Charles Spurgeon and Joseph Parker both had churches in London in the 19th century. On one occasion, Parker commented on the poor condition of children admitted to Spurgeon's orphanage. It was reported to Spurgeon however, that Parker had criticized the orphanage itself. Spurgeon blasted Parker the next week from the pulpit. The attack was printed in the newspapers and became the talk of the town. People flocked to Parker's church the next Sunday to hear his rebuttal.

Here's his response: "I understand Dr. Spurgeon is not in his pulpit today, and this is the Sunday they use to take an offering for the orphanage. I suggest we take a love offering here instead." The crowd was delighted. The ushers had to empty the collection plates 3 times. Later that week there was a knock at Parker's study. It was Spurgeon. "You know Parker, you have practiced grace on me. You have given me not what I deserved, you have given me what I needed.
