The Roman Catholic Church's beatification of an Oklahoma priest killed during a mission in Guatemala more than three decades ago will be broadcast live on the Global Catholic Network.

The Rev. Stanley Rother is scheduled to be beatified during a Sept. 23 ceremony at the Cox Convention Center in Oklahoma City. A documentary on Rother's life and the ceremony will be broadcast on EWTN Global Catholic Network.

Rother was killed in 1981 during Guatemala's civil war after spending 13 years on a mission in that country.

The Archdiocese of Oklahoma City opened Rother's cause for beatification in 2007, at the request of his parishioners in Guatemala. Pope Francis put the American priest on the path to possible sainthood by declaring him a martyr in December.
