In last week’s post, I compared repentance and the process of transformation that follows to the demolition and renovation of a house. I told you that spiritual maturity doesn’t come all at once, and that there is much work for us to do in order to experience the qualities of transformation.

So, exactly what kind of work am I talking about?

Early in the fourth century C.E., a Roman general named Constantine won a series of decisive battles against his political opponents, and for whatever reason, he felt that the God of the Christians somehow had a hand in this success. In his ascension to the throne, Constantine legalized and rapidly legitimized Christianity throughout the empire. And even if he didn’t end up professing the faith until he was on his death-bed, this was nothing short of a watershed moment not just for the Christian faith, but for religious history in general. Suddenly, it was perfectly legal to profess Jesus Christ as Lord and Savior of the world. It was completely above-board to gather regularly in order to praise “the one true God.” From that moment on, being a Christian wasn’t just harmless – it was the gold standard of Roman citizenship.

In response to this whiplash-like shift in Christianity’s relationship with culture, devoted followers of the Risen One realized that what once had been the ideal expression of faithfulness was no longer possible. Before Constantine, Christians who lived out their love for Jesus without compromise were often martyred – burned alive on stakes or pyres, tortured before gathered crowds, and, of course, crucified. And yet, as horrific an event as martyrdom was, the persecuted Church came to see it as the ultimate act of fidelity to God. Now, however, with the complete decriminalization of the Christian faith, martyrdom was off the table as a means of expressing one’s matchless devotion to God.

In response to “imperial Christianity,” many Christians who found this new, cultural faith suspect chose a new ideal expression of faithfulness. They withdrew from society and all of its creature comforts. They exiled themselves to remote deserts and harsh wilderness environments where culture could not tempt and taint them. And they began teaching a new method of spiritual practice – the way of asceticism. Granted, ascetics were nothing new, but joining fierce simplicity and the pursuit of suffering with Christian devotion had never been the norm. However, these “Desert Fathers” insisted not only on the need to remove oneself from the worldly trappings of civilization, but also to purge the carnal accumulations that affix themselves to our souls.

They spoke of something known as katharsis, the willingness to search our souls and identify the selfishness and weaknesses bedded down in the dark, hidden places within us. In order to rid ourselves of the earthly debris and spiritual rot pervading our inner beings, we must first recognize the extent of it. The standard practices of the ascetics – silence, solitude, fasting, even flagellation – puts the believer in a position for this deep “soul-searching,” and leads them to cry out for God’s divine, inside-out renovation.

As a pastor, while I don’t advocate full-blown asceticism, I do recommend believers learn about and attempt most of the ascetic practices (self-flagellation not being one of them). These ancient spiritual disciplines are incredibly powerful experiences, and accomplish much more than katharsis. However, the process of purgation is certainly one of their primary benefits.

Jesus himself seemed to support the concept of katharsis. A large portion of his famous “Sermon on the Mount” focuses on the inner catalysts for sinful behaviors. Consider the following statements from Matthew 5:

“You have heard that it was said to the people long ago, ‘You shall not murder, and anyone who murders will be subject to judgment.’ But I tell you that anyone who is angry with a brother or sister will be subject to judgment.” (21-22)

“You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.” (27-28)

“You have heard that it was said, ‘Eye for eye, and tooth for tooth.’ But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also.” (38-39)

The worst thing we can do in our interpretations of Jesus’ sermon is to chalk these statements up to hyperbole. While the Savior does indeed make use of exaggeration in his rhetoric, none of the above statements are wholly hyperbolic. Rather, they are indicative of his understanding that sin is not simply something that is done, but also something that invades us like a parasite, festers, and methodically corrupts us. It is both a contagion and a cancer.

Concurrently, the other dangerous thing modern-day Christians can do is consider personal holiness to be an unattainable ideal – a pipe dream no normal person will ever experience. As a pastor, I am deeply committed to proclaiming the gospel of God’s grace – of unconditional, divine love that knows no bounds. However, just because believers live under God’s extraordinary grace does not mean we should be okay with our sin and weakness. While not necessarily biblical, the old adage, “God loves you as you are, but he loves you too much to let you stay that way” is a truth we must accept if we ever want to enter intentionally into the process of spiritual transformation.

These days, while we may get a rush out of shaming those we disagree with, when it comes to our own, individual sense of shame, we don’t like to spend a lot of time thinking about it. If we pray about our sin, we are quick to name what we did wrong, ask for Christ’s covering of those actions, and move on. And while there is nothing incorrect about such prayers, they rarely reach the full, purgative experience they should – the kind of exercise in prayer and meditation that not only names our sins, but allows the Holy Spirit to point his searchlight into the dank recesses of a soul that has housed a capacity for such evil habits. We must not wallow in our sin, but we must not ignore its far-reaching roots either.

It is no easy thing to let the Spirit of God shine his light into the shadows of our souls. But it is an essential part of transformation. To return to the renovation metaphor, it is the moment we enter inside our decrepit houses and begin identifying all the things that must be purged, swept up, and stripped away before the work of renewal can begin. Sometimes, this cleansing is easy – shoving excess clutter into trash bags, or pulling down old screens caked with dust. Other times, however, we find cracked beams, rotting floorboards, and purposeless walls, all of which must be torn away, piece by piece, if this old house will ever be made beautiful again.

So, may you not shy away from katharsis, no matter how uncomfortable those first forays into the cobwebbed cellar of your life may be. This is dirty work – no one ever said it wouldn’t be. But you have a co-laborer with you every step of the way. He holds a bright light from which no dirt or decay can hide. He is here to show you everything this old, rundown soul can be. Trust him. He’s been doing this kind of work for thousands of years.
