Holy Lance in the context of "Imperial Regalia"

Jesus was put to death by being nailed on an execution device made by the Romans, commonly named as a cross (Latin: crux). The instrument of crucifixion is taken to be an upright wooden beam to which was added a transverse wooden beam, thus forming a "cruciform" or T-shaped structure. His crucifixion occurred in 1st-century Judaea, most likely in AD 30 or AD 33. The event is described in the four canonical gospels, referred to in the New Testament epistles, and later attested to by other ancient sources. Scholars nearly universally accept the historicity of Jesus' crucifixion, although there is no consensus on the details. According to the canonical gospels, Jesus was arrested and tried by the Sanhedrin, and then sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans.

Jesus was stripped of his clothing and offered vinegar mixed with myrrh or gall (likely posca) to drink. At Golgotha, he was then hung between two convicted thieves and, according to the Gospel of Mark, was crucified at the third hour (9 a.m.), and died by the ninth hour of the day (at around 3:00 p.m.). During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" which, according to the Gospel of John, was written in three languages (Hebrew, Latin, and Greek). They then divided his garments among themselves and cast lots for his seamless robe, according to the Gospel of John. The Gospel of John also states that, after Jesus' death, one soldier (named in extra-Biblical tradition as Longinus) pierced his side with a spear to be certain that he had died, then blood and water gushed from the wound. The Bible describes seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred.

Blood of Christ, also known as the Most Precious Blood, in Christian theology refers to the physical blood actually shed by Jesus Christ primarily on the Cross, and the salvation which Christianity teaches was accomplished thereby, or the sacramental blood (wine) present in the Eucharist or Lord's Supper, that some Christian denominations believe to be the same blood of Christ shed on the Cross.

The Catholic Church, Eastern Orthodox Church, the Oriental Orthodox churches, the Assyrian and Ancient Churches of the East, and Lutherans, together with high church Anglicans, know this as the real presence of Christ in the Eucharist. The Catholic Church uses the term transubstantiation to describe the change of the bread and wine into the body and blood of Christ. The Eastern Orthodox Churches used the same term to describe the change, as in the decrees of the 1672 Synod of Jerusalem, and the Catechism of St. Philaret (Drozdov) of Moscow.

Longinus (Greek: Λογγίνος) is the name of the Roman soldier who pierced the side of Jesus with a lance, who in apostolic and some modern Christian traditions is described as a convert to Christianity. His name first appeared in the apocryphal Gospel of Nicodemus. The lance is called in Catholic Christianity the "Holy Lance" (lancea) and the story is related in the Gospel of John during the Crucifixion. This act is said to have created the last of the Five Holy Wounds of Christ.

This person, unnamed in the Gospels, is further identified in some versions of the story as the centurion present at the Crucifixion, who said that Jesus was the son of God, so he is considered as one of the first Christians and Roman converts. Longinus's legend grew over the years to the point that he was said to have converted to Christianity after the Crucifixion, and he is traditionally venerated as a saint in the Roman Catholic Church, Eastern Orthodox Church, and several other Christian communions.

The Church of Cassian (Arabic: القسيان), also called the Church of St. Peter (gr. Hagios Petros), was the Cathedral church of Patriarch of Antioch during late antiquity and the Middle Ages. The church is not to be mistaken with the cave church called St. Peter.

A version of the Holy Lance was found in the treasury of the cathedral in 1098, by the forces of the First Crusade. In 1190, the cathedral became the burial place of Frederick Barbarossa. In 1268, the cathedral was burned by Baybars during his sack of Antioch.
