From a letter by Saint Athanasius, bishop
The Word took our nature from Mary

The Apostle tells us: The Word took to himself the sons of Abraham, and so had to be like his brothers in all things. He had then to take a body like ours. This explains the fact of Mary’s presence: she is to provide him with a body of his own, to be offered for our sake. Scripture records her giving birth, and says: She wrapped him in swaddling clothes. Her breasts, which fed him, were called blessed. Sacrifice was offered because the child was her firstborn. Gabriel used careful and prudent language when he announced his birth. He did not speak of “what will be born in you” to avoid the impression that a body would be introduced into her womb from outside; he spoke of “what will be born from you” so that we might know by faith that her child originated within her and from her.

By taking our nature and offering it in sacrifice, the Word was to destroy it completely and then invest it with his own nature, and so prompt the Apostle to say: This corruptible body must put on incorruption; this mortal body must put on immortality. This was not done in outward show only, as some have imagined. This is not so. Our Savior truly became man, and from this has followed the salvation of man as a whole. Our salvation is in no way fictitious, nor does it apply only to the body. The salvation of the whole man, that is, of soul and body, has really been achieved in the Word himself.

What was born of Mary was therefore human by nature, in accordance with the inspired Scriptures, and the body of the Lord was a true body: It was a true body because it was the same as ours. Mary, you see, is our sister, for we are all born from Adam.

The words of Saint John: the Word was made flesh, bear the same meaning, as we may see from a similar turn of phrase in Saint Paul: Christ was made a curse for our sake. Man’s body has acquired something great through its communion and union with the Word. From being mortal it has been made immortal; though it was a living body it has become a spiritual one; though it was made from the earth it has passed through the gates of heaven.

Even when the Word takes a body from Mary, the Trinity remains a Trinity, with neither increase nor decrease. It is for ever perfect. In the Trinity we acknowledge one Godhead, and thus one God, the Father of the Word, is proclaimed in the Church.

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 Guadalupe, Pray For us.
