The Cathedral Parish of the Diocese of Madison, consists of Holy Redeemer Catholic Church, St. Patrick Catholic Church and the former St. Raphael Cathedral.​

When the Diocese of Madison was formed in 1946, St. Raphael Church was chosen as the Cathedral. The Cathedral Parish has a long history of community support, including opening its basement as a shelter for the homeless. It continues to be a hub of stewardship in the diocese.

In 2005, the St. Raphael Cathedral was lost to an arson fire. After the fire, the three parishes around the Capitol Square were linked under the care of a single pastor.

 A gift to the Cathedral Parish of St. Raphael Endowment supports the Cathedral Parish with assistance to parish life and capital maintenance.
