In recent decades there has been a notable renewal of interest in St Isaac the Syrian, a seventh-century master of the ascetic life. This selection of short sayings is part of Dr Brock’s work on a fuller, long-neglected manuscript which he is making available to English readers. Each sentence holds the mind steadily in the light of a truth about the spiritual life. St Isaac’s vivid images drawn directly from nature, husbandry and general human experience speak for themselves and draw us to penitence and prayer.
