain in silence?”, the Saint wanted to know.  The king replied, "I thought it was part of the ritual."

C.S. Lewis wrote:- ‘Pain is not good in itself. What is good in any painful experience is, for the sufferer, his submission to the will of God, and, for the spectators, the compassion aroused and the acts of mercy to which it leads.’
