“Jesus’ mother, Mary, died and was buried in Ephesus, a city in modern day Turkey. So it’s not likely that a tomb found in Israel would refer to the same Mary.”
As a Catholic I was taught that Mary, ascended into Heaven. Would that not mean that she was not buried?
Unless you were improperly instructed, you were NEVER taught that the Blessed Mother ascended into Heaven, you would have been taught that she was ASSUMED. The Lord Ascended into Heaven of His own Power; the Holy Mother was assumed through God's Power, not her's.
Nevertheless, teachings on Assumption are silent as to whether the Blessed Virgin was buried and does not even speak to her death (though it is presumed that she did die a natural death). So, there is no conflict between her being buried and assumed, especially when you consider the practice of the day of immediately cleaning the body and then burying it upon death (burial was generally within a couple hours of death).
