Story : We will see whether he baptizes us or we circumcise him.
There was a Christian priest in ‘Akká who regularly attained the presence of ‘Abdu’l-Bahá. One day other Christians asked him, “What benefit have you gained from visiting ‘Abbás Effendi so frequently?” He replied, “Soon I will baptize ‘Abbás Effendi!” When this news reached His [‘Abdu’l-Bahá’s] blessed ears, He replied, “Very well. We will see whether he baptizes us or we circumcise him.”
It was not long thereafter that the priest fell ill. No matter what the doctors tried, it had no effect, and indeed he grew worse. Eventually it was decided that a team of doctors would consult on his condition. Those doctors decided to examine him and consulted on his situation and when they completed their examination, they prescribed that no remedy except circumcision would cure him. After they decided conclusively on this, they carried out the surgery.
‘Abdu’l-Bahá – may my life be a sacrifice unto His will – would smile and say, “I made that comment in humor.”
Subsequently, whenever that priest would come before Him, he was most embarrassed and would keep his head low. It became clear from this incident that the Manifestations of Truth do not jest with anyone, since their humor is also serious.
This story is narrated by both Habib Muayyad and Khalil Shahidi. I have taken this from With ‘Abdu’l-Bahá - Reminiscences of Khalíl Shahídí, translated by Ahang Rabbani
