It’s been 13 years since the first Harry Potter book landed on store shelves and provoked some Christian conservatives to begin voicing opposition to J.K. Rowling’s world of wizardry.

“Let me say something about Harry Potter. Warlocks are enemies of God,” said Becky Fischer, a Pentecostal pastor featured in a documentary called Jesus Camp. “And I don’t care what kind of hero they are, they’re an enemy of God."

“Had it been in the Old Testament,” Fischer continued, “Harry Potter would have been put to death. You don’t make heroes out of warlocks.”

First reviews of 'Harry Potter and the Deathly Hallows, Part 2'

I was a graduate student at Yale when I first heard words like these, and it made me want to delve deeper into the nexus of Harry and Christianity, to see whether the books really were heretical.

So I decided to pitch a class on the subject to Yale, where I continue to teach on the intersection between Christian Theology and Harry Potter.

One of the questions I get asked most frequently about the class is what makes the Harry Potter series so spiritually rich. My sense is that, unlike some other famously theologically driven books, like "The Chronicles of Narnia" or "The Lord of the Rings, Harry Potter" is less interested in teaching doctrine than in asking questions of ultimate meaning:

How can a person—wizard or Muggle (Rowling’s term for non-wizards)—respond to evil?

Is it possible to maintain relationships with those beyond the grave, just like Harry sought to have a relationship with his deceased parents?

Is it worth believing in God or, for those in Harry’s world, love, without evidence of its transformative power?

These are the questions to which Harry seeks answers throughout the series, most explicitly in "The Deathly Hallows," part 2 of which opens in movie theaters on Friday. (I tell my students that not for nothing does Harry play Seeker on Gryffindor’s Quidditch team, Quidditch being the wizarding world’s sport of choice.)

J.K. Rowling: 'Never say never' to more 'Potter'

Yet these are also the questions that motivated Rowling — who was struggling with her mother’s recent death — to write the series in the first place. Indeed, they’re the questions asked by all who seek a deeper understanding of our world.

In other words, the reason the Harry Potter series resonates with so many is that Harry’s journey is our journey; what he seeks, we seek.

But is what we find heretical, as some Christians have claimed?

The first winter I taught at Yale, I was a true seeker. I had moved out of my cozy attic apartment and into my parents’ home after doctors diagnosed my father with a rare neurological disease called Primary Lateral Sclerosis (PLS).

PLS is similar to Lou Gehrig’s Disease and Multiple Sclerosis, the illness from which J.K. Rowlings’ mother suffered. Like those diseases, PLS is progressive and incurable, immobilizing the muscles without affecting the mind.

Driving home from class one day, alone in my car, I found myself overwhelmed by my father’s illness, by the pained look in his eyes as he struggled to cut food with a knife, by the anxiety that plagued my mother.

And then I thought of Harry Potter.

Each week, I’d been asking my Yale students to look at Harry’s journey and to determine the significance of that journey for them. In that moment, I wondered about the significance the books held for me. Could they offer consolation, and would that consolation be antithetical to Christian faith?

In the car that day, I remembered the end of "The Deathly Hallows," when Harry, walking towards his nemesis Voldemort in the Forbidden Forest, finds himself surrounded by those who died but who loved Harry well: his mentors, Sirius and Lupin, and his parents, James and Lily.

Lily speaks first: “You’ve been so brave.”

“You’ll stay with me?” Harry asks.

“Until the very end,” responds James.

In other words, it is community and love that see us through even the greatest losses. That’s the same for Rowling and for Christians, for whom God is love. It is friendship and faith that help us walk—or drive, as I was doing at that moment—bravely to our destiny.

In that, I found consolation.

In the new Potter film – reportedly the last in the Potter franchise – we’ll see Harry as a different kind of seeker, one who struggles with his faith. His mentor, Dumbledore, is absent in a time of evil, as the wizarding world is subjected to a Hitler-like campaign to abolish anyone not of pure wizarding descent. Meanwhile, the equivalent of a tabloid journalist has published a book smearing Dumbledore’s previously unadulterated reputation.

Though Dumbledore taught Harry that the only way to defeat Voldemort is through the power of love, that force has been seriously called into question. With subjugation and violence all around and with Dumbledore’s image smeared, love doesn’t seem much worth trusting.

As Harry wanders through the wizarding world, he must seek for himself what is worth trusting and what is not. And, without giving too much away, let me say that when his faith in love finally takes root, transformative things begin to happen.

As movie theatres reel the final film, and as we reflect on the years we shared with members of Dumbledore’s Army, perhaps this is the takeaway: Seek.

Seek with all your heart and all your soul and with your closest friends by your side.

If you do, you may find yourself on an unpredictable path to places you never knew existed. You may meet people so unlike you that they could be properly called a centaur and you a house elf. You may walk into a dark and forbidden forest. You may battle your greatest enemy.

Through all of that, you may very well find love. And at the end, you may conclude, as J.K. Rowling did, that “All was well.” Kind of sounds like Christianity, doesn't it?
