Calvin believes that singing poetry is one of the four main behaviors of church worship. He regards singing poetry as an extension of prayer. Similarly, Calvin believes that collective poetry will subdue people's fallen hearts, restrain people's capricious feelings, and make people embark on the path of piety. Just like sermons and sacraments, poetry can train people's inner feelings in faith schools and promote people to come before God. It will also carry forward the effect of Tao in people's hearts and multiply the spiritual power of the church. Under the guidance of the Holy Spirit, chanting poems can adjust the hearts of believers and make them tend to the glory of God.
For centuries, the Geneva Poetry Festival has been an indispensable part of Calvinism worship. It set a standard in the later poetry books of the reformed church in France, as well as in the poetry books of the reformed churches in Britain, Holland and Hungary. As a spiritual work, it has ignited the hearts of thousands of people, but those who recite this collection of poems know that its power lies not in the book or its words, but in the Holy Spirit engraving these words in their hearts.
Geneva poetry promotes piety by inspiring spiritual practice based on holy words. This practice is collective and ritualistic, breaking the separation between etiquette and life. Calvinists will not only sing freely in their own churches, but also in their families and jobs, and in the streets of Kaminowada. Hartley Hall wrote: Poetry and its solemn tunes have obviously become the core and soul of Reformed piety, whether in the form of biblical scripture or rhythmic poetry.
