rhetorical education in Greek and Latin grammar; without which it was not possible for a boy raised with a knowledge only of Late Antique vernacular speech to express himself in approved classical linguistic forms. Priests and archpriests It was expected that the normal president at both the Eucharist and Baptism would be the bishop, who would celebrate in the cathedral and in titular churches in turn. However, in practice, the bishop needed deputies for the Eucharist and also for the Divine Office of daily prayer, and this duty fell to the priests. The bishop selected a senior priest as archpriest who acted as his official deputy in all ritual matters and as head of the familia. The archpriest was also responsible for the cathedral school. After the 5th century, there were no longer state-supported secular teachers of rhetoric and grammar in the West (other than in parts of Italy) and so the church would have to educate its own. Deacons, subdeacons and archdeacons Just as the presbyters deputised for the bishop in ritual matters, so the deacons deputised in administrative and financial matters, especially in the raising and delivering of charity. At the head of the diaconate was the archdeacon; the bishop's main deputy in managerial affairs. Originally inferior in rank to the archpriest, the archdeacon by the sixth century had established clear pre-eminence. Subdeacons assisted the deacons, but unlike them were allowed to marry after ordination; consequently many clerics stopped the cursus honorum at this point, and it was not unusual for a subdeacon to be elected bishop; and even Pope. Doorkeepers, exorcists, lectors, acolytes and primicerius In practice, the first three of these orders tended to be given together, and were typically applied to boys as young as seven. These boy lectors were too young for the grammar school, but were valued as choristers, and so were included in the Schola Cantorum or choir school. Originally under the responsibility of the deacons, the organisation of choirs was reformed by Pope Gregory the Great, who introduced the office of primicerius or head cantor for this purpose. This proved a vital reform; as without any comprehensive system of musical notation, the only way that sacred music could be maintained and passed on was through professional choirs of sound musical training undertaking cathedral worship – and such skills are not guaranteed to be present in high-ranking ecclesiastics.
