¹ This article grew out a paper I delivered at the American Society of Church History's Winter Meeting in January 2012 and was further nurtured as part of my dissertation, “Constructing Christian Community: The Sermons of Chromatius of Aquileia, 388–407” (PhD Diss., University of Florida, 2013). I wish to thank Andrea Sterk for all of her critiques and suggestions and the anonymous readers at Church History for their helpful comments.

³ I put the term “Arians” in quotes here to recognize the constructed nature of the term. No person or church referred to itself as Arian. Likewise, the term covers numerous groups that would have probably viewed and dealt with each other as heretical and out of communion. I will use the term here as Chromatius would have recognized it, accepting that this does not reflect any sort of historical reality. “Arian” will denote the groups of Christians that were excluded from Nicene Christianity based on their beliefs about the person of Jesus. It includes groups that are labeled as Arian, Eunomian, and Photinan, among others. I will not always put the term in quotation marks, but the reader should remember that it is a constructed label which reflects power dynamics of the time.

⁷ The Sources Chrétiennes translations were published first and can still be used for reference: Sermons, SC 154 and 164 (Paris: Les Editions du Cerf, 1969–1971)Google Scholar. In the CCSL, sermons 33 and 36 were altered to reflect new discoveries. In addition, a sermon 42 (On the Passion of St. Peter) was added, though the editors (and I) find the sermon to be likely spurious: Chromatii Aquileiensis Opera, ed. and trans. Étaix, R. and Lemarié, J., CCSL 9A (Turnholti: Brepols, 1974)Google Scholar. The CCSL supplement, published in 1977, added yet another dubious sermon. This one was a compilation sermon from an early medieval homilarium—a greatest hits of ancient preachers including Ambrose, Jerome and Chromatius: Spicilegium ad Chromatii Aquileiensis Opera, ed. and trans. Étaix, R. and Lemarié, J., CCSL vol. 9A Supplementum (Turnholti: Brepols, 1977)Google Scholar.

All of these changes are well summarized in: Lemarié, Joseph, “‘Chromatiana’ apport de nouveaux témoins manuscripts,” Revue Bénedictine 98 (1988): 258–271Google Scholar. A partial commentary on Matthew can also be traced to Chromatius, though I will not be focusing on it in this article. The commentary, written for a small audience, would not have been influential: Chromatii Aquileiensis Opera, 184–498; Spicilegium ad Chromatii Aquileiensis Opera, 624–636.

²³ Williams, Ambrose, 227–232. Ambrose mentions the existence of Gothic Arians in Milan, and says they dwell in wagons, launching a thousand theories about the “nomadic” Goths. Ambrose's letter confirms or creates this point depending on one's point of view: Ep. 20:12. On the topic of the Goths as Arians see: Liebeschuetz, J. H. W. G., Barbarians and Bishops: Army, Church, and State in the Age of Arcadius and Chrysostom (New York: Oxford University Press, 1990), 53Google Scholar; Wolfram, Herwig, History of the Goths, trans. Dunlap, Thomas (Berkeley: University of California Press, 1988), 75–85Google Scholar. The suggestion that all the Goths were Arian may well be a later “propaganda” point of the Byzantines that we have adopted. As a warning see: Amory, Patrick, People and Identiy in Ostrogothic Italy, 489–554 (New York: Cambridge University Press, 1997), 245–247Google Scholar.

²⁵ I do not mean to suggest that the Christians in Aquileia were uniform in belief or every aspect of practice. Rather, I use the term “formal” to denote the lack of any other Christian institutions that would have actively competed with Chromatius's church for adherents a lá the Donatist/Catholic divide in North Africa or the Arian/Nicene split in Milan prior to 388.

²⁷ This approach suggests that anti-Jewish rhetoric in sermons and written texts, which often specifically deals with unbelief in the divinity of Christ, should be understood not as anti-Jewish rhetoric but as reflecting the rivalry with other Christian factions like the Arians.

³³ Interestingly, Chromatius does not exhibit the same tendency in his rhetoric about Jews. He referred to Jews as members of the community and, while he attacked them for their denial of Christ's divinity, he did not descend into attacks on Jewish immorality or other common tropes. See: Thelamon, “Les Vaines,” 114.

⁴⁰ Rufinus probably took the story from Athanasius who propagated the story in a letter from 356. It does seem that the death of Arius is linked to the death of Judas in Acts 1:18.

⁴² Asad, Talal, “Medieval Heresy: An Anthropological View,” Social History 11, no. 3 (1986): 356Google Scholar. This article dealt with heresy in a later period that had different processes and institutions. Nonetheless, the act of labeling a heretic is still a power process, for it presumes the ability to deny legitimacy to the other person or group. Accusations of heresy might be thrown out by both sides, but a dominant, institutional power structure, which is denoted by its ability to enforce its will through law, denial of property or legitimacy, or any other means, is the only source for producing and maintaining a narrative of heresy and orthodoxy which eventually becomes a reality. The irony is that the construction of such a narrative reinforces the existence of the power structure, creating a vicious cycle of demonization.

⁴⁹ A full list would be too long here. For a few of the earliest examples of difference within the proto-church, I would suggest the debate in Acts 15 over the need for gentiles to adopt Mosaic law, the differences between Paul and Peter in Galatians 2, the issue of eating meat sacrificed to idols in Romans 14, and the railing against “false teachers” in Jude and 1 John.

⁵⁵ Sermon 41:7.

⁵⁶ Sermon 33:1. Chromatius's knowledge of Hebrew is obviously doubtful, though his close relationship with Jerome, who created and translated several commentaries on the Hebrew Bible for Chromatius and sent them to him over the years, raises the possibility that this was more than a bluff. Williams, Megan, The Monk and the Book Jerome and the Making of Christian Scholarship (Chicago: University of Chicago Press, 2006), 283, 286–290, and 297Google Scholar.

⁵⁷ Sermon 33:2.

⁵⁸ I previously discussed how Chromatius employs the labels of “heretic” and “Arian.” The labels of “Jew” and “Jewish” is also problematic. While persons would use the term(s) as self-identifiers the labels could also be a pejorative for Christians or pagans that attended the synagogue for services. I read the label as reflecting the presence of the Jewish community in Aquileia because of how Chromatius addresses Jews in one sermon (16:4), but it may also encompass persons that were not actually Jewish and merely attended the synagogue on occasion.

⁵⁹ Sermon 4:1. The scriptural quotation is Ecclesiastes 4:12. The interpretation seems adopted from Origen, In Exodum, IX:3. Noted in: Sermons, 2:161n1.

⁶⁰ Sermon 4:2.

⁶¹ Sermon 9:1. The scriptural quotation is Psalm 11:1.

⁶² Sermon 21:3.

⁶³ This version of a unified Christianity appears in Chromatius's sermons, but even more so in Rufinus's Ecclesiastical History. This work was closely tied to Chromatius as he commissioned it, paid for it, and was the dedicatee. For the links between Chromatius and the EH, see: Thelamon, Païens et chrétiens, 151–155.
