Pertaining to the two videos (without the JW splice in the 2nd video) I linked to in my prior post there is an article at https://www.washingtonpost.com/lifestyle/style/filmmaker-says-jerusalem-tomb-houses-some-of-jesuss-earliest-followers/2012/04/05/gIQAjCioxS_story.html . It says in part the following.
'The Patio Tomb is similar in structure to the “Jesus Family Tomb.” It consists of small niches dug in limestone that contain ossuaries — small stone boxes designed to hold the bones of the deceased. The most significant discoveries are an inscription in Greek letters on one of the ossuaries and carvings on another.
James Tabor, a religious studies professor at the University of North Carolina at Charlotte who was part of Jacobovici’s team, says the inscription can be understood to mean “God, Jehovah, Raise up! Raise up!” He and Jacobovici interpret this as the earliest statement of faith in resurrection.'
It looks like the name of the full documentary is called 'The Resurrection Tomb Mystery"; see https://en.wikipedia.org/wiki/Resurrection_Tomb_Mystery . I hope to find and watch that full documentary.
Many years ago on cable TV (or maybe on PBS) I watched a documentary by Simcha Jacobovici in which Jacobovici said the physical body of Jesus was not resurrected and that his bones were place in an ossuary. In the documentary Jacobovici also said that he believed that the earliest Christians believed that Jesus was resurrected to life as a spirit being (in other words the same teaching in that regard as the WT). In the same documentary a Catholic cleric said the church concluded long ago that Jesus had a bodily resurrection instead of being resurrected as only a spirit.
In a different topic thread I mentioned the view that the early Christians were called Chrestians instead of Christians. A source I read about that view showed pictures of inscriptions in Greek letters, including of the name Yahweh/Jehovah, along with incantations for healing.
