Holy Lance
The name of the soldier who pierced Christ's side with a "lonchē" is not given in the Gospel of John, but in the oldest known references to the legend, the apocryphal Gospel of Nicodemus appended to late manuscripts of the 4th century "Acts of Pilate", the soldier is identified as a centurion and called Longinus (making the spear's Latin name "Lancea Longini").
Spear (liturgy)
The Spear is one of the Sacred Vessels usually kept on the Table of Oblation (Prothesis), where the bread and wine are prepared for the Eucharist. Often when a Chalice and Diskos (Paten) are made, an Asterisk and a Spoon and Spear will be made to match them. The Spear is normally made of precious metal (or at least plated with silver and/or gold), has a point sharp enough to cut the bread, and will often have a cross at the end of the handle.
