Pope Pius XII proclamation on the Dogma of Mary's Assumption in 1950 ([*Munificentissimus Deus*](http://w2.vatican.va/content/pius-xii/en/apost_constitutions/documents/hf_p-xii_apc_19501101_munificentissimus-deus.html)) was silent on how Mary's death description was.

Eastern Orthodox believed in dormition.

There are also some who believed that the death & assumption occurs simultaneously.

However, [Blessed Catherine Emmerich's visions and revelation](https://isidore.co/calibre/#panel=book_details&book_id=4146) provide a good theme for filling in the light needed to harmonize the teaching of Catholicism and Eastern Orthodoxy.

My question is based on Blessed Catherine writings: **How does her narration harmonize the missing description of the Church when it proclaimed the 4th Marian dogma of the Assumption?** (as Pope Pius XII left description of death unclear).
