The primary purpose of this society is to the Glory of God in the example of the Blessed Virgin Mary. All women of St. John Parish are members of the Altar & Rosary Society and are invited to be active members. Members share responsibility for the care of the church interior, as well as co-ordinate donations and provide for flowers. There are various activities which raise funds for the group. The Altar & Rosary Society provides occasions for fellowship and spiritual growth. The Altar & Rosary Society is affiliated with the National and Diocesan Council of Catholic Women.
Meetings are held the 3rd Monday of the month (except December) at 6:00 p.m. in Room 3 of the St. John Family Center.
