nature of genuine adiaphora, which it defined as church rites that are "neither commanded nor forbidden in the Word of God". However, the Concord added believers should not yield even in matters of adiaphora when these are being forced upon them by the "enemies of God's Word". The Lutheran Augsburg Confession states that the true unity of the Church is enough to allow for agreement, concerning the doctrine of the Gospel and the administration of the Sacraments. It also posits that merely human traditions, namely extrabiblical rites or ceremonies, need not be the same across all congregations. Puritanism The Westminster Confession of Faith, a confession of faith written by the Puritans, which after the English Civil War was rejected by the Anglicans, distinguishes between elements or acts of worship (worship proper) and the circumstances of worship. The elements of worship must be limited to what has positive warrant in Scripture, a doctrine known as the regulative principle of worship. In this framework, the elements of worship have included praise (the words and manner of music), prayer, preaching and teaching from the Bible, the taking of vows, and the two sacraments of baptism and the Lord's Supper, while the circumstances of worship have included the building and its necessary furniture and the time of day for worship. The circumstances of worship are considered adiaphora, although they must be done for edification and to promote peace and order (compare ; ). According to the Westminster Confession 20.2, the conscience is left free in general belief and behavior within the realm of whatever is not "contrary to the Word". However, specifically concerning worship and religious faith, the conscience is free from whatever is "besides" Scripture; that is, it is free to worship and believe only according to whatever has positive warrant in Scripture. Presbyterians who have subscribed to the Westminster Confession, for instance, sometimes considered the questions of musical instruments and of the singing of hymns (as opposed to exclusive psalmody) not drawn directly from the Bible as related to the elements of worship, not optional circumstances, and for this reason they rejected musical instruments and hymns because they believed they were neither commanded by scripture nor deduced by good and necessary consequence from it. Adherence to such a position is rare among modern Presbyterians, however. The Puritan position on worship is thus in line with the common saying regarding adiaphora: "In necessary
