Yes, it is absolutely against the Will of God to be tolerant of other religions. This is clear in the Ten Commandments and in the New Testament.
Jesus Christ constantly attacked Jewish religious leaders in the New Testament who refused to believe in Jesus Christ as the Messiah (Christianity).
Apostles of Jesus Christ were arrested by the democratic federal government, because they opposed religious tolerance and religious liberty that was by law required by the federal government (Roman democracy).
The Old Testament never endorsed Democracy even though Greek democracy existed as a political value and was practiced during its time.
The New Testament never endorsed Democracy even though Jesus Christ and St. Paul lived while Democracy was practiced by the Roman Empire. In fact, every one of the the apostles of Jesus Christ (except the traitor Judas Iscariot) was arrested by the Democracy because the apostles of Christ stood against religious pluralism that is so important to Democracy.
The Holy Bible emphasizes that Christianity is the only way to salvation. The Holy Bible attacks other religions. The apostles of Jesus Christ attacked other religions, such as Judaism and Pagan religions of the Roman Empire. Democracy used its resources to arrest the apostles of Jesus Christ who stood against religious tolerance that is so important in a Democracy.
