This document infallibly defined, for now and forever, the dogma that “the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory”.
Mary, having been conceived immaculately, was spared the pain of original sin and never succumbed to actual sin. As such, she never received the wages of sin, that is, the corruption of the body at death. No, being so perfect, more perfect than any other human person, she entered heaven in full bodily glory. Today is the solemnity of the Assumption of the Blessed Virgin Mary.
