Christians share many beliefs, but they don’t all agree on everything. This has resulted in the development of different groups within the religion called denominations. Examples of these include Anglican, Methodist, Baptist and Catholic.

Different Christian denominations worship in different ways. Anglicans, Catholics and Orthodox Christians have a set form of worship. It is a formal ritual based around the sacraments, particularly Holy Communion. This type of worship is called liturgical worship.

Other Christian churches, such as Baptists and Quakers, practice non-liturgical worship. This kind of worship has no set form and often does not involve Holy Communion. Non-liturgical worship is usually centered on Bible readings, a sermon, music and prayers.

As well as worshiping in different ways, Christian churches do not always look the same. For example, many Orthodox and Catholic Churches are more ornate and detailed, whereas Baptist or Methodist chapels are usually much simpler buildings.
