Early in the movie, it’s clear Clavius is a pluralist. He’s a typical Roman—there are many gods and it’s subjective which ones you pray to. Even Yahweh is one more in the pantheon, no more true or superior to the others. But what Clavius confronts in the evidence he finds is objective truth. It calls for abandoning all the other gods and following the true way. This is very similar to our own culture now. Kind of amazing that we have so much in common with the Romans. This is the Christian message—a claim about reality and truth.
