The Feast of St. Athanasius, Bishop and Doctor of the Church
is today. There is information on him here. He was one of the Venerable's favorite saints.

The revealed doctrine of the Incarnation exerted a stronger and a broader influence on Christians, as they more and more apprehended and mastered its meaning and its bearings. It is contained in the brief and simple declaration of St. John, "The Word was made flesh;" but it required century after century to spread it out in its fulness, and to imprint it energetically on the worship and practice of the Catholic people as well as on their faith. Athanasius was the first and the great teacher of it. He collected together the inspired notices scattered through David, Isaias, St. Paul, and St. John, and he engraved indelibly upon the imaginations of the faithful, as had never been before, that man is God, and God is man, that in Mary they meet, and that in this sense Mary is the centre of all things. He added nothing to what was known before, nothing to the popular and zealous faith that her Son was God; he has left behind him in his works no such definite passages about her as those of St. Irenæus or St. Epiphanius; but he brought the circumstances of the Incarnation home to men's minds, by the multiform evolutions of his analysis, and thereby secured it to us for ever from perversion.
