Relics of the Wood from the True Cross are considered one of the most sacred and powerful relics in Christianity. Its use in a Catholic exorcism holds deep spiritual significance within the context of the Catholic faith. The relic of the True Cross is often employed as a symbol of Christ's ultimate triumph over evil and as a source of divine protection and intervention. The exorcist may hold the relic or use it to make the sign of the cross, invoking the name of Christ and the power of His sacrifice. This act is believed to repel the malevolent forces and demons afflicting the possessed individual. The relic is a tangible connection to the redemptive power of Christ's sacrifice, serving as a reminder of His victory over sin and darkness. Its presence in the exorcism ritual underscores the belief that through faith and prayer, the forces of evil can be cast out and the person being exorcised can find deliverance and healing.
According to the New Testament, a woven Crown of Thorns was placed on the head of Jesus during the events leading up to his crucifixion. It was one of the instruments of the Passion, employed by Jesus' captors both to cause him pain and to mock his claim of authority. It is mentioned in the gospels of Matthew (Matthew 27:29), Mark (Mark 15:17) and John (John 19:2, 19:5), and is often alluded to by the early Church Fathers, such as Clement of Alexandria, Origen and others, along with being referenced in the apocryphal Gospel of Peter. Since at least around the year 400 AD, a relic of the Crown of Thorns has been venerated. In 1238, the Latin Emperor Baldwin II of Constantinople yielded the relic to French King Louis IX.
