The Knights of Columbus has established a Guild to advance the cause for canonization of their founder, Father Michael McGivney. The Guild gathers evidence on Father McGivney's life and character, collects information about favors people have received as the result of Father McGivney's intercession, promotes Father McGivney's cause for canonization, and offers spiritual benefits to its members.

Those devoted to Father McGivney are encouraged to join the Guild and regularly say the prayer for his canonization. Members participate in the Guild's spiritual works, pray for Father McGivney's canonization, report favors received, and in general assist in the advancement of the cause. Membership is open free of charge to individuals and households, but not to groups. Members may make tax-deductible contributions to assist in the Guild's work, but this is by no means required.

Father Gabriel B. O'Donnell, OP serves as Postulator for the Cause of Father McGivney and directs the Guild.
