The Christ's Assembly Worldwide, The Christ's Assembly or TCAWW for short, is an alliance of traditional Bible believing Christian ministries.
It describes itself as a descendant of the historical Celtic Orthodox Church that upholds the original Sabbath, the feasts and dietary laws while utilizing a canonical version of the English Liturgy (1549 book of common prayer). The church is led by duly consecrated Bishops in Apostolic Succession of the Celtic church lines from the American Orthodox Catholic Church.
