St. Louis, King of France, patron of Tertiaries, was the ninth of his name. He was born at Poissy, France, in 1214. His father was Louis VIII, and his mother was Blanche, daughter of Alfonso VIII of Castille, surnamed the Conqueror. At the age of twelve he lost his father, and his mother became regent of the kingdom. From his tenderest infancy she had inspired him with a love for holy things.
In 1234, he married Margaret, the virtuous daughter of Raymond Berenger, Count of Provence, and two years later he took the reigns of government into his own hands. Louis loved sermons, heard two Masses daily, and was surrounded, even while traveling, with priests chanting the hours. Though he was happy in the company of priests and other men of wisdom and experience, he did not hesitate to oppose churchmen when they proved unworthy. The usual tourneys and festivities at the creation of new knights were magnificently celebrated, but Louis forbade at his court any diversion dangerous to morals.
In 1238, he headed a crusade, in which he fell a prisoner among the Mohammedans, but a truce was concluded and he was set free and he returned to France. In 1267, he again set out for the East at the head of a crusade but he never again beheld his native land. In 1270, he was stricken by the pestilence at the siege of Tunis, and after receiving the Last Sacraments, he died.
Excerpts from a translation of a letter that the holy king wrote to his son, Phillip:
Dear son, since I desire with all my heart that you be well “instructed in all things, it is in my thought to give you some advice this writing. For I have heard you say, several times, that you remember my words better than those of any one else.?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.
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.
If our Lord send you any adversity, whether illness or other in good patience, and thank Him for it, thing, you should receive it in good patience and be thankful for it, for you ought to believe that He will cause everthing to turn out for your good; and likewise you should think that you have well merited it, and more also, should He will it, because you have loved Him but little, and served Him but little, and have done many things contrary to His will.
If our Lord send you any prosperity, either health of body or other thing you ought to thank Him humbly for it, and you ought to be careful that you are not the worse for it, either through pride or anything else, for it is a very great sin to fight against our Lord with His gifts.
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.
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.
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.? Maintain the good customs of your realm, and put down the bad ones. Do not oppress your people and do not burden them with tolls or tailles, except under very great necessity.
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.?Love all good, and hate all evil, in whomsoever it may be.?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.
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.
Finally, most sweet son, I conjure and require you that, if it please our Lord that I should die before you, you have my soul succored with masses and orisons, and that you send through the congregations of the kingdom of France, and demand their prayers for my soul, and that you grant me a special and full part in all the good deeds which you perform.
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.

Let Us Pray
O Lord, King of kings, Jesus Christ,

Who livest and reignest,
world without end.
