Sheehan reconsecrated St. Jude Thaddeus Church on Wednesday by sprinkling holy water and spreading incense through the building. The move was part of a Catholic ritual required after a sacrilege has been committed at a church.
Lawrence Capener, 24, attacked a choir leader at the church at the end of Sunday Mass, police said. Two other people were stabbed when they tried to stop him, according to authorities.
Capener is charged with aggravated battery and was being held on $250,000 bail.
Sheehan told KRQE-TV ( http://bit.ly/12rsReD) he doesn't expect stepped-up security to be with the church for long or at parishes throughout the state.
"We can't change everything to make the world perfect," Sheehan said. "It's just the human reality that there's limits to what you can do to protect society. It's the first time in 30 years being a bishop that such a terrible thing has happened. I don't think it will happen again."
Parishioners said they rarely saw Capener attend services but were aware that his mother is active in the church, which is on the city's Westside.
