The movie doesn’t leave it inconclusive for the audience to decide. The evidence for Jesus’ resurrection is about facts and reality, not subjective opinion. That’s a unique take for a movie about Jesus and, I think, one of the most significant things about this movie. It’s consistent with the Bible’s claims about the resurrection. It happened. He was physically resurrected, not a specter or spiritual presence. The reality and Clavius’ response to it aren’t left open for the audience to decide for themselves. It happened, and there’s ample rational evidence to believe that.
