O God, you called your servant Margaret to an earthly throne that she might advance your heavenly kingdom, and gave her zeal for your Church and love for your people: Mercifully grant that we who commemorate her this day may be fruitful in good works, and attain to the glorious crown of your saints; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God for ever and ever. Amen.
