No serious doubt attaches to the slab itself: it is a genuine ancient Greek inscription. The dispute is about meaning. One tradition of interpretation, popular among some who study Christian origins, treated the edict as evidence of Roman alarm at reports of Jesus' resurrection, a striking, if never proven, link. The counter-case turns on provenance and material.
In 2020, a team led by Kyle Harper analysed a small sample from the back of the slab and found its carbon-13 enrichment and oxygen-18 depletion matched the upper quarry of the island of Kos. On that basis the authors proposed the edict responded to the desecration of the tomb of Nikias, a first-century-BCE Koan tyrant, and predated any Christian context. The study, published in the Journal of Archaeological Science: Reports, does not settle every question, and some scholars continue to defend a later or eastern setting, but it substantially weakens the assumed connection to Nazareth and to Jesus. The honest status is a real object of debated religious relevance.
