( POSSIBLE ) ARCHAEOLOGICAL EVIDENCE FOR THE EARLIEST EXTANT CHRISTIAN REFERENCE TO BELIEF IN THE RESURRECTION & THE USE OF THE ( TETRAGRAMMATON ) BY CHRISTIANS

A tomb in Jerusalem was discovered in 1973 when some apartment blocks were being prepared to be built. It was briefly (but not thoroughly) excavated in 1981, then resealed because of protests by Ultra-Orthodox Jews. It is dated as being typical of a Jewish tomb from somewhere between 20-70 C.E. Between 2009-2011 it was reexamined by means of a robotic camera and it was discovered that it is most likely to be a VERY EARLY CHRISTIAN TOMB.

What is so remarkable about that?

They found inscriptions (one possible, the other definite) with:

 GREEK TRANSLITERATIONS OF
