Bishop George Murry of the Roman Catholic Diocese of Youngstown was admitted to the Cleveland Clinic on Sunday to begin intensive chemotherapy for the next four weeks.

Murry, 69, has been diagnosed with a form of acute leukemia.

Murry, however, will continue to be informed of and involved in the day-to-day matters of the church and no leadership change is planned, diocese spokesman John Zuraw said.

“The bishop is still in control,” Zuraw said.

The diocese asked parishioners to keep the bishop in their prayers.

Murry’s doctors said he will not be permitted to receive visitors during his treatment, but the diocese said it will share regular updates on his health.

The diocese serves about 150,000 Catholics in Portage, Stark, Ashtabula, Columbiana, Mahoning and Trumbull counties.

Murry was 58 when he was selected to the post in 2007, becoming the first African-American to lead a Catholic diocese or archdiocese in the state.

Born in Camden, N.J., he was ordained a priest in 1979, a bishop in 1995, and served in leadership roles in Chicago and St. Thomas, Virgin Islands, before coming to Youngstown.

More recently, Murry was picked last fall to head a United States Conference of Catholic Bishops committee to address racism in society and the church.
