The victim is not a parishioner but reported that she was attacked by Rafael Venegas in September 2011 on the church grounds at 2017 Colorado Ave., the Santa Monica Police Department said.
Venegas was charged by the Santa Monica city attorney's office with one count of sexual battery and one count of furnishing alcohol to a minor under 21, police said in a statement.
Venegas, accompanied by his attorney, turned himself in Monday to authorities at the Police Department.
He was released from custody after posting $20,000 bail.
He is scheduled to be arraigned Friday in Division 147 at the LAX Courthouse.
