After the second cycle of confession before God, grace is declared through the reading and response of Scripture. Old and New Testament portions are read as first and second lessons. After each reading, the congregation stands and announces the grace of God by singing Scripture. This is all done out of great reverence for God and His Word. All churches have certain beliefs even though they might deny that they have a creed.
Creeds are unavoidable.
The historic church has always built its creeds around the Holy Trinity. In both of the standard creeds, the reader will notice this threefold division around Father, Son, and Holy Spirit. This is a creedal expression of faith. Notice that the first response of faith was in the form of prayer. Now it is by means of a creed.
