Passover celebrates the freeing of the Jews from slavery; Shavuot celebrates their becoming God’s holy people by the gift and acceptance of the Law; and the counting of the days to Shavuot symbolises their yearning for the Law.

  From a strictly practical point of view, Shavuot was a very good time for the Holy Spirit to come down and inspire the Apostles to preach to all nations because, being a pilgrimage festival, it was an occasion when Jerusalem was filled with pilgrims from many countries.

  Symbolically, the parallel with the Jews is exact. We are freed from the slavery of death and sin by Easter; with the Apostles, we spend some time as toddlers under the tutelage of the risen Jesus; and when he has left, the Spirit comes down on us and we become a Church.

  Boniface left England, never to return, and took the gospel to the heathen tribes of Germany, where he had great success. He himself was created Bishop of Mainz, and he founded or restored dioceses in Bavaria, Thuringia, and Franconia. In his later years he worked with King Pepin the Short to reform the Frankish church, and then, over seventy years old, set out to evangelize Friesland (part of modern Holland) where he was set upon and murdered, on 5 June 754.

  He is buried at Fulda, near Frankfurt, in the monastery he founded himself, and is honoured as the apostle of Germany.

  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.
