Longinus Lance :

The Longinus Lance is named for a roman soldier named Longinus. In biblical times, after someone had been crucified for awhile, a soldier ran his spear through his side to make sure if he were dead. If not, the soldier then broke his legs. According to tradition, the name of the centurion at the Crucifixion who acknowledged Christ as "the son of God" (Matt. 27:54; Mark 15:39; Luke 23:47) was Longinus.
This centurion is also identified as the soldier who "pierced His side with a lance" (John 19:34), probably because the name is derived from the Greek word longche, meaning a lance. Untrustworthy legend exemplified by the Golden Legend says that the blood pouring from Christ's side immediately healed him of incipient blindness.
Therefore, he was converted, left the army, took instruction from the Apostles, and then became a monk (centuries before there were monasteries) at Caesarea, Cappadocia, allegedly his homeland.
The story continues that he was arrested for his faith and tortured. His teeth were knocked out and tongue plucked. He is said to have destroyed idols with a nearby axe in the presence of the governor who was trying him. From the broken idols came evil spirits that possessed, maddened, and blinded the governor. Longinus told his judge that he would be healed only after his own death. So, Longinus was immediately beheaded; whereupon the governor was healed and converted.
That makes the Longinus Lance a crucial element in SEELE's plans. The lance is used to immobilize Lilith in the Central Dogma, her blood (!) is used as LCL for connecting the pilots to their respective Evangelions, the Lance serves as catalyst in the Human Instrumentality Project !
