The biographical sources are unreliable, being essentially a catalogue of miracles. There is no reason, however, to doubt that he was a saint: devotion to him started shortly after his death, when many people who had known him were still alive. He is patron saint of Madrid.

  Blessed Andrew was born in 1375 at Saint Maximin, France, and received the Dominican habit at the priory of St. Mary Magdalene there. He was outstanding for his teaching, for his preaching throughout Provence, and for his zeal in restoring regular observance. In addition he exercised his talents as an artist in many of the Dominican churches of southern France. He died at Aix-en-Provence on May 15, 1450.

  Blessed Giles was born at Vaozela, near Coimbra, Portugal, about the year 1184. Although destined for a church career by his father, Giles was more attracted by medicine which he studied and taught at Paris. According to tradition he was converted from a dissolute life through the intervention of the Blessed Virgin. He entered the newly founded Order of Preachers at Valencia around 1224 and became a celebrated preacher and an able superior. Noted for his humble service to his brethren, he died at Santarem on May 14, 1265.

  Whenever we take up a Bible we touch Irenaeus’s work, for he played a decisive role in fixing the canon of the New Testament. It is easy for people nowadays to think of Scripture – and the New Testament in particular – as the basis of the Church, but harder to remember that it was the Church itself that had to agree, early on, about what was scriptural and what was not. Before Irenaeus, there was vague general agreement on what scripture was, but a system based on this kind of common consent was too weak. As dissensions and heresies arose, reference to scripture was the obvious way of trying to settle what the truth really was, but in the absence of an agreed canon of scripture it was all too easy to attack one’s opponent’s arguments by saying that his texts were corrupt or unscriptural; and easy, too, to do a little fine-tuning of texts on one’s own behalf. Irenaeus not only established a canon which is almost identical to our present one, but also gave reasoned arguments for each inclusion and exclusion.

  Irenaeus also wrote a major work, Against the Heresies, which in the course of denying what the Christian faith is not, effectively asserts what it is. The majority of this work was lost for many centuries and only rediscovered in a monastery on Mount Athos in 1842. Many passages from it are used in the Office of Readings.
