Saul's Mission to Persecute the Church
1But Saul, still breathing threats and slaughter against the disciples of the Lord, went to the high priest2and asked for letters from him to the synagogues of Damascus, that if he found any who were of the Way, whether men or women, he might bring them bound to Jerusalem.
Saul does not merely threaten the Church—he inhales violence as his natural air, making his impending conversion not a gentle correction but a total demolition of everything he is.
Acts 9:1–2 introduces the last recorded act of Saul's violent campaign against the early Church: armed with official letters from the High Priest, he sets out for Damascus to hunt down followers of "the Way." These verses form the darkest point before the most dramatic conversion in Christian history, presenting Saul not merely as an opponent but as a living embodiment of hostility to the Body of Christ — and yet, implicitly, as a man already in the sightlines of divine mercy. The very intensity of his persecution sets the stage for the sovereign, irresistible character of the grace that is about to overtake him.
Verse 1 — "Still breathing threats and slaughter"
Luke's choice of the Greek word empneōn ("breathing") is visceral and deliberate. Saul does not merely speak threats; he inhales and exhales them — violence has become the very atmosphere of his existence. The imperfect continuous force of the participle suggests an ongoing, habitual state: this is not a momentary outburst but the settled disposition of a man who has organized his entire energy around the suppression of the nascent Church. Luke has already implicated Saul in the stoning of Stephen (Acts 7:58; 8:1), and chapter 8 showed him "ravaging the Church" (elymaineto, a word used of wild animals tearing flesh). Now, with the Jerusalem community already scattered, Saul extends his reach outward. His target is "the disciples of the Lord" (tous mathētas tou Kyriou) — a full titular phrase that Luke uses with theological weight: these are not a sect but the disciples of the Kyrios, the Lord, the very title applied to the Risen Christ.
That he "went to the high priest" signals institutional authority. Saul is not acting as a lone fanatic; he operates within the official machinery of the Jerusalem establishment. This detail is historically important: it reflects the reach of the Sanhedrin's jurisdictional influence over diaspora synagogues, rooted in the right to extradite Jewish offenders established under Seleucid and later Roman arrangements (cf. 1 Macc 15:21). Saul's persecution is thus not personal rage alone but the convergence of religious zeal and institutional power.
Verse 2 — "Letters to the synagogues of Damascus… those of the Way"
Damascus was a city with a substantial Jewish population and active synagogue life, situated roughly 240 km northeast of Jerusalem — a journey of several days on foot. The "letters" (epistolas) were official commissions of authority, allowing Saul to act as an agent of the Sanhedrin. That he sought authority over "men and women alike" is a detail Luke mentions deliberately, echoing what he noted in Acts 8:3: Saul had already dragged both men and women to prison. Far from trivial, this inclusivity in persecution paradoxically testifies to Luke's consistent witness that women were full and recognized members of the early Christian community — their faith warranted official suppression.
The phrase "those of the Way" (tēs hodou) is one of the oldest self-designations of the Christian movement, appearing six times in Acts and nowhere else in the New Testament. It carries rich resonance: in the Hebrew scriptures, derek (the way) evokes the path of covenant faithfulness (Ps 1; Prov 8), and in Isaiah 40:3, the "way of the Lord" is the great eschatological highway of redemption. Jesus himself had declared, "I am the Way ()" (John 14:6). To belong to "the Way" was therefore to walk in Christ, to inhabit a journey oriented entirely toward the living Lord. Saul intends to bind those on this road and drag them back — yet, within a few verses, he himself will be stopped dead on that very road by the one who the Way.
Catholic tradition reads these two verses not merely as historical prelude but as a profound theological statement about the sovereignty and priority of divine grace. The Catechism of the Catholic Church teaches that "God's free initiative demands man's free response" (CCC 2002), yet the conversion that follows in Acts 9 will press that teaching to its most dramatic expression: Saul contributes nothing to his own transformation — he is knocked from his horse, blinded, and addressed by name. The groundwork laid in verses 1–2 is essential to appreciating this: the more implacably hostile Saul appears, the more unmistakably gratuitous the grace that overcomes him will be.
St. John Chrysostom, in his Homilies on Acts, marvels at the "excess of wickedness" displayed in these verses precisely because it magnifies the mercy of God: "He who had breathed threats and slaughter is made a vessel of election — so that no one might ever despair." This is not simply consoling rhetoric; it is a doctrinal point about the nature of grace as prevenient — grace that goes before and does not wait for human merit (cf. CCC 2001).
St. Augustine, in his treatise On the Predestination of the Saints, returns repeatedly to Paul as the paradigmatic case of unconditional divine election, noting that Saul's conversion "came not from the will of the flesh, nor from the will of man, but from God" (cf. John 1:13). The Council of Orange (529 AD), later confirmed by Trent, drew on precisely this Pauline precedent to define that the beginning of faith is itself a gift of grace, not a human achievement.
Furthermore, the detail that Saul targeted "disciples of the Lord" has been read by the Fathers — preeminently in the Damascus Road encounter itself (v. 4, "Saul, why do you persecute me?") — as establishing the doctrine of the Totus Christus: the Church is the Body of Christ, so that to strike the members is to strike the Head. Pope Pius XII's encyclical Mystici Corporis Christi (1943) expounds this mystery directly, citing Paul's own later testimony as the experiential foundation of his teaching on the Body of Christ (1 Cor 12).
For contemporary Catholics, Saul in these verses is a mirror held up to the ways in which religious conviction can harden into violence — not only physical persecution, but the subtler violences of contempt, exclusion, and institutional weaponization of authority against the vulnerable. The modern Catholic who holds power in any form — in a parish, a diocese, a family, a workplace — is warned by Saul's example of how easily zeal becomes cruelty when it is severed from encounter with the living Christ.
But these verses also carry a second, more personal challenge: they invite the reader to locate themselves not only in Saul-the-persecutor but in "those of the Way" — the scattered, hunted disciples who continued to live their faith under threat. In cultures where Christianity is socially costly, ridiculed, or openly opposed, the early disciples' quiet fidelity becomes a model. They did not abandon "the Way" because powerful letters were dispatched against them.
Finally, these verses call Catholics to resist despair about anyone — including the most hostile opponents of the faith. The person most aggressively attacking the Church in your life may be the next Paul. Interceding for persecutors, as Stephen did (Acts 7:60), is not naïveté; it is cooperation with a grace already moving toward them.
The Typological Sense
The Fathers detected in Saul's condition a type of the soul enslaved by sin: "breathing threats" maps onto what St. Augustine calls the anima aversa — the soul turned away from God, directing its energies toward violence and control. Saul persecutes what he does not yet understand, just as sin always attacks the image of God in which it does not yet recognize itself. The road to Damascus becomes, in this reading, the threshold of metanoia: before grace can dawn, the night of our misdirected zeal must reach its most intense hour.
