Following the Jewish rite, Jesus was circumcised, which leaves the question of what became of his foreskin.

Very few articles have been written on the topic of the Holy Foreskin, partly because in the year 1900 the Roman Catholic Church threatened to excommunicate anyone who did so.

However, Robert Palazzo bravely did his research and his article “The Veneration of the Sacred Foreskin(s) of Baby Jesus: A Documentary Analysis,” offers some interesting details about this relic.

By the eleventh century, several churches in Europe explained they had the Holy Foreskin.

[In] the time of Charlemagne an angel gave the relic to the Emperor. In 1421, it was even sent to Cathernine of Valois in England, so that it would bring good fortune (and a pregnancy) to her marriage with Henry V.

The last place known to have publicly shown the Holy Foreskin was the Italian village of Calcata, which lies 30 miles north of Rome.

Then in 1983, it mysteriously disappeared. Many locals believe that it was the Vatican that was responsible for taking away their precious relic.
