In the early church, those considered to be saints were martyrs. As time went on and the persecutions stopped, the church realized that one could be a saint even though they were not martyred. Pope Boniface IV in the 7th century, loaded 28 carts of bones from the catacombs and placed them beneath the Pantheon (a Roman temple dedicated to all the “gods”) He rededicated the building as a Christian Church. Saints were declared so by the local bishops. It is only within the last 5 centuries or so that the long process of investigation to declare a saint has been in effect. Eventually, Nov. 1 was chosen as the day to honor all the saints not just the ones “canonized” but all the faithful who are with God in heaven.
