Singing was an important part of Christian worship. But were their songs accompanied with mechanical instruments or unaccompanied with mechanical instruments whenever they gathered for worship? This work combines the teachings of the New Testament and the voice of history to examine music in the worship of the church. The New Testament is very clear as to how Christians are to worship God in songs. The command is to sing. And the practice of the early church was congregational singing. The introduction of instrumental music and dancing in the churches are not the teachings of the New Testament. Similarly, as a matter of historical perspective, without exception, every commentator and church historian agree that the early church fulfilled her obligation to sing praises to God without the use of instrumental music. Instrumental music was added to Christians' worship after several years of the church's existence when men decided not to remain within the teachings of God.
