The great enemies of the spiritual life are usually summarized as The Devil, The World and our Sinful Flesh. And I keep using flesh instead of the more modern sounding nature because that is the word the Apostle Paul uses. Paul’s sinful flesh is not limited to what our minds immediately jump to. The Apostle is more psychologically attuned to all the ways our gut desires to have and control things. Those things can be actual things. In more advanced forms they are people. The will to domination. In St. Augustine’s Confessions he steals the pears not because he is hungry, or because the pears were good pears, or even because they looked good. He steals the pears because he wants them. And the second he has them he discards them. And it is his meditation on his desire for the pear that defines his sinful flesh. There is nothing good that comes out of it. Any logic or self justification usually comes later to cover the venality. Augustine’s pears help to show how deep it goes in ourselves. Augustine was a wealthy man. He had better pears at home. Like Ahab desiring Naboth’s Vineyard (1 Kings 21), or the story Nathan tells to David about the rich man stealing the lone sheep of the poor man (2 Samuel 12), it is the pettiness that brings the pathos.

I’ve included a sketch out of an older catechism. It was pictorial, so these ideas were things taught to 3rd graders, maybe younger. You can see the three great enemies referenced: the devil, the flesh and the world. You can also see what that catechism put forward as the spiritual weapons against these enemies.
If the temptation was the flesh, if the desires to have and dominate are overwhelming, the spiritual weapon proposed is fasting. In Christ, through the Spirit, we can mortify the flesh (Romans 8:13). Mortify is an old King James word. The modern translation has “put to death.” It’s the same root as mortician, or probably more familiar, Morticia of the Addams family. The Spiritual logic is that either we are going to control the desires of the flesh, or the desires of the flesh are going to control us. There is no third way. As all the apostles would say, “do not be deceived (1 Corinthians 6:9 and elsewhere).” If we do not learn to control ourselves, a fruit of the Spirit is self-control (Galatians 5:23), what hope do we have of larger things such as the world or the devil?
We have a few weeks in lent, so I’ll return in future weeks with some comments about the other two. Fasting, prayer and almsgiving are the traditional penitential acts of Lent. Each one deserves 500 words alone. But one last word now. Please notice that none of these practices are practices of the law. We do not do these things to deserve salvation. In Christ the victory has been given to us. And if we find ourselves lost in the flesh, the world or to Satan, Christ calls us back. Every sinner who repents is greeted as the Father did the prodigal son. These practices are Spiritual practices. They are done in the power of the Holy Spirit. And those who are mature in the faith do not leave such things up to chance, but instead, having crucified the flesh, keep in step with the Spirit (Galatians 5:25). Lent is a season to hear what rhythm your step is keeping.
