The Aquinas Lecture given at Blackfriars, Cambridge on 29 January 1990.
1. Telling the time
By current standards, St Thomas Aquinas did not have very much to say about time, and even less to say about Friday, Saturday, or Sunday. When discussing the commandments, however, he did say something rather interesting about the Sabbath. Human beings, he tells us, owe a threefold duty to the head of their community: a duty of faithfulness or single-hearted loyalty, of reverence, and of service. This threefold duty is, according to St Thomas, the subject-matter of the commands to worship only God, to refrain from taking his name in vain, and to keep the sabbath holy. It is, he says, the servant’s duty to repay through service the good things received from his lord. But what we have received from this Lord, the Creator, is—everything. Hence the command to sanctify the sabbath in grateful remembrance of the creation of the world: ‘sanctifica(re) sabbat(um) in memoriam creationis rerum’. In due course, I shall return to this suggestion that it is in keeping our very createdness in mind that we keep the Sabbath holy. But, first, I want to reflect on what is entailed in learning how to pray.
But surely, you may say, we know how to pray? Jesus taught us how to pray: he taught us to say ‘Our Father ...’.
But do we really know how to say ‘Our Father’ here and now, in this place, at this time?
