It was time for Father John's Saturday night bath, and young nun Sister Magdalene had prepared the bath water and towels just the way the Mother Superior had instructed. Sister Magdalene was also instructed not to look at Father John's nakedness if she could help it, and to do whatever he told her to do, and pray.
The next morning the Mother Superior asked Sister Magdalene how the Saturday night bath had gone. "Oh, sister," said the young nun dreamily,
"I've been saved."
"Saved? And how did that fine thing come about?" asked the Mother Superior.
"Well, when Father John was soaking in the tub, he asked me to wash him, and while I was washing him he guided my hand down between his legs where he said the Lord keeps the Key to Heaven."
"Did he now?" said the Mother Superior evenly.
Sister Magdalene continued, "And Father John said that if the Key to Heaven fit my lock, the portals of Heaven would be opened to me and I would be assured of salvation and eternal peace. And then Father John guided his Key to Heaven into my lock."
"Is that a fact?" said the Mother Superior even more evenly.
"At first it hurt terribly, but Father John said the pathway to salvation was often painful and that the glory of God would soon swell my heart with ecstasy. And it did, it felt so good being saved."
"That wicked old Devil!" said the Mother Superior. "He told me it was Gabriel's Horn, and I've been blowing it for 30 years!"
