What is concupiscence?

Concupiscence is not a word most people use in ordinary conversation, but the reality it names is painfully familiar to anyone who has ever wanted something they knew they should not want. The term, drawn from Latin, refers to disordered desire, cravings within us that are bent toward self rather than toward God, surfacing as covetousness, lust, envy, or an appetite for more than God has given. It is not simply having desires; desire itself is part of being human and is not automatically sinful. Concupiscence names the specific twisting of desire that pulls a person toward what God forbids.

James traces the anatomy of temptation directly to this inward pull: 'each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death' (James 1:14-15). Paul gives a strikingly personal account of the same struggle in Romans 7, describing the commandment against coveting as the very thing that exposed the desire already lodged within him: 'if it had not been for the law, I would not have known sin. For I would not have known what it is to covet if the law had not said, You shall not covet... sin, seizing an opportunity through the commandment, produced in me all kinds of covetousness' (Romans 7:7-8). The Tenth Commandment itself targets this inward reality rather than only outward acts, forbidding coveting a neighbor's house, spouse, or possessions (Exodus 20:17), showing that God's law has always addressed desire, not merely behavior.

Christian traditions have long debated a subtle but significant question: is concupiscence itself sin, or merely the occasion and raw material for sin once a person consents to it? The Reformed and Lutheran traditions, following Paul's language in Romans 7 about 'sin that dwells within me' (Romans 7:17, 20), have generally held that disordered desire is itself sinful, a remaining corruption believers must continually mortify, even before it produces an outward act. The Roman Catholic tradition, following its own historic teaching, has generally distinguished concupiscence as an inclination or wound left by original sin, not sin properly speaking unless a person freely consents to it. Both traditions agree, however, that this pull toward disordered desire is real, dangerous, and present even in genuine believers, and that it must be actively resisted rather than indulged or ignored.

It can be discouraging to notice how often unwanted desires arise unbidden, even in a heart that genuinely wants to honor God. But the presence of concupiscence is not itself proof of a fake or failing faith; it is the ordinary experience of every believer still living in a body not yet fully redeemed. Paul's anguished cry, 'Wretched man that I am! Who will deliver me from this body of death?' (Romans 7:24), is followed immediately by hope, not despair: 'Thanks be to God through Jesus Christ our Lord!' (Romans 7:25). The presence of the struggle is evidence of a conscience alive to God, not evidence of abandonment by him.

It is worth noticing that Paul writes this passage in the present tense, describing an experience contemporaneous with his letter, not a struggle safely left behind in his pre-conversion past. Whatever one concludes about the precise autobiographical details, the passage functions in Scripture as a realistic picture of ongoing Christian experience, offered so that believers battling their own disordered desires would not conclude, wrongly, that the presence of the battle itself disqualifies them from genuine faith. The apostle who wrote most of the New Testament's letters on grace also wrote the most searingly honest description of concupiscence's ongoing pull, and he did not consider the two in any tension.

Scripture does not leave believers to manage concupiscence through sheer willpower. Paul instructs believers to 'put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness' (Colossians 3:5), language that assumes real, ongoing effort empowered by the Spirit rather than passive resignation. The remedy is not simply suppressing desire but redirecting it, filling the heart with delight in God so thoroughly that lesser cravings lose their grip. 'Delight yourself in the Lord, and he will give you the desires of your heart' (Psalm 37:4) points toward this reordering, a heart increasingly satisfied in God rather than starving for substitutes. This lifelong process, the Spirit progressively conforming disordered desire to God's own good desires, is part of what it means to be sanctified.

Suppression alone, gritting your teeth and refusing to think about a craving, tends to backfire, giving the desire even more attention by the sheer effort of trying not to notice it. The biblical strategy is closer to replacement than suppression, filling the imagination and affections with something more compelling than the disordered desire, so that the craving is not merely denied but genuinely outcompeted. This is one reason regular engagement with Scripture, prayer, worship, and Christian community matters so much practically, not as religious box-checking, but as the ordinary means by which a heart's deepest cravings are gradually retrained toward their proper object.
