Some liturgists maintain that the early Church in its processions followed Old Testament precedents, quoting such cases as the procession of the ark round the walls of Jericho, the procession of David with the ark, the processions of thanksgiving on the return from captivity, &c. The liturgy of the early Church as Duchesne shows was influenced by that of the Jewish synagogue, but the theory that the Church's processions were directly related to the Old Testament ritual is of later origin.
