God does not give heed to the ambitiousness of our prayers, because he is always ready to give to us his light, not a visible light but an intellectual and spiritual one; but we are not always ready to receive it when we turn aside and down to other things out of a desire for temporal things.
In the Catholic Church, there are many other things which most justly keep me in her bosom. The consent of peoples and nations keeps me in the Church; so does her authority, inaugurated by miracles, nourished by hope, enlarged by love, established by age. The succession of priests keeps me, beginning from the very seat of the Apostle Peter, to whom the Lord, after His resurrection, gave it in charge to feed His sheep (Jn 21:15-19), down to the present episcopate.
I beseech Thee, my God, I would fain know, if so Thou willest, for what purpose my baptism was then deferred? was it for my good that the rein was laid loose, as it were, upon me, for me to sin? or was it not laid loose? If not, why does it still echo in our ears on all sides, "Let him alone, let him do as he will, for he is not yet baptised?" but as to bodily health, no one says, "Let him be worse wounded, for he is not yet healed." How much better then, had I been at once healed; and then, by my friends' diligence and my own, my soul's recovered health had been kept safe in Thy keeping who gavest it.
