In ecclesiastical law

The general assembly of the clergy to consult upon ecclesiastical matters. The clergy were always summoned at the commencement of each parliament. They themselves constituted a parliament, with a higher and lower house of convocation; the higher including the bishops and archbishops; the lower, the rest of, the clergy. It is still summoned before each parliament pro forma, preserving the ancient custom, but adjourns without transacting any business.
