Most important to me & my family...August 15th is the Feast of the Assumption of the Blessed Virgin Mary. The Assumption was defined as a dogma of the Catholic faith in 1950 by Pope Pius XII. A dogma is an irrefutable belief of divine revelation by God and the church. The pope declared: “We pronounce, declare and define it to be a divinely revealed dogma that the immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul to heavenly glory.”
