TULSA, Okla. (AP) — Oral Roberts returned to his namesake university Monday and denied the lurid accusations that have threatened to engulf the school, telling students and employees in a chapel service that "the devil is not going to steal ORU."

Making his first visit to Oral Roberts University in three years, Roberts said at the service that his son Richard Roberts, who took a leave of absence as the school's president last week, eventually will return to his position, the Tulsa World reported.

Three former professors sued the university Oct. 2 for wrongful termination, claiming they were dismissed after they turned over to the board of regents a copy of a report documenting moral and ethical lapses on the part of Richard Roberts and his family.

Oral Roberts, 89, was given a standing ovation.
