Archbasilica of St. John Lateran
Christian teaching states that Christ ascended into heaven corporeally. Therefore, the only parts of his body available for veneration are those obtained prior to the Ascension. At various points in history, a number of churches in Europe have claimed to possess the Holy Prepuce, Jesus' foreskin from his Circumcision. A section of the Holy Umbilical Cord believed to remain from the birth of Christ is currently in the Archbasilica of St. John Lateran.
