You may have heard of the James ossuary discovery, an ossuary that has written on it "James the brother of Jesus" The Israeli Antiquities Agency (IAA) considers the ossuary of James to be a forgery.
However, 6 other ossuaries in the tomb (out of 9-10 total) are considered to be authentic:
Jesus son of Joseph
Judah son of Jesus
One question such a claim leads to is whether there are any records, even in gnostic or apocryphal gospels, that say Jesus had a son named Judah?
A second question would be- how obvious would the tomb have been in 1st-2nd Century Judea?
Could someone have happened to walk by and see a tomb, and think, "Hmmm..., somebody's tomb. Whose is that?" Then they ask around and someone tells them it belongs to Maria's family.So it just happened that in almost 2000 years, no outside party, happened to see inside a tomb, known to belong to Jesus' family, that there was a "Jesus" ossuary inside?
The Judaic authorities were so anti-Christian when they ruled Judea in 30-135 AD that the Judaic council of Jamnia pronounced a curse on them 3 times a day at services. St Jerome records such a curse still in effect in the 4th century against the Nazarenes "because they as Jews proclaim Jesus to be the Messiah" [to paraphrase]. The point is that if they were so anti-Christian, it seems that a group tomb belonging to Mary's family would be something they would really want to investigate.
The implications of the claim that the ossuary is Jesus Christ's ossuary are that Jesus' ascenscion and post-resurrection appearances were simply Midrashes (religious commentaries) on His survival of execution, even though the gospels clearly describe the appearances themselves in miraculous terms. Based on such a claim, one would expect that Jesus' body wouldn't be simply hid in a family tomb with everyone else. Assuming that the apostles just made the stuff up, you would think that they would at least try to hide the body better.
The gospels record that "the Jews" accused the Christians of hiding Jesus' body. If the Christians hid the body though, it strongly goes against putting it in a group tomb with 10 other bodies.Critical thinking needed.
