The Altar Guild serves God and the local parish by preparing and maintaining the altar and worship space for liturgical services. In the Anglican tradition, the Altar Guild's work is considered a ministry of hospitality and reverence, ensuring that the church is ready for worship in a way that glorifies God and helps the congregation enter into sacred space.

The Altar Guild prepares the worship space by setting up for the Eucharist, maintaining sacred vessels and linens, and adjusting paraments and vestments for the liturgical seasons. They ensure the altar remains clean and reverent while assisting clergy in preparing for services, offering their work as a quiet act of devotion.
