The final breach between the English provinces and Western Catholic Europe is pinpointed by the Feast of the Nativity of S John Baptist, June 24 in 1559. On that day, it became illegal, according to statute law, for that Liturgy to be celebrated which had formed and sanctified the peoples of England since 596. From this rupture, affecting every parish church in the kingdom, flowed all the other discontinuities which have marred and corrupted our national life since that day.
I'm sure readers will be able to think of their own ideas for an appropriate way to commemorate that day. For myself, I cannot think of anything better than to make absolutely sure that - whatever Eucharistic Prayer one might normally use - on that day one uses the Roman First Eucharistic Prayer: the prayer brought here by S Augustine and used daily for nearly a millennium.
Wise words from the great Anglican liturgist G G Willis: In liturgical quality, both of language and structure, it excells all other Eucharistic rites...it is the best one available ... It is time for the Church of England to forsake inveterate prejudices derived from Reformation Protestantism, and to accomplish something in liturgical revision which would give unity and peace on the basis of an ancient and well-tried form of prayer.
