All history and theology and whatever else aside, I find the veneration of the Blessed Mother’s tomb to be one of the delightful ironies of Catholicism given the emphasis some circles place on the absence of her bodily remains.
Perhaps understanding of such things is tied to a truly Catholic understanding of death, and I am far from that.
I was once watching a documentary on tv about artists throughout time who got in trouble with the church for painting scenes of the death of the Virgin Mary due to the belief that she never actually had a death.
I had no idea there was even a tomb of Mary.
