Nunc fraternitatis tuae animum ad servandos canones, & tenenda decretaliae constituta, magis ac magis incitamus: ad haec quae ad tua consulta rescripsimus in omnium Coepiscoporum perferri facias notionem; & non solum eorum, qui in tua sunt dioecesi constituti, sed etiam ad universos Carthaginenses ac Boeticos, Lusitanos atque Gallicos, vel eos qui vicinis tibi collimitant hinc inde Provinciis, haec quae a nobis sunt salubri ordinatione disposita, sub literarum tuarum prosecutione mittantur. Et quanquam statuta sedis Apostolicae vel Canonum venerabilia definita, nulli Sacerdotum Domini ignorare sit liberum: utilius tamen, atque pro antiquitate sacerdotii tui, dilectioni tuae esse admodum poterit gloriosum, si ea quae ad te speciali nomine generaliter scripta sunt, per unanimitatis tuae sollicitudinem in universorum fratrum nostrorum notitiam perferantur; quatenus & quae a nobis non inconsulte sed provide sub nimia cautela & deliberatione sunt salubriter constituta, intemerata permaneant, & omnibus in posterum excusationibus aditus, qui jam nulli apud nos patere poterit, obstruatur. Dat. 3 Id. Febr. Arcadio & Bautone viris clarissimis Consulibus, A.C. 385. Pope Liberius in the reign of Jovian or Valentinian I. sent general Decrees to the Provinces, ordering that the Arians should not be rebaptized: and this he did in favor of the Council of Alexandria, that nothing more should be required of them than to renounce their opinions. Pope Damasus is said to have decreed in a Roman Council, that Tithes and Tenths should be paid upon pain of Anathema; and that Glory be to the Father, &c. should be said or sung at the end of the Psalms.

But the first decretal Epistle now extant is this of Siricius to Himerius; by which the Pope made Himerius his Vicar over all Spain for promulging his Decrees, and seeing them observed. The Bishop of Sevill was also the Pope’s Vicar sometimes; for Simplicius wrote thus to Zeno Bishop of that place: Talibus idcirco gloriantes indiciis, congruum duximus vicaria Sedis nostrae te auctoritate fulciri: cujus vigore munitus, Apostolicae institutionis Decreta, vel sanctorum terminos Patrum, nullatenus transcendi permittas. And Pope Hormisda made the Bishop of Sevill his Vicar over Boetica and Lusitania, and the Bishop of Tarraco his Vicar over all the rest of Spain, as appears by his Epistles to them.

Pope Innocent the first, in his decretal Epistle to Victricius Bishop of Rouen in France, A.C. 404, in pursuance of the Edict of Gratian, made this Decree: Si quae autem causae vel contentiones inter Clericos tam superioris ordinis quam etiam inferioris fuerint exortae; ut secundum Synodum Nicenam congregatis ejusdem Provinciae Episcopis jurgium terminetur: nec alicui liceat, Romanae Ecclesiae, cujus in omnibus causis debet reverentia custodiri, relictis his sacerdotibus, qui in eadem Provincia Dei Ecclesiam nutu Divino gubernant, ad alias convolare Provincias. Quod siquis forte praesumpserit; & ab officio Clericatus summotus, & injuriarum reus judicetur. Si autem majores causae in medium fuerint devolutae, ad Sedem Apostolicam sicut Synodus statuit, & beata consuetudo exigit, post judicium Episcopale referantur. By these Letters it seems to me that Gallia was now subject to the Pope, and had been so for some time, and that the Bishop of Rouen was then his vicar or one of them: for the Pope directs him to refer the greater causes to the See of Rome, according to custom. But the Bishop of Arles soon after became the Pope’s Vicar over all Gallia: for Pope Zosimus, A.C. 417, ordaining that none should have access to him without the credentials of his Vicars, conferred upon Patroclus the Bishop of Arles this authority over all Gallia, by the following Decree.
