Schuller told the Orange County Register Wednesday that the statement goes against the principles of tolerance, acceptance and positive thinking on which he built his 50-year-old ministry.
The Register says Schuller contacted the newspaper to say he did not know the covenant existed and would have personally never approved it.
The document says choir members should commit to being Christians by following the Bible in every way and understand that God intends sex to be between married heterosexuals.
Several choir members said they were upset by the statements made in the covenant and would refuse to sign it.
