3 Therefore I follow, with halting pace indeed as yet, the great examples of the just, if I may through your prayers apprehend that for which I have been apprehended by the compassion of God. Guide, therefore, this infant creeping on the ground, and by your steps teach him to walk. For I would not have you judge of me by the age which began with my natural birth, but by that which began with my spiritual new birth. For as to the natural life, my age is that which the cripple, healed by the apostles by the power of their word at the gate Beautiful, had attained. But with respect to the birth of my soul, mine is as yet the age of those infants who, being sacrificed by the death-blows which were aimed at Christ, preceded with blood worthy of such honour the offering of the Lamb, and were the harbingers of the passion of the Lord. Therefore, as I am but a babe in the word of God, and as to spiritual age a sucking child, satisfy my vehement desire by nourishing me with your words, the breasts of faith, and wisdom, and love.
If you consider only the office which we both hold, you are my brother; but if you consider the ripeness of your understanding and other powers, you are, though my junior in years, a father to me; because the possession of a venerable wisdom has promoted you, though young, to a maturity of worth, and to the honour which belongs to those who are old. Foster and strengthen me, then, for I am, as I have said, but a child in the sacred Scriptures and in spiritual studies; and seeing that, after long contendings and frequent shipwreck, I have but little skill, and am even now with difficulty rising above the waves of this world, do you, who have already found firm footing on the shore, receive me into the safe refuge of your bosom, that, if it please you, we may together sail towards the harbour of salvation.
Meanwhile, in my efforts to escape from the dangers of this life and the abyss of sin, support me by your prayers, as by a plank, that from this world I may escape as one does from a shipwreck, leaving all behind.
