Brady was elected Bishop Coadjutor of the
Diocese of Fond du Lac on November 11, 1952. His consecration took place February 24, 1953, where Bishop
Harwood Sturtevant served as the Chief Consecrator. The diocese was basically a rural/town missionary diocese with 21 missions and 18 parishes. Bishop Brady served as Coadjutor for four years, during which time he lived in
Stevens Point, Wisconsin since Bishop Sturtevant assigned him the parishes in the area then known as the Western Convocation in addition to all the missions of the diocese. On the retirement of Bishop Sturtevant, Brady's installation as
diocesan took place at the
Cathedral of St. Paul in Fond du Lac, Wisconsin on January 6, 1957. One process Brady immediately addressed had to do with diocesan investments. Bishop Sturtevant had handled these directly in consultation with diocesan treasurer,
Andre Perry. Working with the Trustees of the Diocese, a decision was made to sell all of the investments currently held by the Diocese and pool the money as a common trust. Congregations were also able to participate in the pooling of these funds to gain the advantage that comes from larger pools of assets. In 1959, Bishop Brady formed the Apostolate Committee which discussed all aspects of the diocesan life. One member suggested a diocesan festival, and so began, on the last Sunday in June, 1960 the Eucharistic Festival with a glorious procession, Benediction of the Blessed Sacrament, and a hot-dog party after the service. The Eucharist Festival continues to this day. When Bishop Brady came to the Diocese, most of the congregation used Morning Prayer on Sunday mornings. He worked to set the character for priests to know that each day, especially Sunday, was centered in the Holy Eucharist. Bishop Brady also held many gatherings around the diocese with the clergy and lay people to discuss various subjects including vocations, and Christian response in a civil world. These gatherings stimulated thinking, drew people closer together where they learned to respect each other's ideas. In the early 1960s, a diocesan-wide fundraising campaign was held that raised over $700,000, benefiting many congregations throughout the diocese over the years by gifts and loans. Brady also served for a time as Chaplain-General of the Order of St. Vincent, the National Guild for Acolytes In 1974, Bishop Brady was one of four bishops who filed charges against bishops who participated in a service in which 11 women deacons were intended to be ordained to the priesthood in Philadelphia, Pennsylvania on July 29, 1974. While these ordinations were found to be irregular, the Episcopal Church did eventually allow the ordination of women to the priesthood. ==Retirement==
