The title of this post comes from today’s section of the Rule of St Benedict. It is the last tool of good works named in the chapter and one on which most of us rely all our life (RB 4.76). This morning, with the folly of Brexit again before our eyes and the Church as much in turmoil as ever, it is something to cling to, like a rock. But rocks are not only places of refuge: they can also provide the footing from which to launch ourselves into the deep. The mercy of God is like that, too. It upholds us in times of trouble and propels us forward when we need to go further into the mystery of God and our own vocation. It takes thought, prayer and humility to decide which is which. Let us pray that we may each discern correctly what is being asked of us today.
