In the 13th he speaks of a Writing he had made against Felix of Urgel, and of a Dialogue of that Author between a Christian and a Saracen.
The 29th directed to Osred, King of Northumberland, is full of Instructions very useful for Princes.
The 30th contains some for a Queen that had retired from the World.
The 31st is full of Advices to the Canons of Tours.
The 32d to the Bishop Adelbert and his Society, contains a commendation of the Life of the Canon Regulars, and an Exhortation to follow it.
The 49th contains the same sort of Exhortations to the Friers of Wiremouth and Jarrow.
The 50th to those of York.
The 62d to the Canons of S. Leger.
The 63d is directed to Pope Adrian, to whom he writes very submissively.
In the 69th he exhorts the Canons of Lyons, to reject the Errors which are come from Spain, to follow the Tradition and Usage of the Universal Church, to avoid the Additions made to the Creed, and the new Customs brought into the Service of the Church. He speaks particularly of their Error, about the Adoption of the Son of God, and the practice of some, who threw Salt up∣on Christ's Sacrifice. He maintains, they ought to Offer nothing but Bread, Water, and Wine; that the Bread ought to be very pure, without any mixture, made of Flour and Water. The last thing, he finds fault with, in the usages introduced in Spain, is, that they made but one Immer∣sion, calling upon the Three Persons of the Trinity. He maintains against them the use of the Tri∣ple Immersion, and here he explains the Ceremonies of Baptism; he speaks of the same thing in the 81st Letter, where he does intimate, that there were some who dipped Three times, re∣peating the Invocation of the Trinity at each time. He reprehends in this Letter, those who doubted, whether the Souls of the Holy Apostles and Martyrs were received up into Heaven before the Day of Judgment. In the 71st Letter he proves the necessity of Confession.
The 72d is to Pope Leo, whom he calls Vicar of the Apostles, Prince of the Church.
In the 78th he commends the Monastick Life, and exhorts Monks to discharge the Duties of it.
The 97th contains excellent Instructions about the Duties of a Bishop.
He Treats of Baptism in the 104th.
In the 106th he Answers the Question put to him by Charlemagne, which is the Hymn that Je∣sus Christ said after his last Supper. He pretends, it was the words related by the Evangelists.
Since this Edition there have been Printed some more of Alcuin's Works; as, a Commentary upon the Song of Solomon, at London in 1638, [by the care of Patrick Young.] An Abridgment of the Faith against the Arians, set forth [at Paris in 1630,] by F. Sirmondus, without the Au∣thor's Name, and attributed to Alcuin by F. Chiffletius, upon the Authority of some MSS. A long Confession of Faith, divided into Four parts, drawn out of the Fathers, published by F. Chiffletius, and Printed at Dijon in 1656, [but it is dubious whether it belong to Alcuinus, or no.] A Discourse of the Purification, which was without Name among S. Ambrose's Works, and was restored to Alcuin by M. Baluzius, in the 2d Vol. of Miscellanea, p. 382. Two Letters set forth by M. Baluzius in the same place, [Tom. 1. p. 365.] the one directed to Charlemagne, upon the price of Jesus Christ's Death; the other to the Abbots and Monks of the Goths, upon the Unity of the Two Natures in the Person of Jesus Christ. There's in the same place a Ca∣pitulary, containing sundry Moral Maxims directed to Charlemagne; but that Work seems to me unworthy of Alcuin. Twenty Six Letters published by F. Mabillon in the 4th Vol. of his Analecta. And a Poem, in which he laments the disorders and looseness of one of his Friends, under the Name of a Cuckow.
The Learned are not all agreed, that the Confession of Faith, set out by F. Chiffletius, is Al∣cuin's. The Author of the Office for the Holy Sacrament, in the Historical and Chronological Table of the Authors, hath propounded some difficulties about this Confession of Faith, which might make one doubt, whether it be truly Alcuin's. He says, the two first parts of it are very excellent and precious; but there are many things taken out of the other Works of Alcuin, especially the different Orations. That the third part does not seem to be coherent to the two first, there being several places in it copied out of them word for word; which probably an Author, whatever he might be, would not have done in the same Work. Besides, that it is al∣most all of it taken from Pelagius's Confession of Faith, and from the Book of the Ecclesiastical Doctrines, yet so, that the Pelagian and Semi-pelagian expressions of those Books are commonly left out in it; that there are also some places of it without any rational coherency: And above all, what he set in the end, to join it to the 4th, seems to have been added. That the 4th part, in what it contains about the Eucharist, is perfectly fine, but doubtless it ends in the first Chap∣ter; all the rest being but a Rapsody of divers Orations. He confesses the Stile of this last part, as well as of the first, does pretty well resemble that of Alcuin, which is not always very pure and correct, but very quick and lively. He intimates, that altho' these Four Words (Caro, Cibus, Sanguis, Potus,) which are found in S. Thomas's Prose, are read there, the Thread of his Discourse did so naturally lead him, to use them in that order, that one ought not to conclude, that this Work was made since S. Thomas's time. That the Stile hath nothing Scholastical, yea, and that it hath some expressions, which were not used since Berengarius, as, that the Eucharist is Christ's Body and Blood only for the Just. Lastly, that in this 4th part there are some places found in the Book of the Divine Offices attributed to Alcuin.
Daillaeus hath taken affirmatively, what was said but doubtfully by the Author Of the Office of the Holy Sacrament, and he adds new Conjectures, to shew that this Confession was not Alcuin's.
