of _Arles_ in their Letter to Pope
_Leo_ I. _Cui id etiam honoris dignitatisque collatum est_, say they, _ut
non tantum has Provincias potestate propria gubernaret; verum etiam omnes
Gallias sibi Apostolicae Sedis vice mandatas, sub omni ecclesiastica regula
contineret_. And Pope _Pelagius_ I. A.C. 556, in his Epistle to _Sapaudus_
Bishop of _Arles_: _Majorum nostrorum, operante Dei misericordia, cupientes
inhaerere vestigiis & eorum actus divino examine in omnibus imitari:
Charitati tuae per universam Galliam, sanctae Sedis Apostolicae, cui divina
gratia praesidemus, vices injungimus_.

By the influence of the same imperial Edict, not only _Spain_ and _Gallia_,
but also _Illyricum_ became subject to the Pope. _Damasus_ made
_Ascholius_, or _Acholius_, Bishop of _Thessalonica_ the Metropolis of
_Oriental Illyricum_, his Vicar for hearing of causes; and in the year 382,
_Acholius_ being summoned by Pope _Damasus_, came to a Council at _Rome_.
Pope _Siricius_ the successor of _Damasus_, decreed that no Bishop should
be ordained in _Illyricum_ without the consent of _Anysius_ the successor
of _Acholius_. And the following Popes gave _Rufus_ the successor of
_Anysius_, a power of calling Provincial Councils: for in the Collections
of _Holstenius_ there is an account of a Council of _Rome_ convened under
Pope _Boniface_ II. in which were produced Letters of _Damasus_,
_Syricius_, _Innocent_ I. _Boniface_ I. and _Caelestine_ Bishops of _Rome_,
to _Ascholius_, _Anysius_ and _Rufus_, Bishops of _Thessalonica_: in which
Letters they commend to them the hearing of causes in _Illyricum_, granted
by the Lord and the holy Canons to the Apostolic See thro'out that
Province. And Pope _Siricius_ saith in his Epistle to _Anysius_: _Etiam
dudum, frater charissime, per Candidianum Episcopum, qui nos praecessit ad
Dominum, hujusmodi literas dederamus, ut nulla licentia esset, sine
consensu tuo in Illyrico Episcopos ordinare praesumere, quae utrum ad te
pervenerint scire non potui. Multa enim gesta sunt per contentionem ab
Episcopis in ordinationibus faciendis, quod tua melius caritas novit_. And
a little after: _Ad omnem enim hujusmodi audaciam comprimendam vigilare
debet instantia tua, Spiritu in te Sancto fervente: ut vel ipse, si potes,
vel quos judicaveris Episcopos idoneos, cum literis dirigas, dato consensu
qui possit, in ejus locum qui defunctus vel depositus fuerit, Catholicum
Episcopum vita & moribus probatum, secundum Nicaenae Syn
