Historic Reformed churches worship the Lord in simplicity. That is, Reformed churches do not include ceremonies, festivals, crucifixes, processions, incense, relics, images, vestments, altars, and so forth in their worship services. Reformed worship simply consists of the Word (read, preached, sung, confessed, prayed) and the sacraments (the Lord’s supper and baptism).
The main reason for the simplicity of Reformed worship is the teaching of Scripture. The Bible doesn’t command God’s New Covenant people to worship him with all the images and vestments and ceremonies. The Reformers believed that the external ceremonies and images didn’t elevate the mind to God, but domesticated God and therefore were idolatrous. Furthermore, they said that all these non-biblical extras in worship throw a fog over the gospel. Simple worship, therefore, means the gospel will not be obscured. In 1560 the Reformer Guillaume Farel explained it like this:
The Church should be decorated and adorned with Jesus Christ and the Word of his gospel and his holy sacraments. This great Sun of Righteousness, Jesus Christ, and the light of his gospel, have nothing to do with our burning torches and our candles and candelabras. God has instead ordained that by true preaching and by the holy sacraments practiced in their simplicity this light might be manifested and illumine us with all glory.
Similarly, Theodore Beza preached the following in 1585:
[God’s house is not a place] that we enter to see the beautiful shapes of vaults and pillars, or to admire the splendor of gold and silver and precious stones. Nor is it a place that we visit in order to fill our ears with the signing of choirs and the music of organs. Rather it is a place where the pure Word of God is clearly preached in the presence of each person, with words of exhortation, consolation, warning, and censure necessary for salvation.
In other words, the Reformers wanted worship to be ordered according to the Word and centered on the gospel. They wanted to keep it simple so God’s word and his gospel would clearly be front and center. In that way, he alone would receive all the glory, honor, and praise. ‘Soli Dei Gloria’ goes hand in hand with Reformed worship!
