I’d never considered this particular quote from Monty Python and the Holy Grail in the context if the Trinity before, but it’s quite apt.
“First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shalt be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, nor either count thou two, excepting that thou then proceed to three. Five is right out.”
That’s some good trinitarian theology there.
(Thanks to Philip Jenkins for the idea – The Jesus Wars, p. 64.)
