A recent find by archaeologists during a tomb exploration in Jerusalem uncovered what could be the earliest archaeological evidence for Christianity in Jerusalem. One ossuary, an object similar to a coffin or sarcophagus, contains a four line Greek Inscription that refers to God “raising up” someone. An ossuary next to it depicts an inscription of an individual in the mouth of a large fish – perhaps a reference to the Biblical figure Jonah, akin to other examples of early Christian art.
The ossuaries have been sent to the Israeli State Collection and are waiting authentication. If the ossuaries prove to be authentic (there are many fakes, most famous the Jesus Ossuary and the James Brother of Jesus Ossuary), then they would represent (by centuries) the earliest evidence for Christianity. The objects would predate the gospels by centuries.
