How to Identify Your Predominant Fault

Methods for identifying your predominant fault: (1) The Daily Examen — what pattern keeps appearing? (2) Ask your spouse, close friend, or director — "What is my biggest blind spot?" (3) Notice what triggers your strongest emotional reactions — anger often masks pride, anxiety often masks vanity, laziness often masks sensuality. (4) Read descriptions of the capital sins and notice which one you rationalise the most. (Ep 176, 191)

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 "how to identify your predominant fault" 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 that which is uttered by the mouth of our flesh, is the voice of the word; and is in fact called word, with reference to that from which it is taken, when it is developed externally. BASIL; This Word is not a human word. For how was there a human word in the beginning, when man received his being last of all? There was not then any word of man in the beginning, nor yet of Angels; for every.

St. Francis de Sales writes:

He shows at length, in Part I., that she alone has Mission, that she alone is sent to teach, and that thus their authority is void, and their teaching but the vain teaching of men.

St. Ignatius of Loyola writes:

In the year 1553, one Friday morning, August 4, the eve of the feast of Our Lady of the Snows, while St. Ignatius was in the garden, I began to give him an account of my soul, and, among other things, I spoke to him of how I was tempted by vain glory.

The Catechism (PD) writes:

The chief aim of the book is to be practical, and to teach Catholics what they should know, and how these truths of their Catechism are constantly coming up in the performance of their everyday duties. It is therefore neither a book of devotion.

St. Thomas Aquinas writes:

And inasmuch as he was about to teach that the Word was the Only-Begotten Son of God, that no one might think this a possible generation, he makes mention of the Word in the first place, in order to destroy the dangerous suspicion, and show that the Son was from God impassibly. And a second reason is, that He was to declare to us the things of the Father. But he does not speak of the Word simply,.

The Church's doctrinal tradition provides authoritative grounding for this teaching. Proposition T2.C.010 (de_fide) states:

The human person is composed of two essential principles: a material body and a spiritual, immortal soul. The rational soul is the substantial form of the body. Each human soul is immediately created by God.

• Scripture: ['And the Lord God formed man of the slime of the earth: and breathed into his face the breath of life, and man became a living soul.', 'Fear ye not...
• Aquinas: ['The soul is united to the body as its form. Indeed, the intellectual soul, since it can subsist of itself, is not a form whose being depends on...
• Councils: ['We define that anyone who presumes henceforth to assert, defend or hold stubbornly that the rational or intellectual soul is not the form of the...

Additionally, proposition T2.O.001 (de_fide) affirms: Adam, the first man, transgressed the commandment of God and by his sin lost the original holiness and justice in which he had been constituted. This sin of Adam is transmitted to all his descendants by propagation, not by imitation, so that it is proper to each.

For the engaged learner, understanding "how to identify your predominant fault" 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.
