Original: Throughout most of Christianity 's history , corporate Christian worship has been primarily liturgical , characterized by prayers and hymns , with texts rooted in , or closely related to , the Scripture , particularly the Psalter ; this form of sacramental and ceremonial worship is still practiced by the Roman Catholic , Eastern Orthodox , and Anglican churches , as well as some Protestant denominations such as Lutheranism and Methodism .
Simplified: In many Protestant traditions , however , Communion is celebrated rarely or not at all , and corporate worship is centered on a formal sermon , which may resemble a lecture .
