Boston.com reports that a vial of the late Pope John Paul II's blood will be on display at the Holy Cross Cathedral in Boston's South End which will kick-off a nationwide tour.

It is on loan from the John Paul II Shrine in Washington DC.

Pope John Paul II is one of the most beloved Popes ever and was even canonized this past April. He traveled to over 120 countries during his time as Pope from 1978 to his death in 2005.

This vial is considered a relic in the Catholic religion and it's a pretty big deal that it's coming to Boston.

There are 3 classes of relics for Catholics. The first class is from the body of a saint (like the vial that is going to be on display). The second class is an object used by the saint and the third is an object that the saint touched.
