I bought this t-shirt in Italy last month — featuring Andy Warhol’s artistic depiction of an erupting Mount Vesuvius.

There really isn’t anywhere you can go in and around Naples, Italy, without being in eyeshot of Mount Vesuvius. Whether you are boating off the Mediterranean coast around the islands of Ischia and Procida, landing or taking off from the international airport there, or driving one of the many autostradas intertwining a metropolis of almost four million people, the unique double-mound character of this famous mountain is never out of sight, from any direction.

Of course it is still considered one of the most, if not the most, active volcano in Europe. Since the catastrophic, violent eruption that levelled Pompeii in the first century, it has erupted about three dozen times, significantly once in the 17th century and most recently in 1944.

Geologists and volcano experts today expect another eruption from Vesuvius, and believe they will have about a 4-week warning period before the first signs lead to the eruption.

So, you can imagine the horror we felt when we saw smoke pouring from the peak of Mount Vesuvius. Just a couple days after climbing the famed Mount and learning all this history, we were driving into Naples from the north. After holding a sudden, collective breath, we exclaimed together: “It’s going to blow!”

Some of us with phones quickly called our friends. Of course I kept driving, but in Naples it seemed everyone smoked, talked on the phone and held their child in their lap while driving at 130 kms/h. You will be happy to know I kept both my hands on the wheel while my passengers did some quick research to find out that a grass fire on the south side of Mount Vesuvius was sending smoke over the top which made it look, from our point of view, like the warning signs of an immanent eruption.

Indeed we are terrified of fire when it is out of our control. I’m not talking here about the pristine and contained burn of a campfire at the end of a day of leisure play on a lake or in the backyard. People who have seen and witnessed the raging inferno of a forest fire — earlier this year in Fort McMurray, for example — can speak of the palpable terror of a consuming fire.

In the text from Hebrews for today (12:18-29), the writer describes God as a “consuming fire.” Indeed, the writer describes the religious awe from Exodus in the Old Testament as a terrifying experience: “Indeed, so terrifying was the sight that Moses said, ‘I tremble with fear.'”

What does fire mean, in the context of faith? When we experience and confront hellfire in our lives — describe it however you will, reflecting on the greatest challenges in your life now — what does the consuming fire mean? 

In the DC Comics recent film, “Suicide Squad”, our super heroes each have a special gift they use for the cause of good. One of them has the gift of fire. El Diablo is his name, and he describes his ability as the “gift of the devil.” Indeed, we make a direct association, through culture, between fire and sin, fire and evil. In Dante’s epic 14th century poem, Inferno, there are references to fire to be sure. But considering all the degrees of hell described therein, fire is not the singularly predominant symbol of hell.

In the last century, Scots preacher George MacDonald in one of his sermons poses a more nuanced reflection on the purpose of fire: “Can it be any comfort to us to be told that God loves us so that God will burn us clean?” How many of us want to be tortured? MacDonald goes on, “We do not want to be clean and we cannot bear to be tortured.” So, the natural, human tendency kicks in — better the devil we know than the devil we do not know. And we take the easy road: we remain stuck in our unhealthy life styles and viewpoints that are far from the honest truth of it all.

Part of the problem, I believe, is that for many of us, fire means punishment.

Either we want it to mean punishment, or we imagine other people do. So, we avoid the all-consuming fire of God’s presence in our lives. We don’t believe we can stand it. In the words of a famous movie line delivered in “A Few Good Men” by Jack Nicholson: “We can’t handle the truth!” And so, in our hearts at least, we run away from God.

But the bible (in Hebrews, Revelation, Exodus, and the Gospels at least) reveals that fire is not God’s punishment; fire is not meant to be torture. 

Fire is purification.

Fire is used to refine metals. The smelter melts and pours off the gold or silver, then skims off the dross until she can see her own face reflected in the molten metal — not a bad metaphor for God’s judgement. The question is, what gets purified? And the answer has to go further than merely ‘sin’. Because sin is so embedded in our lives, and will always be as long as we walk this earth. We have to go deeper. The purification of God goes to that place deep in our hearts that causes sin, that generates those unhealthy behaviours and thoughts:

Our false selves. All the excuses, the lies, the fictions, all the rationalizations, self-justifications, all the official versions and self-diagnoses we attempt to sell to others, all the self-adaptations and defensiveness to escape criticism, all the motivations that are fuelled more by selfish ambition and fear than an honest concern for the other. All these will be consumed in the fire of God’s love.

Ironically, what I often call ‘religiosity’ is also a target for God’s fire. When we are honest about our true motivations for coming to church: Is it to look good, to make a good impression, to merely reflect the group’s ideals taking on manners of speech, dress, belief, common sense, even political opinions that make us fit and feel good about ourselves? The mournful fragmentation of the Christian Church into a plethora of denominations today is an unfortunate testimony to this truth, I believe. Yet, God’s fiery love will clean us from that sort of religiousness as well.

And when all that happens, this is the joyous promise: When God’s presence breaks into our awareness, when we feel ourselves being utterly known, embraced, and accepted as we are. The embraced and accepted self is not the false self that reflects only our perfected self image; it is the real self that God created. In that moment, the false self becomes ashes. In the end, I believe that the harshest judgement of God’s consuming fire (read: mercy, love and grace) is friendlier than our own most lavish self-praise.

But do we want to go there? Do we want to change? Or, are we afraid of what we will find when we take off the masks of our false selves?

Perhaps we cannot do this. Perhaps we are too weak to confront the consuming fire on our own willpower. Perhaps our fear is too great, and we are trapped in cycles of self-delusion. Like the point of view in our sighting of smoke on Mount Vesuvius: It looked like an immanent eruption but in truth it wasn’t. Better the devil you know than the devil you don’t know. In that case, it was better the devil you knew! We choose how we want to look at things. What is our response?

I see a connection with the parable of the Wedding Banquet (Matthew 22:2-14) where you might recall the king threw out a guest who wore no wedding robe even though the guest had clearly not anticipated attending a wedding when leaving home that day. However, a little know fact: it was up to the host to supply suitable robes to invited guests in that time and culture. The truth of the matter was that this man refused the offer, likely insisting he was OK as he was. Invited, yes. Fit to be present, not yet.

The invitation to the marriage feast is given to us. The joy and freedom is promised. Perhaps the consuming fire of God is an unavoidable mercy. And the only thing we can count on, is that this mercy will be offered to us over and over again throughout our lives regardless of how we respond to the events, people and circumstances of our lives. And so, all we can do is take the next step on the pilgrimage with our God, the all-consuming fire.

For that alone, then, thanks be to God.
