Holy Lance
The Holy Lance, also known as the Lance of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, according to the Gospel of John, is the lance that pierced the side of Jesus as he hung on the cross.
Commemoration of the Passion of Christ
Whilst the feast in honour of the instruments of Christ's Passion—the Holy Cross, Lance, Nails, and Crown of Thorns—called "Arma Christi", originated during the Middle Ages, this commemoration is of more recent origin. It appears for the first time in the Breviary of Meissen (1517) as a "festum simplex" for 15 November. The same Breviary has a feast of the Holy Face for 15 January and of the Holy Name for 15 March.
