He hath composed an excellent Treatise against the Hereticks, in which he hath given very infallible Rules and convincing Principles to distinguish Error from Truth, and the Sects of 〈◊〉〈◊〉 Hereticks from the Catholick Church. But his Humility made him conceal his Name, and he published his Treatise under the Title of a Commentary made by Peregrinus against the Hereticks. It was divided into two parts, but the 2d. being lost, he contented himself to make an Abridgment of it.
He proposes to himself, in this Commentary, to gather the Principles of the ancient Fathers against the Hereticks. He tells us, in the Preface, That it was the Usefulness of the Work it self; the time and the place that he lived in, and his Profession, that engaged him to undertake this Work. The time, because all things here below being carried on with such a swiftness, it is reasonable that we should snatch up something that may stand us in stead in another Life, and so much the rather because the terrible expecting of the last Judgment (which he thought ••igh at hand, because that the Barbarians had made so great a Progress into the Empire) ought to stir up the Zeal of the Faithful for Religion, and the Malice of the Hereticks ought to oblige the Orthodox to stand upon their Guard. The place also was very suitable for such a Work, because, being distant from the noise and crowd of the Cities, retired in a pri∣vate Village, and shut up in the Cloysters of a Monastery, he was able, without Distraction, to do that which is said in the Psalm, Attend ye, and see, that I am your God. Lastly, no Em∣ployment can be more agreeable to a religious Life, which he professed. He therefore under∣takes to write rather as an Historian than an Author, what he hath learned from the An∣cients, and they have entrusted to their Posterity. He advertiseth us, That his design was not to collect all, but only to offer to our observation what there is most necessary.
Entring then upon his Matter, he saith, That he hath learned from many Learned and Holy Persons, That the means to avoid Heresie, and adhere stedfastly to the true Faith, is to ground themselves upon two Foundations, 1. Upon the Authority of Holy Scripture. 2. Upon the Tradition of the Catholick Church. But perhaps some will demand, saith he, the Canon of the Holy Books being perfect and sufficient of it self to settle all Religion; why is it ne∣cessary to join the Authority of the Church with it? He answers, 'Tis because Holy Scripture having a sublime sence, is differently explained; one understands it after this manner, and another after that, insomuch, that there are almost as many Opinions about the true meaning of it, as there are Persons. Novatian understands it one way, and Photinus another. It is necessary then altogether upon the account of the subtile Evasions of so many Hereticks of se∣veral sorts, in interpreting Scripture to take the sence of the Catholick Church for our Rule. But yet we must be careful to choose out of those Doctrines, which we find in the Church, such as have always been believed in all places, and by all true Christians; for there is indeed no∣thing truly and properly Catholick, as the Name in its full signification doth denote, but what comprehends all in general. Now it will be so if we follow Antiquity, unanimous Consent and Universality. We shall follow Universality, if we believe no other Doctrine true, but that which is taught in all Churches, dispersed through the whole World. We shall follow Antiquity, if we depart not from the Judgment of our Ancestors and Fathers. Lastly, we shall follow unanimous Consent, if we adhere to the Opinions of all, or of almost all the Ancients. But what shall an Orthodox Christian do if some part of the Church apostatize from the Faith of the whole Body of the Church? There is nothing to be done but to pre∣ferr the Doctrine of the whole Body that is sound, before the Error of a rotten and putrefy'd Member. But what if some new Error is ready to spread it self, I do not say, over a small part, but almost over all the Church? We must then be sure to cleave close to Antiquity, which cannot be corrupted with Novelty. In fine, if among the Ancients we find one or two Persons, or perhaps a City or Province in an Error, we must preferr the Decrees of the ancient and universal Church before the Rashness or Ignorance of some Particulars. But if there arise any Question, to which we cannot find a Parallel Case, we must then consult the Judgments of the Ancients, and compare together what those Authors have said at several times, and in di∣stinct places, who being in the Communion of the Church may be esteemed Teachers worthy of Credit, and not only to rely upon what one or two have said, but what they all have held, written and taught unanimously, clearly, and without contradicting themselves at any time. To these Rules Vincentius Lirinensis had added these Examples. The Example of the Dona∣tists he uses to prove, That we ought to keep to the Universality; that of the Arians, That we must cleave to Antiquity and reject Novelty. The Opinion of S. Cyprian about the Rebap∣tization of Hereticks, he makes use of to shew, That we must not always follow the Senti∣ments of one particular Ancient, but we may be Hereticks in maintaining the Doctrine which one Orthodox Doctor hath taught, wherefore we must depend upon Consent and una∣nimous Agreement.
Photinus, Apollinaris and Nestorius, are also brought for Examples of Hereticks, who were unfortunately mistaken by departing from the Tradition of the Catholick Church. The Fall of Origen and Tertullian may be a Warning to all Christians how they lean upon the Autho∣rity, or Reputation, or Learning of any private Person, and forsake the Doctrine of the Universal Church. Vincentius Lirinensis after he hath enlarged, as much as was possible, upon these Examples, returns to his Principles, and maintains, That we ought to keep our selves to the ancient Rule of Faith, and ought not at any time to seek after or propagate any new Do∣ctrine
