The Cassinese Benedictines, for instance, at first carefully differentiated between "conversi", "commissi" and "oblati"; the nature of the vows and the forms of the habits were in each case specifically distinct. The "conversus", the lay brother properly so called, made solemn vows like the choir monks, and wore the scapular; the "commissus" made simple vows, and was dressed like a monk, but without the scapular; the "oblatus" made a vow of obedience to the abbot, gave himself and his goods to the monastery, and wore a sober secular dress.
