He was born in Toulouse, Gall, and is believed to be the brother of Saint Lupus of Troyes, who accompanied Germanus of Auxerre to Britain to combat Pelagianism. Vincent entered Lérins Abbey where, c.434, he wrote the Commonitorium (Or Commonitory, "Of Things in Common"). The 5th-century priest and historian Gennadius of Massilia recorded that the Commonitorium was written in two volumes, of which the second was stolen from Vincent, who never bothered to re-write it.
This work declared what Christians had in common:
I have continually given the greatest pains and diligence to inquiring, from the greatest possible number of men outstanding in holiness and in doctrine, how I can secure a type of fixed and, as it were, general, guiding principle for distinguishing the true Catholic Faith from the degraded falsehoods of heresy.
...and he lays out the problem, listing the common differing doctrine of the day:
Here, it may be, someone will ask: "Since the canon of Scripture is complete, and is in itself abundantly sufficient, what need is there to join to it the interpretation of the Church?" The answer is that because of the profundity itself of Scripture, all men do not place the same interpretation upon it. The statements of the same writer are explained by different men in different ways, so much so that it seems almost possible to extract from it as many opinions as there are men. Novatian expounds in one way, Sabellius in another, Donatus in another, Arius, Eunomius and Macedonius in another, Photinus, Apollinaris and Priscillian* in another, Jovinian, Pelagius and Caelestius in another, and latterly Nestorius in another. Therefore, because of the intricacies of error, which is so multiform, there is great need for the laying down of a rule for the exposition of Prophets and Apostles in accordance with the standard of the interpretation of the Catholic Church.
His simple and straightforward guide was the proper interpretation of Holy Scripture must be judged by three qualities:
- Universality (they must be believed by the whole Church)
- Antiquity (they must be held from the earliest times, not new-fangled ideas)
- Consent (they must be supported by all—or almost all—of those who are considered authoritative
This idea is abbreviated in the scroll he holds in the illustration above, which can be translated "We hold that faith which has been believed everywhere, always, and by everyone."
And just like that...if the idea has been held since the beginning, if it is (almost) universally agreed upon, and if it has the support of (almost) all the doctrinal experts, then that is what we call the proper interpretation.
*I find that I have lied to my readers. Six years ago here I said in a footnote "'Priscillianism'" will be covered in the near future." It was created at the extreme western end of the Mediterranean from Gnostic doctrines coming from the extreme eastern end of the Mediterranean. It's time I fulfilled my promise...tomorrow.
