Prayer to Our Lady of the 

Immaculate Conception

O most Holy Virgin, immaculate in body
and spirit, look kindly on me as I implore
your powerful intercession.

O most Holy Mother, receive my prayers
as I present them to God.

Diocesan Information

Set Ablaze is a two-year comprehensive structural and pastoral planning process that will enable the Diocese of Sioux Falls to move from a position of slow decline to a position of growth—growth through missionary discipleship. Our goal is to discern how to best align the gifts of our priests, deacons, religious and lay faithful, along with our resources (human, physical and financial), so that we might see a resurgence of vibrant parishes, reenergized priests and leaders, and Catholics Set Ablaze with the love of God.
