What Is Mortification?

Mortification comes from the Latin "mors" (death) — putting to death the disordered parts of yourself so that Christ can live in you more fully. It is NOT self-punishment, masochism, or earning God's love. It IS making room for God by removing obstacles. Interior mortification (pride, ego, disordered thoughts) is MORE important than exterior (fasting, physical discomfort). (Ep 642, 643)

To appreciate the full significance of this teaching, it helps to situate it within the broader framework of the Catholic spiritual tradition. The great masters of the interior life — Teresa of Avila, John of the Cross, Francis de Sales, and Ignatius of Loyola — each brought their distinctive charism and experience to bear on questions like this one. Their convergent testimony, spanning centuries and diverse vocations, gives this teaching a depth and authority that goes far beyond any single author's perspective.

Understanding "what is mortification?" requires attending to both its doctrinal foundations and its practical implications. The Catholic tradition insists that authentic spiritual knowledge is never merely theoretical — it must be tested in prayer, refined through experience, and ultimately verified by its fruits in the life of the soul. This is why the Church's greatest teachers on the spiritual life are not only theologians but saints — men and women who lived what they taught, and whose writings carry the authority of verified experience.

At the same time, the tradition is careful to anchor experiential testimony in sound doctrine. The Doctors of the Church do not simply report their own experiences; they interpret those experiences in light of Scripture, the Fathers, and the Church's magisterial teaching. This integration of experience and doctrine is one of the defining characteristics of Catholic spiritual theology, and it is what gives the tradition its remarkable combination of depth and reliability.

The richness of the tradition becomes apparent when we listen to the voices of the masters themselves. Each brings a distinctive perspective to this teaching, yet all converge on its essential truth.

St. Thomas Aquinas writes:

For as in the beginning though the element of earth was the subject-matter, the man was the work of the fashioner; so now too, though the element of water is the subject-matter, the whole work is done by the Spirit of grace. He then gave Paradise for a place to dwell in; now He has opened heaven to us. But what need is there of water, to those who receive the Holy Ghost?

St. Teresa of Avila writes:

If they find it proceeds from weakness, then they must forbid fasting and mortification—that is, when not of obligation ; and the time may come when with a safe conscience they may forbid them altogether, and assign them duties in the.

St. Ignatius of Loyola writes:

To do something great for the glory of his God, to emulate saintly men in all that they had done before him--this was the only object of Ignatius in his practices of external mortification.

The Church Fathers writes:

Better the precipice than the pitfall; better the tortures of curable disease than the painlessness of mortification; and so, whatever your soul’s guilt and danger, better to be aware of it.

St. Thomas Aquinas writes:

But these things were done in the month of September, the twenty-second day of the month, upon which the Jews were bound to observe the feast of the Tabernacles, just before the equinox, at which the night began to be longer than the day, because Christ must increase, but John must decrease And those days of fasting were not without their meaning; for by the mouth of John, repentance and.

The Church's doctrinal tradition provides authoritative grounding for this teaching. Proposition T4.G.007 (de_fide) states:

God gives sufficient grace to all the just for the observance of the divine commandments. God does not command the impossible, but by commanding admonishes us to do what we can and to pray for what we cannot.

• Scripture: ['God is faithful, who will not suffer you to be tempted above that which you are able: but will make also with temptation issue, that you may be...

• Councils: ['God does not command impossibilities, but by commanding admonishes thee to do what thou canst, and to pray for what thou canst not, and aids thee...

Additionally, proposition T4.G.009 (de_fide) affirms: The justified person can truly merit an increase of sanctifying grace, eternal life, and an increase of heavenly glory by good works performed in the state of grace and under the influence of actual grace.

For the engaged learner, understanding "what is mortification?" opens a path to deeper prayer and more fruitful cooperation with grace. The sources cited above show that this is not abstract theology but a lived reality that has shaped the spiritual lives of countless saints and ordinary Christians across two millennia.

The practical challenge is to take this teaching into one's own prayer and daily life. This might begin with reflective reading of one or more of the sources quoted above, followed by prayerful consideration of how this teaching applies to one's current spiritual situation. The tradition consistently emphasises that spiritual growth comes not from accumulating information but from allowing truth to penetrate the heart through prayer, sacramental life, and faithful practice.

As St. Francis de Sales reminds us, the devout life is possible in every state — what matters is not extraordinary circumstances but extraordinary love applied to ordinary duties. This teaching invites precisely that kind of response: a deepening of one's relationship with God through understanding and practice, sustained by the rich resources of the tradition.
