To follow on my use of the corporal work of mercy bury the dead as it regards our lady, according to the thinking of those who say she died and was buried, we should likewise pray for mercy to be had on her as we would pray for the living and the dead. But, that is clearly absurd. Mary is ever virgin. Mary is spouse of the Holy Ghost. Is there even a prayer "for Mary" found in tradition? Why would there be a separation in corporal and spiritual matters in this regard? It is obvious and simple. Mary was not buried. If she was not buried, she did not die. "Full triumph over sin and its consequences(death)" is in the assumption definition itself.
In fact there is a very conspicuous prayer "for Mary" if you broaden your search beyond recent-century Roman-rite speculation. The anaphora (the analogue of the Roman Canon) of the Divine Liturgy of Saint John Chrysostom prays explicitly
for the Virgin and all the saints:
"Moreover, we offer you this spiritual sacrifice for those departed in faith: the forefathers, fathers, patriarchs, prophets, apostles, preachers, evangelists, martyrs, confessors, ascetics, and for every just spirit brought to perfection in faith,
especially for our most holy, most pure, most blessed and glorious Lady, the Theotokos and Ever-Virgin Mary."
Note that this includes the Virgin among those "departed in faith."
