By the end of "Raiders of the Lost Ark," archaeologist Indiana Jones had learned enough to know that he should close his eyes when facing the wrath of God.

Apparently, that kind of power can melt Nazis -- without changing the hero's soul.

"Why won't Indiana Jones convert? We aren't insisting that he convert to our faith or to his father's faith or really to any faith in particular," noted Jack Bennett, in a Popcorn Cathedral video marking the "Indiana Jones and the Dial of Destiny" release.

"What we want to know is why he is always back to square one at the start of every adventure -- a skeptic, or even a scoffer. I mean, think about it: He has seen the Ark of the Covenant opened and the destroying angels pour out God's vengeance on his enemies. He has seen the sacred Hindu stones come to life. …He has seen the true cup of Christ heal his own father from a fatal gunshot wound -- on screen, with no ambiguity."

In what the 80-year-old Harrison Ford has promised is the finale, Indiana Jones remains the archaeologist who risks everything to keep supernatural, even holy, artifacts out of the bad guys' clutches.

This is a war between archetypes of Good and Evil -- with capital letters. The Nazis are on one side, fighting with a brave skeptic who careens through scenes based on Saturday-matinee classics. Miraculous stories from the past are mere fairy tales, until he learns that Higher Powers are at work. Then again, maybe it's just aliens or generic supernatural forces.

In the new film, Jones confesses: "I don't believe in magic, but a few times in my life I've seen things, things I can't explain." But after a life wrestling with sacred mysteries, he concludes: "It's not so much what you believe. It's about how hard you believe it."

This elderly Indy is "a failure, he's a loser, he's discouraged," noted critic Titus Techera, who leads the American Cinema Foundation. In a Law and Liberty essay, "Dial for Therapy," he argued that Jones has become a man who truly needs to be saved from himself.

"Indiana Jones is not a skeptic, now," said Techera, reached by telephone. "He has seen things that point to the importance of belief and even to the transcendent. But he has decided that it only matters that you believe -- not what you believe. …

“What other kind of resolution could there be? He believes, but not in anything that might represent some form of fanaticism to Hollywood. There is nothing that he can convert TO that would be acceptable. Where is Indy supposed to go?"

Nevertheless, there's no way to avoid religion in the Indiana Jones timeline, starting with "Indiana Jones and the Temple of Doom," a prequel to the original "Raiders of the Lost Ark," said Steven Greydanus of DecentFilms.com and the National Catholic Register. He is a permanent deacon in the Archdiocese of Newark.

After a dark polytheism plot in "Temple of Doom," the original trilogy embraced Judaism in "Lost Ark" and then Christian symbolism, with the Holy Grail, in "The Last Crusade," noted Greydanus, in an online essay covering the five-movie arc. There's no way to avoid the dominant "Third Reich versus God" framework.

Then there are "vague, New Agey aliens" in the 2008 "Kingdom of the Crystal Skull." Now, "Dial of Destiny" opens with another hint of Christianity -- seeking the Longinus "Spear of Destiny," which a Roman soldier used to pierce Jesus' side on the cross. But that artifact turns out to be fake and the plot centers on "Archimedes's Dial," a time-travel device yet another Nazi believes can change history.

It's interesting to note this "trajectory of spiritual images," said Greydanus, by telephone. "Indy sees the miraculous in the first movie they made. It's right there. But he is less and less interested -- movie after movie -- in the source of that transcendent power. What's that all about?"

In the end, said Techera, the "question is not whether or not there is a place for God in these kinds of movies. The question is whether there is a place in them for truly human characters. Is there a place for people who ask the kinds of ultimate questions that human beings have asked through the ages?"
