One modification regarding the cardinals:
And of Evaristus (99-107?): "Hic titulos in urbe Româ dividit presbyteris et VII diaconos ordinavit qui custodirent episcopum prædicantem, propter stilum veritatis" (op. cit., I, 126), i.e., he divided among the
priests the "titles" of the city of
Rome, and
ordained seven
deacons to bear witness to the preaching of the
bishop
Then...
Fabian (236-250): "Hic regiones dividit diaconibus et fecit VII subdiaconos, qui VII notariis immiterent, ut gestas martyrum in integro fideliter colligerent, et multas fabricas per cymeteria fieri præcipit" (op. cit., I, 148), i.e., he divided the "regions" among the
deacons and created seven
subdeacons whom he placed over the notaries
Thereby:
These regionary
deacons were wont to subscribe the acts of Roman
synods and other documents as
diaconi ecclesiæ Romanæ, or
deacons of the
Roman Church, sometimes, probably, adding their proper region. Thereby also were expressed the fixity of their relations to the church of the
Bishop of Rome and their
obligation to assist him at
liturgical functions. It was natural enough, therefore, that the term
cardinales should very soon be applied to these regionary
deacons (
diaconi cardinals)
