← Latinum Institute Ecclesiastical Latin Reading Course
Pectus, pectoris is a third-declension neuter noun meaning “chest” or “breast” in its literal, anatomical sense. However, in Ecclesiastical Latin—the living language of the Church’s Scripture, liturgy, and theology—pectus transcends mere anatomy to become a profound spiritual term denoting the interior life: the heart as the seat of emotions, the mind as the seat of understanding, and the soul as the dwelling place of God.
This word appears at frequency rank 183 in the Dickinson Core Vocabulary, reflecting its fundamental importance in Latin literature. For the Christian reader, pectus carries especial weight in three domains: -
The Vulgate Bible: From the serpent cursed to crawl “upon its breast” (super pectus tuum, Genesis 3:14) to the penitent publican “striking his breast” (percutiēbat pectus suum, Luke 18:13) to St. John reclining “upon Jesus’s breast” (supra pectus Jēsū, John 13:25). -
The Sacred Liturgy: In the Confiteor, the faithful strike their breasts (percutit sibi pectus) at the words “mea culpa, mea culpa, mea maxima culpa”—an embodied prayer connecting to the publican’s humble repentance. -
Patristic Theology: The Church Fathers used pectus to speak of the interior Christian life, where faith dwells, where the Holy Spirit moves, and where conversion happens.

FAQ Schema: What does pectus mean in Ecclesiastical Latin? The word pectus primarily means “chest” or “breast” (the front part of the torso), but in Church Latin it is used metaphorically to mean “heart” (seat of faith and love), “mind” (seat of understanding), or “soul” (the interior person where God speaks).
In this lesson’s 30 examples, you will encounter pectus in its physical sense, its penitential-liturgical sense (striking the breast in contrition), and its spiritual-theological sense (the interior heart where grace operates). The declension follows the third-declension neuter pattern with stem pector-.

✾ ❦ ✾ ❦ ✾ ✾ ❦ ✾ ❦ ✾ ✾ ❦ ✾ ❦ ✾
The word pectus holds unique importance in Catholic liturgical practice through the gesture of striking the breast (percutere pectus or percutere sibi pectus). This gesture accompanies the Confiteor during the Penitential Act of Mass:
“Confiteor Deō omnipotentī... quia peccāvī nimis cogitātiōne, verbō et opere: (percutiēns sibi pectus) meā culpā, meā culpā, meā maximā culpā...”
The rubric (percutiēns sibi pectus) instructs the faithful to strike their breast. This gesture originates in the Gospel parable of the Pharisee and the Publican (Luke 18:9-14), where the humble tax collector “would not even lift his eyes to heaven, but kept striking his breast (percutiēbat pectus suum), saying: ‘God, be merciful to me, a sinner.’”
Theological Meaning of the Gesture: Romano Guardini wrote: “To brush one’s clothes with the tips of one’s fingers is not to strike the breast. We should beat upon our breasts with our closed fists... It is an honest blow, not an elegant gesture. To strike the breast is to beat against the gates of our inner world in order to shatter them.”
Pope Benedict XVI (then-Cardinal Ratzinger) observed: “When we say meā culpā, we turn, so to speak, to ourselves, to our own front door.”
Genesis 3:14 — In cursing the serpent, God commands: “super pectus tuum gradiēris” (”upon your belly you shall crawl”). Here pectus means the physical belly/breast on which the snake crawls—a mark of degradation.
John 13:25 — At the Last Supper, the Beloved Disciple “recubuit supra pectus Jēsū” (”reclined upon Jesus’s breast”). This intimate position symbolizes mystical union and hearing the heartbeat of Christ. Medieval devotion to the Sacred Heart drew upon this image.
Daniel 2:32 — In Nebuchadnezzar’s dream, the statue’s “pectus et bracchia dē argentō” (”breast and arms of silver”) represented the kingdoms succeeding Babylon.
St. Augustine testified that when his congregation heard words like “mercy” or “confess,” they would strike their breasts so forcefully that the sound rumbled through the church—a sign of vigorous embodied faith.
The phrase “pectus pūrum” (”pure heart/breast”) appears in moral exhortation, echoing the Beatitude “Blessed are the pure in heart.”

propitius estō: future imperative—a solemn, formal petition -
mihi peccātōrī: double dative construction—”to me, a sinner”
F-E: THEOLOGICAL COMMENTARY
This verse provides the Scriptural foundation for the liturgical gesture of striking the breast. Christ tells this parable to contrast the self-righteous Pharisee (who thanks God he is not like sinners) with the humble tax collector who stands at a distance, unable even to lift his eyes, and strikes his breast in confession.
Christ’s conclusion: “This man went down to his house justified rather than the other” (Luke 18:14). The Church has preserved the publican’s gesture in the Mass as a perpetual reminder that all approach God as sinners in need of mercy, and that humility—embodied in the striking of the breast where sin originates—is the posture that receives grace.
The imperfect tense percutiēbat indicates repeated striking, suggesting sustained and earnest contrition rather than a single perfunctory gesture.
