{{Main|Munificentissimus Deus|Assumption of Mary}}
On 1 November 1950, Pius XII invoked [[papal infallibility]] for the first time since 1854 by defining the dogma of the [[Assumption of Mary]], namely that she, "having completed the course of her earthly life, was assumed body and soul into heavenly glory".<ref>AAS, 1950, p. 753</ref> To date this is the last time full papal infallibility has been used. The dogma was preceded by the 1946 encyclical ''[[Deiparae Virginis Mariae]]'', which requested all Catholic bishops to express their opinion on a possible dogmatization. On 8 September 1953, the encyclical ''[[Fulgens corona]]'' announced a Marian year for 1954, the centennial of the Dogma of the [[Immaculate Conception]].<ref>AAS 1953, p. 577</ref> In the encyclical ''[[Ad caeli reginam]]'' he promulgated the [[Queenship of Mary]] feast.<ref>AAS 1954, p. 625</ref> ''[[Mystici Corporis Christi]]'' summarizes his [[mariology]].<ref name="EMCC-110">Pius XII, Enc. ''Mystici Corporis Christi'', p. 110</ref> On 15 August 1954, the Feast of the Assumption, he initiated the practice of leading the [[Angelus]] every Sunday before address to the crowd assembled at [[Castel Gandolfo]].<ref>{{cite news | access-date = 20 August 2017 | date = 15 August 2017 | work = La Stampa | url = http://www.lastampa.it/2015/08/15/esteri/vatican-insider/en/in-history-the-violence-of-the-arrogant-takes-its-toll-but-god-does-not-leave-us-YkQPgaLUqi8kCDQtE1nWfJ/pagina.html | title = In history the violence of the arrogant takes its toll, but God does not leave us | archive-date = 20 August 2017 | archive-url = https://web.archive.org/web/20170820162959/http://www.lastampa.it/2015/08/15/esteri/vatican-insider/en/in-history-the-violence-of-the-arrogant-takes-its-toll-but-god-does-not-leave-us-YkQPgaLUqi8kCDQtE1nWfJ/pagina.html | url-status = dead }}</ref>
