_Marinian_. Yet this Church revolted sometimes from the Church of _Rome_,
but returned again to its obedience.

The rest of _Italy_, with the Islands adjacent, containing the
_suburbicarian_ regions, or ten Provinces under the temporal Vicar of
_Rome, viz._ 1_Campania_, 2_Tuscia_ and _Umbria_, 3_Picenum suburbicarium_,
4_Sicily_, 5_Apulia_ and _Calabria_, 6_Brutii_ and _Lucania_, 7_Samnium_,
8_Sardinia_, 9_Corsica_, and 10_Valeria_, constituted the proper Province
of the Bishop of _Rome_. For the Council of _Nice_ in their fifth Canon
ordained that Councils should be held every spring and autumn in every
Province; and according to this Canon, the Bishops of this Province met at
_Rome_ every half year. In this sense Pope _Leo_ I. applied this Canon to
_Rome_, in a decretal Epistle to the Bishops of _Sicily_, written _Alippio
& Ardabure Coss_. A.C. 447. _Quia saluberrime_, saith he, _a sanctis
patribus constitutum est, binos in annis singulis Episcoporum debere esse
conventus, terni semper ex vobis ad diem tertium Kalendarum Octobrium Romam
aeterno concilio sociandi occurrant. Et indissimulanter a vobis haec
consuetudo servetur, quoniam adjuvante Dei gratia, facilius poterit
provideri, ut in Ecclesiis Christi nulla scandala, nulli nascantur errores;
cum coram Apostolo Petro semper in communione tractatum fuerit, ut omnia
Canonum Decreta apud omnes Domini sacerdotes inviolata permaneant_. The
Province of _Rome_ therefore comprehended _Sicily_, with so much of _Italy_
and the neighbouring Islands as sent Bishops to the annual Councils of
_Rome_; but extended not into the Provinces of _Ravenna_, _Aquileia_,
_Millain_, _Arles_, &c. those Provinces having Councils of their own. The
Bishops in every Province of the _Roman_ Empire were convened in Council by
the Metropolitan or Bishop of the head city of the Province, and this
Bishop presided in that Council: but the Bishop of _Rome_ did not only
preside in his own Council of the Bishops of the _suburbicarian_ regions,
but also gave Orders to the Metropolitans of all the other Provinces in the
_Western Empire_, as their universal governor; as may be further perceived
by the following instances.

Pope _Zosimus_ A.C. 417, cited _Proculus_ Bishop of _Marseilles_ to appear
before a Council at _Rome_ for illegitimate Ordinations; and condemned him,
as he mentions in several of his Epistles. Pope _Boniface_ I. A.C. 419,
upon a complaint of the Clergy of _Valentia_ against _Maximus_ a
