The event was investigated by the Bishop of Cambrai, who declared it authentic. The bloodstained corporal was preserved at the priory and became an important pilgrimage relic. The Augustinian canons who maintained the priory became custodians of the relic. The miracle is still commemorated annually, and the corporal remains on display for veneration.
