And so he began attacking the Christians who remained in Jerusalem. He broke into houses and violently seized Christians hidden there, so that he might shut them up in prisons.
This was like the attack of a wild beast. Therefore the writer says that Saul ravaged the Church.
For individual members of the Church, these torments were undoubtedly very painful. Yet the Church in her fullness, with Christ as her Head, was certainly not placed in extreme danger by them.
For, according to Christ’s promise, even the gates of Hades cannot prevail against her (cf. Mt 16:18).
The visible sign that Saul’s ravaging of the Church was powerless, or weak in power, was this. As she diminished in Jerusalem, she grew elsewhere in still greater measure through the preaching of the scattered Christians.
Thus one may even say that Saul’s persecution of the Church was only a negative means of strengthening her. Later, his apostolic preaching became a positive means for her spread.
“Having permitted the enemies to act against her by persecutions, Providence directs the course of events so that persecution only binds the union of believers more firmly.
It gives them greater courage and, through the scattering of persecuted confessors of the holy faith in Judea, lays the foundation of the Church in lands of other beliefs.
Until this time the teaching of Jesus Christ, one might say, was enclosed within the walls of Jerusalem. Now the very finger of God points to a new field.”
Blessed Theophylact calls Saul’s rage “a great frenzy, which he committed because he had given his soul for the law.”
