Specifics of Our Parish Family

church_240x200We are a Parish of the Diocese of Rockford. The Diocese of Rockford continues to the Wisconsin border to our North, South to the Peoria Diocese, East to the Dioceses of Chicago and Joliet, and West to the Mississippi River. Saint Margaret Mary is a growing community which includes parts of Algonquin, parts of Lake in the Hills, and parts of Barrington Hills. We are a Stewardship Parish who believes that belonging to a Parish Family involves more than just attending Mass. God blesses us and gives us our Time, our Talents and our Treasure. Our Parish prides itself on being a “giving” parish. In thanksgiving of all that God has given to us, each parishioner is asked to share a portion of their gifts of Time, Talent and Treasure for the growth and development of God’s Kingdom. The many ministries of our Parish Family, as well as, the contributions of treasure allow the parish to do the work of God both within and without the parish. This “giving of ourselves” makes us a Stewardship Parish. If you are interested in giving of yourself at this time, please visit our Ministries page.

Our Sanctuary: The Meaning of the Cross of San Damiano

St. Margaret Mary is blessed to have a replica of the famed Cross of San Damiano hanging within our sanctuary (pictured at right). Have you every wondered what all of the images mean and the significance of the cross itself? The original cross was fashioned around the year 1100 and hangs in Santa Chiara Church in Assisi. When in 1257, the Poor Clares moved to Sanata Chiara, they took the original San Damiano Cross with them and still guard it with great reverence . Please click below for a PDF explaining the Cross of San Damiano.
