From a sermon by Saint Leo the Great, pope

Christian, remember your dignity

Dearly beloved, today our Savior is born; let us rejoice. Sadness should have no place on the birthday of life. The fear of death has been swallowed up; life brings us joy with the promise of eternal happiness.

No one is shut out from this joy; all share the same reason for rejoicing. Our Lord, victor over sin and death, finding no man free from sin, came to free us all. Let the saint rejoice as he sees the palm of victory at hand. Let the sinner be glad as he receives the offer of forgiveness. Let the pagan take courage as he is summoned to life.

In the fullness of time, chosen in the unfathomable depths of God’s wisdom, the Son of God took for himself our common humanity in order to reconcile it with its creator. He came to overthrow the devil, the origin of death, in that very nature by which he had overthrown mankind.

And so at the birth of our Lord the angels sing in joy: Glory to God in the highest, and they proclaim peace to his people on earth as they see the heavenly Jerusalem being built from all the nations of the world. When the angels on high are so exultant at this marvelous work of God’s goodness, what joy should it not bring to the lowly hearts of men?

Beloved, let us give thanks to God the Father, through his Son, in the Holy Spirit, because in his great love for us he took pity on us, and when we were dead in our sins he brought us to life with Christ, so that in him we might be a new creation. Let us throw off our old nature and all its ways and, as we have come to birth in Christ, let us renounce the works of the flesh.

Christian, remember your dignity, and now that you share in God’s own nature, do not return by sin to your former base condition. Bear in mind who is your head and of whose body you are a member. Do not forget that you have been rescued from the power of darkness and brought into the light of God’s kingdom.

Through the sacrament of baptism you have become a temple of the Holy Spirit. Do not drive away so great a guest by evil conduct and become again a slave to the devil, for your liberty was bought by the blood of Christ.

The Cristeros Rule of Life

As Cristeros, we dedicate ourselves to a a life of true devotion to Jesus through Mary, particularly in the form of Our Lady of Guadalupe. Our Lady of Guadalupe, Pray for Us.

We begin our days with a Morning Offering dedicating our day:

O Jesus, through the Immaculate Heart of Mary, I offer you my prayers, works, joys and sufferings of this day, in union with the holy sacrifice of the Mass throughout the world, for the remission of my sins, for the intentions of my family and friends, and in particular for the intentions of the Holy Father. Amen.

At a high or low point during the day, we pray to the Holy Spirit, handing over our accomplishments or sufferings:

Come Holy Spirit, fill the hearts of thy faithful, and enkindle in us the fire of thy love, send forth thy spirit and we shall be created, and though shall renew the face of the earth. Amen.

At some point each day, on our own or with our family or friends, we pray to our Mother Mary in the form of Guadalupe, giving all that we have and are to Jesus through Mary by reciting one of the following:

• A daily Rosary, focusing on the Fruits of the Mystery.
• The Hail Holy Queen

Every night before we go to sleep, by ourselves or with our wife, we pray a nightly examine using the ACTS formula:

• Adoration: We adore you and Christ and we bless You, because by Your Holy Cross, You have redeemed the world.
• Contrition: Ask God for forgiveness for all the times you have sinned or fallen short that day,
• Thanksgiving: Thank God for all the gifts he has given you that day, including the grace for those moments you have acted virtuously and towards the Good.
• Supplication: We ask God for his blessings that night and the next day, either with particular requests or in general, and end with a prayer dedicating ourselves to Him through Our Lady of Guadalupe: All that we have and all that we are, we give to your hands Jesus, through the heart of Mary, your blessed mother. Amen. Our Lady of Gudalupe, Pray For us.
