The following is excerpted from The Church's Year of Grace, by Pius Parsch.
These seven men were the founders of the Servite Order, a community instituted for the special purpose of cultivating the spirit of penance and contemplating the passion of Christ and Mary's Seven Sorrows. Due to the spirit of humility cherished by the members of the Order, their accomplishments are not too widely known. But in the field of home missions great things are to their credit, and certainly they have benefited millions by arousing devotion to the Mother of Sorrows.
The Breviary tells us that in the midst of the party strife during the thirteenth century, God called seven men from the nobility of Florence. In the year 1233 they met and prayed together most fervently. The Blessed Mother appeared to each of them individually and urged them to begin a more perfect life. Disregarding birth and wealth, in sackcloth under shabby and well-worn clothing they withdrew to a small building in the country. It was September 8, selected so that they might begin to live a more holy life on the very day when the Mother of God began to live her holy life.
Soon after, when the seven were begging alms from door to door in the streets of Florence, they suddenly heard children's voices calling to them, "Servants of holy Mary." Among these children was St. Philip Benizi, then just five months old. Hereafter they were known by this name, first heard from the lips of children. In the course of time they retired into solitude on Monte Senario and gave themselves wholly to contemplation and penance. Leo XIII canonized the Holy Founders and introduced today's feast in 1888.
O Almighty God, who hast compassed us about with so great a cloud of witnesses: Grant that we, encouraged by the good examples of the Seven Holy Founders of the Servites, may persevere in running the race that is set before us, until at length, through thy mercy, we may with them attain to thine eternal joy; through Jesus Christ, the author and perfecter of our faith, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever. Amen.
