Saint Damasus was born in Rome at the beginning of the fourth century. His father, a widower, had received Holy Orders there and served as parish priest in the church of St. Laurence. Damasus was archdeacon of the Roman Church in 355 when the Pope, Saint Liberius, was banished to Berda. Damases followed him into exile, but afterwards returned to Rome. On the death of Saint Liberius in 366, our Saint was chosen to succeed him, at the age of sixty-two. A certain Ursinus, jealous of his election and desiring for himself that high office, had himself proclaimed pope by his followers, inciting a revolt against Damasus in Rome, in which 137 people died. The holy Pope did not choose to resort to armed defense, but the Emperor Valentinian, to defend him, drove the usurper from Rome for a time. Later he returned, and finding accomplices for his evil intentions, accused the holy Pontiff of adultery. Saint Damasus took only such action as was becoming to the common father of the faithful. He assembled a synod of forty-four bishops, in which he justified himself so well that the calumniators were excommunicated and banished. Having freed the Church of this new schism, Saint Damasus turned his attention to the extirpation of Arianism in the West and of Apollinarianism in the East, and for this purpose convened several councils. He sent Saint Zenobius, later bishop of Florence, to Constantinople in 381 to console the faithful, cruelly persecuted by the Emperor Valens. He commanded Saint Jerome to prepare a correct Latin version of the Bible, since known as the Vulgate, and he ordered the Psalms to be sung accordingly. He rebuilt and adorned the Church of Saint Laurence, still called Saint Laurence in Damaso. He caused all the springs of the Vatican to be drained, which were inundating the tombs of the holy persons buried there, and he decorated the sepulchers of a great number of martyrs in the cemeteries, adorning them with epitaphs in verse. Saint Damasus is praised by Theodoret as head of the famous doctors of divine grace of the Latin church. The General Council of Chalcedon calls him the "honor and glory of Rome." Having reigned for eighteen years and two months, he died on December 10, 384, when he was nearly eighty years old. In the eighth century, his relics were definitively placed in the church of Saint Laurence in Damaso, except for his head, which was conserved in the Basilica of Saint Peter. He presided over the Council of Rome of 382 that determined the canon or official list of Sacred Scripture. Throughout his papacy, St. Damasus spoke out against major heresies in the church and encouraged production of the Vulgate Bible with his support for St. Jerome. He helped reconcile the relations between the Church of Rome and the Church of Antioch, and encouraged the veneration of martyrs.

St. Eulalia descended from one of the most prominent families in Spain in 290 AD. She was educated in the Christian religion and was taught the sentiments of perfect piety. From her infancy she distinguished herself by an admirable sweetness of temper, modesty and devotion. She showed a great love of the holy state of virginity, and by her seriousness and her contempt of dress, ornaments diversions and worldly company, she gave early signs of her sincere desire to lead a heavenly life on earth. Her heart was raised above the world before she was thought capable of knowing it, so that its amusements, which usually fill the minds of youth, had no charms for her, and every day of her life she continued to grow in virtue.Legends say that she was just twelve years old when the bloody edicts of the Emporer Diocletian were issued in 304, by which it was ordered that all persons, without exception of age, sex, or profession, should be compelled to offer sacrifice to the gods of the empire.Eulalia, although young, took the publication of this order as a sign of battle, but her mother, observing her impatient ardor for martyrdom, carried her into the country. However, the young saint quickly found a means to make her escape by night, and after much fatigue, arrived at Merida before daybreak.That same morning, as soon as the court convened, she presented herself before the cruel judge, whose name was Dacian, and reproached him with impiety in attempting to destroy souls by compelling them to renounce the only true God.The governor then commanded her to be seized. First, employing caresses, Dacian presented to her the advantages which her birth, youth and fortune gave her in the world, and the grief which her disobedience would bring to her parents. Seeing that these temptations had no effect, he began to threaten her, placing the most cruel instruments of torture before her eyes, saying to her, "All this you shall escape if you will but touch a little salt and frankincense with the tip of your finger." Provoked at these seducing flatteries, she threw down the idol, trampled upon the cake which was laid for the sacrifice and spat at the judge -- an action only to be excused by her youth and inattention under the influence of a warm zeal, and fear of the snares which were laid before her. Upon the judge's order, two executioners began to tear her tender sides with iron hooks, so as to leave the very bones bare. While this was happening, she called the strokes the trophies of Christ. Next, lighted torches were applied to her breasts and sides: under which torment, instead of groans, nothing was heard from her mouth but thanksgivings. The fire at length catching her hair, surrounded her head and face, and the saint was stifled by the smoke and flame.History says that a white dove seemed to come out of her mouth, and to wing its way upward when the holy martyr expired: at which prodigy the executioners were so much terrified that they fled and left the body. Her relics are kept with great veneration at Oviedo, where she is honored as patroness. The Roman Martyrology mentions her name on December 10.

On Dec. 9, Roman Catholics celebrate St. Juan Diego, the indigenous Mexican Catholic convert whose encounter with the Virgin Mary began the Church's devotion to Our Lady of Guadalupe.In 1474, 50 years before receiving the name Juan Diego at his baptism, a boy named Cuauhtlatoatzin -- “singing eagle� -- was born in the Anahuac Valley of present-day Mexico. Though raised according to the Aztec pagan religion and culture, he showed an unusual and mystical sense of life even before hearing the Gospel from Franciscan missionaries.In 1524, Cuauhtlatoatzin and his wife converted and entered the Catholic Church. The farmer now known as Juan Diego was committed to his faith, often walking long distances to receive religious instruction. In December of 1531, he would be the recipient of a world-changing miracle.On Dec. 9, Juan Diego was hurrying to Mass to celebrate the Feast of the Immaculate Conception. But the woman he was heading to church to celebrate came to him instead.In the native Aztec dialect, the radiant woman announced herself as the “ever-perfect holy Mary, who has the honor to be the mother of the true God.�“I am your compassionate Mother, yours and that of all the people that live together in this land,� she continued, “and also of all the other various lineages of men.�She asked Juan Diego to make a request of the local bishop. “I want very much that they build my sacred little house here� -- a house dedicated to her son Jesus Christ, on the site of a former pagan temple, that would “show him� to all Mexicans and “exalt him� throughout the world.She was asking a great deal of a native farmer. Not surprisingly, his bold request met with skepticism from Bishop Juan de Zumárraga. But Juan Diego said he would produce proof of the apparition, after he finished tending to his uncle whose death seemed imminent.Making his way to church on Dec. 12, to summon a priest for his uncle, Juan Diego again encountered the Blessed Virgin. She promised to cure his uncle and give him a sign to display for the bishop. On the hill where they had first met he would find roses and other flowers, though it was winter.Doing as she asked, he found the flowers and brought them back to her. The Virgin Mary then placed the flowers inside his tilma, the traditional cloak-like garment he had been wearing. She told him not to unwrap the tilma containing the flowers until he had reached the bishop.When he did, Bishop Zumárraga had his own encounter with Our Lady of Guadalupe – through the image of her that he found miraculously imprinted on the flower-filled tilma. The Mexico City basilica that now houses the tilma has become, by some estimates, the world's most-visited Catholic shrine.The miracle that brought the Gospel to millions of Mexicans also served to deepen Juan Diego's own spiritual life. For many years after the experience, he lived a solitary life of prayer and work in a hermitage near the church where the image was first displayed. Pilgrims had already begun flocking to the site by the time he died on Dec. 9, 1548, the 17th anniversary of the first apparition.Blessed John Paul II beatified St. Juan Diego in 1990, and canonized him in 2002.

"The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Savior of the human race, preserved immune from all stain of original sin." In 1854, Pope Pius IX's solemn declaration, "Ineffabilis Deus," clarified with finality the long-held belief of the Church that Mary was conceived free from original sin. Mary was granted this extraordinary privilege because of Her unique role in history as the Mother of God. That is, she received the gift of salvation in Christ from the very moment of her conception. Even though Mary is unique in all humanity for being born without sin, she is held up by the Church as a model for all humanity in Her holiness and Her purity in her willingness to accept the Plan of God for her. Every person is called to recognize and respond to God’s call to their own vocation in order to carry out God’s plan for their life and fulfill the mission prepared for them since before the beginning of time. Mary’s “Let it be done to me according to Thy Word,� in response of the Angel Gabriel’s greeting, is the response required of all Christians to God’s Plan. The Solemnity of the Immaculate Conception is a time to celebrate the great joy of God’s gift to humanity in Mary, and to recognize with greater clarity, the truth that each and every human being has been created by God to fulfill a particular mission that he and only he can fulfill. “The word of the Lord came to me thus: "Before I formed you in the womb I knew you, before you were born I dedicated you, a prophet to the nations I appointed you." (Jeremiah 1:5-6)

Today the Catholic Church celebrates the memory of St. Ambrose, the brilliant Bishop of Milan who influenced St. Augustine's conversion and was named a Doctor of the Church. Like Augustine himself, the older Ambrose, born around 340, was a highly educated man who sought to harmonize Greek and Roman intellectual culture with the Catholic faith. Trained in literature, law, and rhetoric, he eventually became the governor of Liguria and Emilia, with headquarters at Milan. He manifested his intellectual gifts in defense of Christian doctrine even before his baptism. While Ambrose was serving as governor, a bishop named Auxentius was leading the diocese. Although he was an excellent public speaker with a forceful personality, Auxentius also followed the heresy of Arius, which denied the divinity of Christ. Although the Council of Nicaea had reasserted the traditional teaching on Jesus' deity, many educated members of the Church – including, at one time, a majority of the world's bishops – looked to Arianism as a more sophisticated and cosmopolitan version of Christianity. Bishop Auxentius became notorious for forcing clergy throughout the region to accept Arian creeds. At the time of Auxentius' death, Ambrose had not yet even been baptized. But his deep understanding and love of the traditional faith were already clear to the faithful of Milan. They considered him the most logical choice to succeed Auxentius, even though he was still just a catechumen. With the help of Emperor Valentinan II, who ruled the Western Roman Empire at the time, a mob of Milanese Catholics virtually forced Ambrose to become their bishop against his own will. Eight days after his baptism, Ambrose received episcopal consecration on Dec. 7, 374. The date would eventually become his liturgical feast. Bishop Ambrose did not disappoint those who had clamored for his appointment and consecration. He began his ministry by giving everything he owned to the poor and to the Church. He looked to the writings of Greek theologians like St. Basil for help in explaining the Church's traditional teachings to the people during times of doctrinal confusion. Like the fathers of the Eastern Church, Ambrose drew from the intellectual reserves of pre-Christian philosophy and literature to make the faith more comprehensible to his hearers. This harmony of faith with other sources of knowledge served to attract, among others, the young professor Aurelius Augustinus – a man Ambrose taught and baptized, whom history knows as St. Augustine of Hippo. Ambrose himself lived simply, wrote prolifically, and celebrated Mass each day. He found time to counsel an amazing range of public officials, pagan inquirers, confused Catholics and penitent sinners. His popularity, in fact, served to keep at bay those who would have preferred to force him from the diocese, including the Western Empress Justina and a group of her advisers, who sought to rid the West of adherence to the Nicene Creed, pushing instead for strict Arianism. Ambrose heroically refused her attempts to impose heretical bishops in Italy, along with her efforts to seize churches in the name of Arianism. Ambrose also displayed remarkable courage when he publicly denied communion to the Emperor Theodosius, who had ordered the massacre of 7,000 citizens in Thessalonica leading to his excommunication by Ambrose. The chastened emperor took Ambrose's rebuke to heart, publicly repenting of the massacre and doing penance for the murders. “Nor was there afterwards a day on which he did not grieve for his mistake,� Ambrose himself noted when he spoke at the emperor's funeral. The rebuke spurred a profound change in Emperor Theodosius. He reconciled himself with the Church and the bishop, who attended to the emperor on his deathbed. St. Ambrose died in 397. His 23 years of diligent service had turned a deeply troubled diocese into an exemplary outpost for the faith. His writings remained an important point of reference for the Church, well into the medieval era and beyond. St. Ambrose has been named one of the “holy fathers� of the Church, whose teaching all bishops should “in every way follow.�
