Author of one of the four Gospels and of the Acts of the Apostles, St. Luke was a disciple of St. Paul, whom he followed in his apostolic travels for twenty-five years. A native of Antioch, he was a doctor, but also a painter.
Converted by St. Paul, he endeavored to gather from the other Apostles and the first Christian communities testimonies and traditions about the life and teaching of Christ. St. Paul praises it in the second epistle to the Corinthians, where the Apostle of the Nations salutes "the brother of whom all the churches praise for his zeal to preach the Gospel (...), who has been chosen to be our traveling companion in this work of charity to which we work for the glory of the Lord ... "(8, 18-19).
In contact with the Mother of God whose features he painted, he wrote the stories of the childhood of Christ. He also echoed the most touching parables that Our Lord proposed to His disciples to teach them about the Kingdom of God, like those of the good Samaritan or the prodigal son. This is why Dante calls him "the historian of the leniency of Christ".
After the death of St. Paul, he traveled through Italy, Gaul, then Dalmatia and Macedonia. He died probably martyr in Bithynia, at the age of 84 years.
The animal that distinguishes him from the evangelists is the ox or the bull, an animal destined for sacrifice. Indeed, his Gospel begins with the story of Zechariah, the priest priest, when he officiates in the Temple. Husband of St. Elizabeth, he will become the father of St. John the Baptist, the Precursor.
