 Movable altars include the free-standing wooden tables without altar stone, placed in the choir away from the east wall, favoured by churches in the Reformed tradition.Altars that not only can be moved but are repeatedly moved are found in low church traditions that do not focus worship on the Eucharist, celebrating it rarely.Both Catholics and Protestants celebrate the Eucharist at such altars outside of churches and chapels, as outdoors or in an auditorium.
