Quick Summary

The "great sign" refers to a specific Christian ritual known as the sign of the cross. This gesture is used by Christians to bless themselves, others, or objects. Its origins are traced back to the 3rd century, with St. Cyprian linking it to Christ's death on the cross.

In the Latin rite, the great sign is made with the five fingers outstretched, symbolizing the five wounds of Christ. This gesture is performed on the forehead, breast, and shoulders, moving from left to right. It is often used by a priest when blessing the congregation with the Trinitarian invocation: "In the name of the Father and of the Son and of the Holy Spirit."1
