Immaculate Conception
From BiblePortal Wikipedia
The Nuttall Encyclopedia [1]
The doctrine held by the Roman Catholic Church that the Virgin Mary was conceived and born without taint of sin; first distinctly propounded in the 12th century, at which time a festival was introduced in celebration of it, and which became matter of dispute in the 14th century, and it was only in 1854 that it became by a bull an article of the Catholic faith.
