Summary

The work is a decretal letter attributed to Pope Caius (283–296) that addresses a single decree concerning the attribution of a person named Gaius. It survives only in later canonical collections, not in the original papal register, and its authenticity is uncertain. The text is transmitted through compilations such as the Pseudo-Isidorian decretals, which often interpolated or altered early papal letters. The historical Caius reigned during the Diocletianic persecution, but this decretal likely dates from the Carolingian period. This edition provides the Latin text and an English draft but lacks a critical apparatus or stemma codicum, preventing assessment of variant readings or manuscript relationships.

The work illustrates the Carolingian practice of retrojecting later ecclesiastical norms onto early popes, shaping medieval canon law and papal authority. It relates to the Pseudo-Isidorian decretals, a key source for medieval church governance, and to debates about the historicity of early papal decrees. Its content on clerical grades connects to patristic sources like Cyprian, showing how later compilers used earlier texts to validate their claims.

Historical context

The work is attributed to Pope Caius, who served as bishop of Rome from 283 to 296, a period of relative peace before the Diocletianic persecution (303–311). No genuine letters of Caius survive; the decretal is known only through later canonical collections, particularly the Pseudo-Isidorian decretals, a 9th-century Carolingian forgery that compiled and often fabricated papal decrees to support episcopal authority. The text likely originated in the Carolingian period (8th–9th centuries) in Francia, where such collections were produced to bolster papal and ecclesiastical power. The genre is canon law, specifically a decretal letter, a form that became common in the 4th–5th centuries but was anachronistically applied to earlier popes. The work's transmission is entirely through medieval manuscripts of canonical collections, with no contemporary evidence for its authenticity. Its content—a single decree on the attribution of a person named Gaius—may reflect later concerns about clerical order or authority, as suggested by parallels with Cyprian's letters and the Liber Pontificalis.

DE DECRETO UNICO QUOD CAIO ADSCRIBITUR, CIRCA ORDINANDOS. Papæ hujus non modo nulla ad nos transmissa est sincera epistola, sed nec ulla usquam memoratur. Tantum in pontificali lihro dicitur constituisse; ut omnes ordines in Ecclesia sic ascenderent: Si quis episcopus fleri mereretur, ut esset ostiariis, lector, cxorcista, acolythus, sequens subdiaconus, diaconus, presbyter, et exinde episcopus ordinaretur. » Quo decreto si constituisse intelligatur decere, ut quisque per ecclesiastica illa officia, non præcipiti saltu, ad episcopatum adscendat; jam hoc ante Caii tempora usu receptum fuisse fidem facit Cyprianus, cum Cornelii ordinationem legitimam fuissc inde probat (Cornel., ep. 10, n. 7), quod non iste ad episcopatum subito pervenisset, sed per omnia ecclesiastica officia promotus, et in divinis administrationibus Deum sæpe promeritus, ad sacerdotii sublime fastigium cunctis religionis gradibus adscendit. » Qui autem sint illi gradus, ipse nos docet Cornelius, cum in ecclesia sua tunc extitisse memorat (Ep. 9, n. 4) prcsbyteros 46, diaconos 7, subdiaconos totidem, acolythos 42, exorcistas et lectores cum ostiariis 52. » Cornelium tamen omnium illorum graduum officiis, nullo excepto, functum esse, non ausim affirmare.
English
CONCERNING THE SINGLE DECREE ATTRIBUTED TO CAIUS, REGARDING THOSE TO BE ORDAINED. Of this Pope, not only has no genuine letter been transmitted to us, but none is anywhere recorded. Only in the Pontifical Book is it said that he decreed: that all orders in the Church should be ascended thus: If anyone were to merit becoming a bishop, he should be ordained as porter, lector, exorcist, acolyte, then subdeacon, deacon, presbyter, and thereafter bishop. If by this decree he is understood to have established that each person should ascend to the episcopate through those ecclesiastical offices, not by a precipitate leap, Cyprian bears witness that this was already customary before the time of Caius, when he proves that the ordination of Cornelius was legitimate (Cornel., ep. 10, n. 7) because he did not arrive at the episcopate suddenly, but "promoted through all ecclesiastical offices, and having often merited God in divine administrations, he ascended to the sublime pinnacle of the priesthood through all the grades of religion." Moreover, what those grades are, Cornelius himself teaches us, when he records that in his church there then existed (Ep. 9, n. 4) "46 presbyters, 7 deacons, the same number of subdeacons, 42 acolytes, 52 exorcists and lectors together with porters." Yet I would not dare to affirm that Cornelius had served in the offices of all those grades, without exception.

Si vero supcrins constitutum vcluti lex censcatur ecclesiastica, a qua ncmo, nisi per cum qui legem tulit, immunis fiat, illud Caio longe recentius esse pluribus exemplis facile demonstratur. I osterius est hoc papa concilium Sardicense, utpote anno 347, habitum, cujus canone (Isidoro Mercatori 13), sancintur, ut si quis ex foro sive dives, sive scholasticus, episcopus fieri dignus habeatur, non prius constituatur, quam lectoris et diaconi et presbyteri ministerium peregerit; » vultque habeat uniuscujusque ordinis gradus non minimi temporis longitudinem, per quod et fides et morum probitas... possit cognosci. Tribus illis gradibus subdiaconatum adjiciunt Græci, qui tantum hos quatuor ordinum gradus cum episcopata agnoscunt, ut ex variis monimentis liquet, ac nominatim ex his synodi Octavæ, act. 10, cap.: Si quis.. per omnes gradus ecclesiasticos definitis temporibus vitam inculpatam transisse reperiatur, ita ut in lecturis munere unum, in suhdiaconi duos, in diaconi tres, in sacerdotii quatuor annos expleverit, ad episcopatus honorem evehatur. » Nunc igitur restat, ut etiam in latina Ecclesia, ac nominatim Romana, ab omnibus exactum non esse probemus, ut septem praedictos gradus prius obcant, quam ad episcopatum valeant efferri.
English
But if the aforementioned statute is regarded as an ecclesiastical law, from which no one is exempt except by the one who enacted the law, it is easily demonstrated by several examples that this decree is far more recent than Caius. Later than this pope is the Council of Sardica, held in the year 347, whose canon (Isidore Mercator 13) decrees that if anyone from the forum, whether rich or a scholar, is deemed worthy to become a bishop, he shall not be appointed before he has completed the ministry of lector, deacon, and presbyter; and it requires that he have a not insignificant length of time in each order's grade, through which both his faith and the probity of his morals... can be known. To those three grades the Greeks add the subdiaconate, who recognize only these four grades of orders together with the episcopate, as is evident from various monuments, and specifically from the acts of the Eighth Synod, act 10, chapter: "If anyone... is found to have passed through all ecclesiastical grades with blameless life for defined periods, so that he has completed one year in the office of lector, two in that of subdeacon, three in that of deacon, and four in that of priest, he shall be raised to the honor of the episcopate." Now it remains for us to prove that even in the Latin Church, and specifically the Roman, it was not required of all that they first pass through the seven aforementioned grades before they could be elevated to the episcopate.

Siricius epist. 1, ad Himerium, n. et 10, necnon Zosimus epist. 9, ad Hesychium, n. et 5, quibus quisque gradibus ad episcopi aut presbyteridignitatem provehendus esset definientes, non in ostiarii, sed in lectorum primitus gradu, » ut verbis utamur Zosimi, divini rudimenta servitii » poni præcipiunt. Immo duin Siricius de eo, qui grandævus baptizatur, constituit, ut si ad sacram militiam pervenire festinat, statim (a suscepto baptismo) lectorum aut exorcistarum numero societur, » non ab eo utrumque gradum, sed alterutrum tantum videtur exigcre. Cui concinens Zosimus de eodem decernit, « ut post baptismum statim, si divinæ militiæ desiderat mancipari, sive inter lectores sive inter exorcistas tencatur. » Quamquam iste Zosimi locus explicari, sic potest, ut perinde ipsi sit sive inter lectores, sive inter exorcislas, » atque I tum inter lectores tum, etc., » maxime cum his præmittat: Assuescat in Domini castris, in lectorum primitus divini rudimenta servitii; nec illi vile sit exorcistam, acolythum, subdiaconum, diaconum per ordinem fieri. » Illud mirum, quod cum Siricius et Zosimus in laudatis epistolis singulos tam accurate describant gradus, quibus ad sacerdotii apicem perveniri velint, ostiarium tamen constanter taceant. Hunc sane non præteriissent silentio, si a Caio decrelum superius prodiisset.
English
Siricius, in his first letter to Himerius, nos. 10 and 5, and likewise Zosimus, in his ninth letter to Hesychius, nos. 5 and 5, defining by which grades each person should be advanced to the dignity of bishop or priest, prescribe that one be placed not in the grade of doorkeeper, but first in that of lector, "to use the words of Zosimus, the beginnings of divine service." Indeed, when Siricius decrees concerning one who is baptized at an advanced age, that if he hastens to enter sacred military service, he should immediately (after receiving baptism) "be joined to the number of lectors or exorcists," he seems to require not both grades from him, but only one or the other. Zosimus, concurring with him, decrees concerning the same matter, "that after baptism, if he desires to be enlisted in divine military service, he should be held either among the lectors or among the exorcists." Although this passage of Zosimus can be explained in such a way that "either among the lectors or among the exorcists" is equivalent to "both among the lectors and among the exorcists," especially since he prefaces this with: "Let him become accustomed in the Lord's camp, first in the grade of lector, to the beginnings of divine service; and let it not be beneath him to become an exorcist, acolyte, subdeacon, deacon in order." It is remarkable that although Siricius and Zosimus, in the aforementioned letters, so accurately describe each of the grades by which they wish one to arrive at the summit of the priesthood, they nevertheless consistently remain silent about the doorkeeper. They would certainly not have passed over this in silence if the decree concerning Gaius had been issued earlier.

Cum ipsis ea in re consentit supposititium quidem, sed tamen antiquum Silvestri Constitutum, seu Romanum II, sub Silvestro concilium, cujus capite ii, statutum est: I Ut nullus ex laica per-. sona ad honorem acolythus a usque ad episcopatum sublevaretur, nisi prius fuisset lector annis xxx, deinde una die exorcista, et postea caperet onus acolythi, et faceret in eodem ordine acolythi annos de cem, ut acciperet onus subdiaconi, et in subdiaconatu esset annos quinque, etc. » Ut hic nullum praeterea de ostiario fit verbum, ita nec in iis ejusdem Constituti, cap.: Ut a subdiacono usque ad lectorem omnes subdili essent diacono cardinali urbis Romæ, in Ecclesia honorem repraesentans tantum, pontifici vero presbyteri, subdiaconi, diaconi, acolythi, exorcistae, lector in omni loco repræpsentans. obseQuium. » Idem tamen constitutum seu concilium cap. i, ostiarii meminit, ubi legimus: Ut non presbyter adversus episconum, non diaconus adveriUS presbyterum, non subdiaconis adversus diaconum, non exorcista adversus subdiaconum, non lector adversus exorcistam, non ostiarius adversus lectorem det accusationem aliquam. » Quapropter ex Siricii Zosimive silentio minime inferendum est ipsis ignotum fuisse ostiarii gradum, quem, ut dixi mus, Gornelius agnoviL.
English
In this matter, the spurious yet nonetheless ancient Constitutum Silvestri, or the Roman Council II under Silvester, agrees with them, in whose second chapter it is established: "I. That no lay person should be raised to the honor of acolyte up to the episcopate, unless he had first been a lector for thirty years, then an exorcist for one day, and afterwards take up the burden of acolyte, and remain in that same order of acolyte for ten years, so that he might take up the burden of subdeacon, and be in the subdiaconate for five years, etc." Just as here no mention is made of the doorkeeper, so also in those same chapters of the Constitutum: "That from subdeacon down to lector, all should be subject to the cardinal deacon of the city of Rome, representing honor only in the Church, but to the pontiff, the presbyters, subdeacons, deacons, acolytes, exorcists, and lector representing obedience in every place." Yet the same Constitutum or council, in chapter 1, mentions the doorkeeper, where we read: "That a presbyter should not bring any accusation against a bishop, nor a deacon against a presbyter, nor a subdeacon against a deacon, nor an exorcist against a subdeacon, nor a lector against an exorcist, nor a doorkeeper against a lector." Therefore, from the silence of Siricius or Zosimus, it is by no means to be inferred that the grade of doorkeeper was unknown to them, which, as we have said, Cornelius acknowledged.

Inde tamen colligi potest illos ab cis,.lui clero nomen dabant, nequaquam necessario exigendum censuisse, ut ostiarii ministerio fungerentur. Certe infantes, quos sacræ militiæ adscribi volebant, cum brevi potuerint lectorem officio fungi, non tam cito fiebant validi et ad implenda ostiarii munia idonei. Eorum quippe crat ab Ecclesiæ aditu indignos repellere. Augustinus, lib. de Pastoribus, nunc Serm. 46, n. 31, describit, quo pacto apud Donatistas ostiarius, « stans vcl sedens ad ostium » basilicarum, eos interroget qui intrare velint, ac projiciat qui non sint ejusdem communionis. Cui muneri impares erant infantes. Longe post Siricii Zosimique tempora Gelasius epist. XI, c. 2, licet ostiarii gradum agnoscat, ibidem tamen praescribit: « Si quis etiam de religioso proposito et disciplinis monasterialibus eruditus ad clericale munus accedit... continuo lector vel notarius aut certe defensor effectus, post tres menses existat acolythus. maxime si huic ætas etiam suffragatur, sexto mense subdiaconi nomen accipiat; adeoque non modo ostiarii, sed et exorcistæ gradum præteriri permittit. Nil opus est hic exempla eorum profeire, qui aliquo prædictorum septem graduum, vel etiam pluribus prætermissis, episcopatum adepti sunt.
English
Nevertheless, it can be inferred from this that they judged it by no means necessary to require that those who were enrolling in the clergy should actually perform the office of doorkeeper. Certainly, infants, whom they wished to enroll in the sacred militia, could serve as lectors for a short time, but they could not so quickly become strong and fit to fulfill the duties of doorkeeper. For it was the doorkeepers' role to repel the unworthy from the entrance of the Church. Augustine, in his book *De Pastoribus*, now Sermon 46, n. 31, describes how among the Donatists the doorkeeper, "standing or sitting at the door" of the basilicas, would question those who wished to enter and would cast out those who were not of the same communion. Infants were unequal to this task. Long after the times of Siricius and Zosimus, Gelasius, in his Epistle XI, chapter 2, although he recognizes the grade of doorkeeper, nevertheless prescribes there: "If anyone, even from a religious profession and trained in monastic disciplines, comes to the clerical office... he immediately becomes a lector, or a notary, or certainly a defensor; after three months he becomes an acolyte, especially if his age also favors this; in the sixth month he receives the name of subdeacon." And thus he permits not only the grade of doorkeeper but also that of exorcist to be passed over. There is no need here to adduce examples of those who, with one or even several of the aforementioned seven grades omitted, attained the episcopate.

Quocirca decretum, de quo agimus, ad Caium nihilo magis videtur pertinere, quam pertineat ad Silvestrum istud, quod nomine concilii Romani III, sub hoc papa vulgatum est: « Si quis clericatum promereri desiderai, hoc justum est, ut sit ostiarius annum unum, lector annos viginti, exorcista annos decem, acolythus annos quinque, subdiaconus annos quinque, diaconus annos quinque, etsi ad honorem presbyterii accedat, et faciens in ordine annos sex... sic ab omni Ecclesia eligatur consecrandus episcopus. » COUSTANT.
English
Therefore, the decree in question seems no more to pertain to Gaius than that which was published under the name of the Third Roman Council under this pope pertains to Sylvester: "If anyone desires to merit the clerical state, it is just that he be a doorkeeper for one year, a lector for twenty years, an exorcist for ten years, an acolyte for five years, a subdeacon for five years, a deacon for five years, and if he proceeds to the honor of the presbyterate, and spends six years in that order... thus let him be chosen by the whole Church to be consecrated bishop." COUSTANT.
