Down to the fifth century, the administration of the sacraments and the celebration of the holy communion took place in the cathedral only. Pope St. Marcellus founded, in the fourth century, twenty-five _titles_ or parishes in Rome, in order to afford greater facilities for the preparatory instruction by which the sacraments of baptism and penance were preceded. But in the fifth century, when the cathedrals were found too small to hold all the congregation, it became the custom to distribute, in the _titles_ or parishes of the city, the holy eucharist which the bishop sent by the hands of deacons to the titulary clergy. The bishops also delegated to their clergy the power of receiving the reconciliation of the penitents in cases of necessity, of admitting heretics in danger of death (but only in the bishop’s absence), and of pronouncing excommunications in their parishes, by virtue of a sentence delivered by the bishop. The clergyman also visited the sick, administered the sacrament of extreme unction, blessed the private dwelling-places, and himself selected the staff for his church. At last, in the sixth century, clergymen celebrated, in the quarters or _titles_ wherein they ministered, the entire liturgy of the holy communion, and from the seventh century they were empowered to diminish or to increase, as they thought proper, in accordance with the revenues of the parish, the number of the clerks, choristers, and the various subordinate officers. In compliance with the wishes of the faithful, the bishop would often authorise the clergy to celebrate two masses upon the same day, one to take place of necessity in the parish church, the other perhaps in some oratory attached to the parish (Fig. 223).
