...3. Therefore, dear son, the first thing I advise is that you fix your whole heart upon God, and love Him with all your strength, for without this no one can be saved or be of any worth.
4. You should, with all your strength, shun everything which you believe to be displeasing to Him. And you ought especially to be resolved not to commit mortal sin, no matter what may happen and should permit all your limbs to be hewn off, and suffer every manner of torment, rather than fall knowingly into mortal sin.
...7. Dear son, I advise you that you accustom yourself to frequent confession, and that you choose always, as your confessors, men who are upright and sufficiently learned, and who can teach you what you should do and what you should avoid. You should so carry yourself that your confessors and other friends may dare confidently to reprove you and show you your faults.
8. Dear son, I advise you that you listen willingly and devoutly the services of Holy Church, and, when you are in church, avoid to frivolity and trifling, and do not look here and there; but pray to God with lips and heart alike, while entertaining sweet thoughts about Him, and especially at the mass, when the Body and Blood of our Lord Jesus Christ are consecrated, and for a little time before.
9. Dear son, have a tender pitiful heart for the poor, and for all those whom you believe to be in misery of heart or body, and, according to your ability, comfort and aid them with some alms.
...13. Dear son, see to it that all your associates are upright, whether clerics or laymen, and have frequent good converse with them; and flee the society of the bad. And listen willingly to the word of God, both in open and in secret; and purchase freely prayers and pardons.
14. Love all good, and hate all evil, in whomsoever it may be.
15. Let no one be so bold as to say, in your presence, words which attract and lead to sin, and do not permit words of detraction to be spoken of another behind his back.
!6. Suffer it not that any ill be spoken of God or His saints in your presence, without taking prompt vengeance. But if the offender be a clerk or so great a person that you ought not to try him, report the matter to him who is entitled to judge it.
...23. Moreover, I advise you to love dearly the clergy, and, so far as you are able, do good to them in their necessities, and likewise love those by whom God is most honored and served, and by whom the Faith is preached and exalted.
...25. Love your brothers, and always wish their well-being and their good advancement, and also be to them in the place of a father, to instruct them in all good. But be watchful lest, for the love which you bear to one, you turn aside from right doing, and do to the others that which is not meet.
...31. Dear son, I advise you always to be devoted to the Church of Rome, and to the sovereign pontiff, our father, and to bear him the the reverence and honor which you owe to your spiritual father.
...36. In conclusion, dear son, I give you all the blessings which a good and tender father can give to a son, and I pray our Lord Jesus Christ, by His mercy, by the prayers and merits of His blessed Mother, the Virgin Mary, and of angels and archangels and of all the saints, to guard and protect you from doing anything contrary to His will, and to give you grace to do it always, so that He may be honored and served by you. And this may He do to me as to you, by His great bounty, so that after this mortal life we may be able to be together with Him in the eternal life, and see Him, love Him, and praise Him without end. Amen. And glory, honor, and praise be to Him who is one God with the Father and the Holy Spirit; without beginning and without end. Amen.
