This solemnity has ancient roots, stemming from the celebration of the anniversary of “all the martyrs” early in the 4th century. The festival became more popular when, in the 7th century, Pope Boniface IV brought wagon loads of bones into the Pantheon in Rome, rededicating that pagan temple as a Christian church. Since the 9th century, November 1st has been the date given to this feast.
On this day, as we remember the holiness of particular saints who have modeled grace for us, we seek their intercession. Our Opening Prayer at the Mass states, “Today we rejoice in the holy men and women of every time and place. May their prayers bring us Your forgiveness and love.” This certainly brings the historical reality of the saints into our present reality. This living experience causes us to express our joy. In our liturgical celebration at this feast, we are participating in the holiness of the saints, who are in union with us (Communion of Saints) and actively share in our worship, as together we await the day of the Lord—a very important day indeed.
