“The “Order Principle” in 1 Corinthians 14 means that Christian worship should be structured in such a way that instruction is clear, intelligibility is essential, ordained roles and teaching offices are maintained, all the saints are built up in the faith, love and peace are abundant, and God is glorified in all things.

It is for this reason that Christians have historically ordered their meetings and services around a well-structured service that takes believers through all of the essential components or elements of a full, robust worship experience. We might speak of this as the “liturgy,” from the Latin word liturgia meaning “service.” A well-ordered liturgy takes the gathered saints through an incredibly beautiful journey in which practically every aspect of the history of redemption is recalled and applied.

Although there is great variation in ancient, historic, Protestant, and even Reformed liturgies of worship, certain basic elements are usually present somewhere in the service. These include: an acknowledgment of God as Creator, a confession of the fallen state of man, a rehearsal of the Law of God, the proclaiming of the saving Gospel of Christ, the tangible celebration of the sacraments, and the blessing of the Christian life.

In other words, the service moves through the history of redemption: Creation, Fall, Redemption, and Consummation. Worship is therefore Trinitarian. God the Father, God the Son, and God the Holy Spirit are each extolled and praised.”
