Hierarchy of Order

The Council of Trent has defined the Divine institution of the first three grades of the hierarchy of order, i.e. the episcopate, priesthood, and diaconate (Sess. XXIII, De sacramento ordinis, cap. iv, can. vi). The other orders, i.e. those of subdeacon, acolyte, exorcist, lector, and porter, are of ecclesiastical institution. There is some controversy about the subdiaconate. The Council of Trent did not decide the question, but only declared that Fathers and councils place the subdiaconate among the major orders (loc. cit., cap. ii). It is now pretty generally held that the subdiaconate is of ecclesiastical institution, chiefly because of the lateness of its appearance in ecclesiastical discipline. Its introduction was due to the unwillingness of certain Churches to have more than seven deacons, conformably to Apostolic practice in the Church of Jerusalem (Acts 6:1-6). Furthermore, the ordination rite of subdeacons does not seem sacramental, since it contains neither the imposition of hands nor the words "Receive the Holy Ghost". Finally, in the Eastern Catholic Churches the subdiaconate is reckoned among the minor orders. For this opinion may be quoted Urban II in the Council of Benevento in 1091 (Hardouin "Acta Conc.", VI, ii, 1696, Paris, 1714), the "Decretum" of Gratian (pars I, dist. xxi, init.), Peter Lombard ("Sent.", Lib. IV, dist. xxiv), and others; see Benedict XIV, "De Synodo Di cesanâ.", VIII, ix, n. 10). This hierarchy of ecclesiastical origin arose at the end of the second and the beginning of the third century, and appears definitely fixed at Rome under Pope Cornelius (251-252), who tells us that in his day the Roman Church counted 46 priests, 7 deacons, 7 subdeacons, 42 acolytes, and 52 clerics of lower grades, exorcists, lectors, and porters (Eusebius, "Hist. Eccl.", VI, 43). In the primitive Church there were also deaconesses, widows, and virgins, but these did not belong to the hierarchy properly so called, nor does Pope Cornelius include them in his list of the Roman clergy. Their principal functions were prayer, the practice of works of charity, and of hospitality; while they performed certain liturgical functions, as in the baptism of women and at the agape, they never took any part, except by unauthorized abuse, in the ministry of the altar strictly speaking (Duchesne, "Christian Worship", London, 1904). Finally, although abbots of monasteries may confer the four minor orders, they do not constitute a special order or grade in the hierarchy. It is not by virtue of the blessing they receive from the bishop that they may confer orders, but by virtue of a privilege which canon law grants to abbots who have received such solemn blessing from a bishop (Gasparri, "Tractatus Canonicus de sacrâ ordinatione", I, iv, Paris, 1893). The Latin Church, therefore, counts eight grades in the hierarchy of order, the episcopate being counted a separate order from that of the priesthood, and ecclesiastical tonsure not being an order.
