"The Irreplaceable Peter" by Harvey Cox is here. An excerpt:
There are thousands of anecdotes about Peter Gomes. Many have begun circulating since his death. My favorite one illustrates just how comfortable Peter was in his own skin. One day, he told me, when he was in the Memorial Church office and the secretary was out to lunch, he impulsively answered the phone.
"Is this Memorial Church?" a women's voice inquired.
"Yes, madam, it certainly is," Peter answered.
"What time is the service this Sunday?" the caller asked.
"At eleven o'clock as always," he replied.
"And will that stout little colored man be preaching?" asked the caller.
"Yes, madam," Peter said, "I SHALL be preaching."
