ADA, Okla. (AP) — East Central University in Oklahoma is removing Bibles and crosses from its on-campus chapel after receiving a complaint from a group that advocates for the separation of church and state.

The public university is in Ada, about 65 miles southeast of Oklahoma City. University President Katricia Pierson said in a statement Thursday that the school chose to remove the religious items after receiving a letter from Americans United for the Separation of Church and State.

She says the school is “looking at the feasibility” of removing the cross from atop the steeple of the chapel.

The university says the Kathryn P. Boswell Memorial Chapel opened in 1957 and is available for use by all faiths.
