During his quarrel with Philip the Fair of France charges were sworn on oath against Pope Boniface that he neither believed in the Trinity nor in the life to come, that he said the Virgin Mary "was no more a virgin than my mother"; that he did not observe the fasts of the Church, and that he spoke of the cardinals, monks, and friars as hypocrites. It was in evidence that the Pope had said "God may do the worst with me that he pleases in the future life; I believe as every educated man does, the vulgar believe otherwise. We have to speak as they do, but we must believe and think with the few." Died 11 Oct. 1303. Bonnycastle (John), mathematician, b. Whitchurch, Bucks, about 1750.
