BBC did an article on Christian worship: Christian worship involves praising God in music and speech, readings from scripture, prayers of various sorts, a sermon, and various holy ceremonies (often called sacraments) such as the Eucharist. While worship is often thought of only as services in which Christians come together in a group, individual Christians can worship God on their own, and in any place. The Origins – Christian worship grew out of Jewish worship. Jesus Christ was a religious Jew who attended the synagogue and celebrated Jewish festivals, and his disciples were familiar with Jewish ritual and tradition.

The first obvious divergence from Judaism was making Sunday the holy day instead of Saturday driven by the Catholic Church in the 4th Century AD. Jesus’s promise to stay with his followers, fulfilled in the sending of the Holy Spirit, illuminated the development of Christian worship from early times. So Christians regard worship as something that they don’t only do for God, but that God, through Jesus’s example and the presence of the Holy Spirit is also at work in.

Church services (which is more than a building) has various agenda’s. Types of service will include hymns, readings and prayers and sometime partaking of the Lord’s Supper. The preacher will speak at length to expound a biblical text and bring out its relevance to those present. Different churches, even within the same denomination, will use very different styles of worship. Some will be elaborate, with a choir singing difficult music, others will hand the music over to the congregation, who sing simpler hymns or worship songs.
