Prayer is the wing wherewith the soul flies to heaven, and meditation the eye wherewith we see God.
And let them remember that prayer should accompany the reading of Sacred Scripture, so that God and man may talk together; for "we speak to Him when we pray; we hear Him when we read the divine saying."
Stephen prayed for his persecutors, who had not been able even to listen to the Name of Christ, when he said of those very men by whom he was being stoned: "Lord, lay not this sin to their charge" And we see the result of this prayer in the case of the Apostle, for Paul, who kept the garments of those who were stoning Stephen, not long after became an apostle by the grace of God, having before been a persecutor.
But if these beings guard you, they do so because they have been summoned by your prayers.
