A Carolingian view of clerical marriage
When did priests stop being allowed to marry in medieval western Europe? The question might seem recondite, but it’s actually of enormous importance.
The prohibition of clerical marriage separated out priests from the laity in a very clear and obvious way, in parallel to their exemption from processes of secular justice (one of the focuses of my research at the moment). It meant that they couldn’t legally have heirs, which had a big impact on wider family strategies; and it was associated with changes in masculinity, too.
Establishing when this happened is however surprisingly difficult. The key texts are often ambiguous. And of course, for the early Middle Ages we don’t have enough evidence to be able to say for certain exactly what proportion of priests were married (though recent research on local priests by Julia Barrow and a team led by Steffen Patzold and Carine van Rhijn has moved things on here a lot).
Nevertheless, many historians would suggest that the history goes something like this. Early church councils were keen for clerics in general (and bishops in particular) to refrain from illicit sexual activity, and ideally from all sexual activity. But as good householders, it was expected that these leaders would be married men: They merely had to be continent after their ordination. That tradition was maintained for centuries – the classic illustration is that Pope Hadrian II (d. 872) was a married man, and no one at the time batted an eyelid. Only in the eleventh century did reformers, seeking to create an autonomous church free from secular control, develop a novel insistence on clerical celibacy (as opposed to merely clerical continence within marriage), leading to a formal legal prohibition in the 12th century.
In many ways this is a convincing and accurate narrative. Yet there are two problems. The first is that the narrative perhaps doesn’t take sufficiently into account regional diversity in the early Middle Ages. Ninth-century Italian clerics, in particular, seem to have treated clerical careers very differently from their Frankish colleagues, as Rachel Stone has shown – so we can’t necessarily generalise from the case of Pope Hadrian.
Perhaps an even bigger problem though is that we tend to approach the late antique councils directly, relying on the most recent editions and the sharpest-sighted interpretations to work out what the church fathers originally had in mind. That’s obviously a good thing. But it’s not necessarily how early medieval authors read them.
Here’s a case in point (brought to my attention by Helen Parish’s excellent book). In the late 860s, Pope Nicholas I and Photius the Patriarch of Constantinople became caught up in a fierce argument. It ultimately revolved around about the extent of papal authority, but as part of this argument, a Byzantine letter began to circulate that criticised western church customs. When he heard about this, Pope Nicholas called for Frankish backup. Of the several treatises that were written in response, perhaps the most interesting for our purposes is that written by Ratramnus of Corbie in 867, known as the Contra Graecorum opposita.
Ratramnus was a noted Carolingian intellectual who remains understudied, overshadowed by his (much less sympathetic) fellow monk Radbert. This work of his is no exception, and it languishes in an inadequate 18th-century edition to this day. Yet it’s of considerable interest for the relatively level-headed defence of western customs that occupies most of its fourth book (and Ratramnus’s emphasis on the western/eastern (orientalis/occidentialis) distinction is incidentally quite striking).
Ratramnus argues for instance that whether clerics shaved their beards (as the Romans did) or whether they didn’t (like the Byzantines) was just a matter of local custom, not of doctrine. There was a ritual logic to doing things the way people did in the western churches, but he didn’t think the Byzantines should necessarily follow suit. In the end it wasn’t that important.
On clerical marriage, however, Ratramnus was more intransigeant. He had heard that the Byzantines labelled the Roman church as anti-marriage because they would not let their priests marry. Nonsense, said Ratramnus – the Apostle Paul wasn’t married, yet that hadn’t stopped him telling people that they ought to marry.
But, argued Ratramnus, it was simply inappropriate for priests to marry, since they would inevitably become distracted by trying to please their wives rather than God (an indication perhaps of a typically Carolingian companionate view of marriage). And there was also the problem of ritual pollution, though Ratramnus seems much less bothered by this, consistent with his other work.
Not content with leaving matters there, Ratramnus declared that this was in fact the traditional position, and he cited the Council of Nicaea of 325 to prove his point. Now, modern scholars are unanimous that the Council of Nicaea did not ban clerics from being married. But that’s not how Ratramnus seems to interpret the key canon, canon 4. This canon forbade priests from cohabiting with women except for close family members. It doesn’t mention wives – but in a fascinating short passage (translated below), Ratramnus uses common sense to argue that this was implied.
Was Ratramnus arguing that priests once ordained should not marry, or that they should be actually not be married at all? Here there’s a touch of perhaps deliberate ambiguity to the Latin. He says that priests shouldn’t matrimonia sortiri (lit: ‘acquire marriages’) which implies a prohibition on becoming married after ordination. But he also says that uxoria copula (lit: ‘wifely bond/union’) is forbidden to priests. Now, this could in principle mean sexual contact with one’s wife – but the context, and the other occasions on which Ratramnus uses this phrase, strongly suggest he meant the state of being married. 
In arguing that the Nicene Fathers prohibited priests from being married, Ratramnus was almost certainly misrepresenting the Nicene council’s original intentions. But in a sense, that’s irrelevant. What matters is that for this ninth-century author, clerical celibacy was baked into the early church decisions – and moreover that this was a key factor in separating the laity from the priests.
Historians working on clerical celibacy and other related issues naturally tend to focus on new and dramatic texts produced in the eleventh century. But to what extent had the groundwork for these new texts already been laid by subtle, and much harder to discern, changes in how pre-existing texts were interpreted?

But let us come to the ecclesiastical decrees, by which we may understand what they [the maiores] wished to decide about this. In the Council of Nicaea held under Emperor Constantine I, it was thus decided by 380 bishops: “The great synod stringently decreed that it was not permissible for a bishop, priest or deacon, or absolutely anyone else in the clergy, to have a woman living in (mulier subintroducta): Except perhaps his mother, or sister, or aunt, or those women who escape suspicion”.
Let these Constantinopolitan emperors hear this, and judge whether those grades this canon concerns ought to obtain marriage (matrimonia sortiri) – grades to whom it is not permitted to cohabit with women, except only those persons whom no suspicion can stain. For whoever marries (duxerit) a wife is unable not to have other women in the household too apart from his wife, women through whom wifely necessity and domestic business (domestica cura) may be supplemented. In truth where the living-in (subintroductio) of all women is forbidden, except for those persons who lack all suspicion, it is clear that a wifely union (uxoria copula) is also forbidden, since this can in no way happen without contact (accessio) with other women.
 Earlier in the passage, R. wrote that Paul “significat se caelibem esse, nec uxoris copula detineri” – ie, that he was not married. Cf. his comment re: the 862 council of Aachen here: “quod autem opponitur non fuisse copulam illam legitimum conubium”
 nec inter laicos et sacri altaris ministros ullam differentiam consistere.
 Sed veniamus ad ecclesiastica tandem decreta, quo cognoscamus quid decernere super his maluerint. In Nicaeno concilio sub Constantino imperatore primo per trecentos octodecim episcopos sic decernitur: «Interdixit per omnia magna synodus, non episcopo, non presbytero, non diacono, nec alicui omnino qui in clero est, licere subintroductam habere mulierem; nisi forte matrem, aut sororem, aut amitam, vel eas tantum personas quae suspiciones effugiunt.» Audiant haec Constantinopoleos imperatores, et judicent, an debeant isti gradus, super quibus hoc capitulo decernitur, matrimonia sortiri, quibus non licet mulieribus cohabitare, nisi solummodo personis illis quas nulla suspicio possit commaculare. Nam quisquis uxorem duxerit, non potest praeter uxorem alias etiam mulieres in domo non habere, quibus uxoria necessitas, et cura domestica suppleatur. Ubi vero cunctarum interdicitur subintroductio feminarum, praeter omnino personas quae careant omni suspicione, manifestum est quod interdicatur etiam uxoria pariter copula, quae nullo modo potest fieri sine reliquarum accessione feminarum.
