Answer: Correct Answer: The Assumption of Mary
Pope Pius XII defined the doctrine of the Assumption of Mary on November 1, 1950, through the apostolic constitution Munificentissimus Deus. This doctrine states that the Virgin Mary, "having completed the course of her earthly life, was assumed body and soul into heavenly glory." It was declared as an infallible dogma of the Catholic Church, emphasizing Mary's unique role in salvation history and her close relationship with Christ. This marked the first time a pope used the principle of papal infallibility to define a doctrine since it was formalized at the First Vatican Council in 1870. |
