Several Christian denominations explicitly connect the dots. The Church of England, the Anglican Church of Canada, the Lutherans and the Eastern Orthodox all ring in the New Year with the Feast of the Circumcision.
No one is denying that Jesus was circumcised. Christian lore mentions a relic known as the holy foreskin. As with many relics, items believed to be the Holy Prepuce began to show up in Europe during the Middle Ages — in places we know today as Belgium, France, England, Italy and, of course, Israel. Churches, chapels and abbeys were built to house and celebrate the purported foreskins. Jewel-encrusted boxes were designed to protect them.
The author David Farley was unable to locate his target in Calcata, Italy, as the holy relic mysteriously disappeared in the early 1980s. Will the holy foreskin ever be found? Sadly, much like the Maltese Falcon, it has a penchant for disappearing, showing up elsewhere and disappearing yet again. But according to Vatican.com, the Archbasilica of St. John Lateran in Rome holds the remains of the Holy Umbilical Cord — so there’s hope.
