The Aquileian Rite was a particular liturgical tradition within the province of the ancient patriarchal see of Aquileia.
The See of Aquileia under Bishop Macedonius broke communion with Rome in the Schism of the Three Chapters in 553 and became a schismatical patriarchate, a situation which lasted till the year 698. A number of allusions tell us that Aquileia and certain of its suffragan sees had a special rite (generally called the ritus patriarchinus "patriarchate rite"); but they do not give us any clear indication as to what this rite was.
The earliest and most instructive document of the Patriarchine Rite is a capitulare of the eighth century added by a Lombard hand to the "Codex Richdigeranus" of the sixth century. Germain Morin and H. F. Haase, who edited the Codex, show reason to suppose that this capitulare represents the use of Aquileia.
Supposing this, it gives us valuable information about the Aquileian liturgical Calendar for the time it covers (Advent to June). Advent had five Sundays; St. Stephen's Day is 27 December, as in the Rites of Jerusalem-Antioch and their descendants. There is no Septuagesima; two Sundays (Sexagesima and Quinquagesima) prepare for Lent. The "tradition of the symbol" is on the Sunday before Easter. It and Maundy Thursday have each two Masses, as in the Gallican Rites. There is a "Mid- Pentecost" feast, as in many Eastern Rites. We have then many indications of the divergence from Rome; this fragment of a calendar points to Gallican usages mixed with some from the East. If we accept the most probable theory that the Gallican Rite is Eastern (Antiochene) in origin, we may consider the local Aquileian Use as one more variant of the widespread Gallican family. For the rest we are reduced to mere conjecture about this liturgy.
There are many theories, especially as to its relation to the rites of Milan, Ravenna, and the fragments in St. Ambrose of Milan's De sacramentis, IV, 4-6. Dr. Buchwald defends the view that the prayers in "De Sacr." are Aquileian. Aquileia adopted them from Alexandria, under whose influence she stood (according to the synod of Aquileia of 381; op. cit., 47). Rome then took her Canon from Aquileia about the fifth century. If this be true, the influence of Aquileia on the Western liturgy has been enormous. Aquileia would be the portal by which the Roman Canon came to Europe. Baumstark ascribes De sacramentis to Ravenna rather than to Milan, but agrees that it came originally from Alexandria, Egypt and that Aquileia used the same rite. The ritus patriarchinus then would be the same as the Rite of the Exarchate of Ravenna, which he defends From the time of the formation of separate rites in the fourth century, Aquileia would have certainly had its own use. This use was not the same as that of Rome, but was probably one more variant of the large group of Western Rites, connected by (Eastern?) origin, which we call Gallican. It was probably really related to the old Milanese Rite and perhaps still more to that of Ravenna.
In the later Middle Ages we hear of the ritus patriarchinus yielding steadily to the Roman Rite. Ebner has published a variant of the present Hanc igitur of the Roman Canon, in litany form, attributed to Paulinus of Aquileia (787-802). De Rubeis in his De sacris foroiuliensium ritibus has printed part of the Aquileian scrutiny of catechumens, of the ninth century. This is practically that of the contemporary Roman Ordines; so the Roman Rite was already replacing the other one. Walafrid Strabo (later ninth century) mentions "hymns" composed by Paulinus of Aquileia and used by him "in private Masses at the offering of the sacrifice."
It seems that the Rite of Aquileia had even been used in Venice since in 1250 Peter IV, Bishop of Castello petitioned the Pope for permission to adopt the Roman Rite. In 1308 and again in 1418 attempts were made to restore the Aquileian Use at Venice. But in 1456 Pope Callistus III granted permission to the newly created Patriarch of Venice to follow Roman liturgical practice.
After the Council of Trent and Pope Pius V's Missal (1570) one after another of the cities which had kept the Aquileian Use conformed to Rome: Trieste in 1586, Udine in 1596. Como alone made an effort to keep the old local use. In 1565 and 1579 diocesan synods still insisted on this. But in 1597 Clement VIII insisted on Roman Use here too. Only St Mark's Basilica, still the chapel of the Doge and not yet cathedral of Venice, kept certain local peculiarities of ritual which apparently descended from the "ritus patriarchinus" until the fall of the Republic in 1807.
But long before its final disappearance, the Aquileian Rite in these local forms was already so romanized that little of its original character was left. Francis Bonomio, Bishop of Vercelli, who went to Como in 1579 to persuade its clergy to adopt the Roman Breviary, says that the local rite was almost the same as that of Rome "except in the order of some Sundays, and the feast of the Holy Trinity, which is transferred to another time". So the Missale pro s. aquileyensis ecclesiae ritu, printed at Augsburg in 1494, breviaries and sacramentaries (rituals) printed for Aquileia, Venice and Como in the fifteenth century, although still bearing the name of the "ritus patriarchinus" (or "ritus patriarchalis"), are hardly more than local varieties of the Roman Rite .
