lesser sign

The "lesser sign" of the cross is a Christian ritual used for blessing. In the Latin rite, it's performed with the thumb on the forehead, lips, and breast, often before the Gospel reading during mass. This gesture, with roots in ancient Christian tradition, is explained by St. Cyprian as a reference to Christ's death on the cross. While the great sign uses five fingers for a broader blessing, the lesser sign is a more focused, personal act of devotion. This ritual, like other sacraments, is considered an outward sign instituted by Christ that conveys inner grace.12
