John Cuthbert Hedley, 1911 Encyclopædia Britannica (1911)
“ These words presuppose the distinction between original, or racial, and actual, or personally incurred sin. There is no dispute that the Church has always held the Blessed Virgin to be sinless, in the sense of actual or personal sin. The question of the Immaculate Conception regards original or racial sin only. It is admitted that the doctrine as defined by Pius IX. was not explicitly mooted before the 12th century. ”
