Readers today are reminded of the infalliable Marian doctrines. Remember that Christians have long held in faith the witness of grace in the Immaculate Conception and the Dormition/Assumption of Mary. These were not theological insights dropped from heaven in 1854 and 1950.
But since it has pleased God not to manifest solemnly the mystery of the salvation of the human race before He would pour forth the Spirit promised by Christ, we see the apostles before the day of Pentecost “persevering with one mind in prayer with the women and Mary the Mother of Jesus, and with His brethren”,(Acts 1, 14.) and Mary by her prayers imploring the gift of the Spirit, who had already overshadowed her in the Annunciation. Finally, the Immaculate Virgin, preserved free from all guilt of original sin,(Cfr. Pius IX, Bulla Ineffabilis 8 dec. 1854: acta Pii IX, I, I, p. 616; Denz. 1641 (2803).) on the completion of her earthly sojourn, was taken up body and soul into heavenly glory,(Cfr. Pius XII, Const. Apost. Munificensissimus, 1 no. 1950: AAS 42 (1950) ú Denz. 2333 (3903). Cfr. S. Io. Damascenus, Enc. in dorm. Dei gcnitricis, Hom. 2 et 3: PG 96, 721-761, speciatim col. 728 B. – S. Germanus Constantinop., in S. Dei gen. dorm. Serm. 1: PG 98 (6), 340-348; Serm. 3: col. 361. – S. Modestus Hier., In dorm. SS. Deiparae: PG 86 (2), 3277-3312.) and exalted by the Lord as Queen of the universe, that she might be the more fully confimed to her Son, the Lord of lords(Cf Apoc. 19. 16) and the conqueror of sin and death.(Cfr. Pius XII Litt. Encycl. Ad coeli Reginam, 11 Oct. 1954: AAS 46 (1954), pp. 633-636; Denz. 3913 ss. Cfr. S. Andreas Cret., Hom. 3 in dorm. SS. Deiparae: PG 97, 1089-1109. – S. Io.
