Monsignor William Lynn says he did everything within his power to get accused priests out of parishes and into treatment.
He admits it wasn't enough for one victim who was sexually assaulted by the Rev. Edward Avery - years after complaints about Avery had reached the archdiocese. Lynn says he's sorry for that.
Avery is in prison after pleading guilty to the 1999 assault.
Lynn is charged with child endangerment and conspiracy. Defense lawyers call him a scapegoat for the archdiocese.
Lynn says Cardinal Anthony Bevilacqua would only remove diagnosed pedophiles.
Asked Tuesday if keeping predators in ministry was immoral, Lynn replied, "You want me to answer for the whole church?"
