I wonder if somebody could help me find ancient references to a belief that Mary did not die. In researching this subject, I have tried to understand where this belief comes from. As an Eastern Catholic, it is something that I have never had cause to doubt, as her death is so strong in our tradition; It is taught in our liturgy and it is shown in our iconography. On the Feast of the Dormition, we venerate this icon, which shows Mary, lying in a tomb, with Jesus standing above the grave, holding her soul.
I have only learned in the last few years that there is any controversy surrounding this teaching. (I do call it a teaching of the Church, though I understand that it has not been dogmatically proclaimed. I contend that the Church does not teach error in her liturgy.)
I have been involved in a number of these discussions in the Catholic Answers Forums over the last few years and I have attempted to find the earliest evidence of teaching that Mary did not die. I have not found a single Church Father, doctor of the church or Pope that teaches that she did not die. I have not actually found anything historical. In fact, the only reference that I have been able to find is the statement that Pope Pius XII deliberately left it an open question (in spite of the fact that he referenced her death several times in the document.) My question is, who (among the saints or great theologians of the past) has taught that Mary did not die? Where are the quotes and documents? Where did this controversy come from? I know they must exist because controversy like this did not come out of nowhere. I have only seen evidence of this belief in Western art.
It is clear where the belief in her death comes from, but the origin of the belief that she did not die is less clear. Can somebody help with this?
