The '''Immaculate Conception''' is a [[Roman Catholic Church|Roman Catholic]] [[dogma]] which asserts that [[Theotokos|Mary, the mother of Jesus]], was preserved by [[God]] from the transmission of [[original sin]] at the time of her own conception. Specifically the doctrine says she was not afflicted by the privation of sanctifying [[grace]] which afflicts mankind, but was instead filled with grace by God, and furthermore lived a life completely free from [[sin]]. It is commonly confused with the doctrine of the [[virgin birth]], though the two doctrines deal with separate subjects.
