Latin Theological Quotes Worth Knowing: Definition of Catholicity: Quod Ubique...

This will be the first in a series of studies on important Latin theological quotes. I start with a well-known but important mainstay--the definition of Catholicity.

This comes from the Commonitorium, a 5th century Christian treatise written under the pseudonym "Peregrinus" (Pilgrim), but frequently attributed to St. Vincent of Lérins. 

Latin:
In ipsa item catholica ecclesia magnopere curandum est ut id teneamus quod ubique, quod semper, quod ab omnibus creditum est.

Literal Translation of the English:
Moreover, in the Catholic Church itself care must be greatly taken that we hold that which has been believed everywhere, always, by everyone.

It needs to be admitted that, on a practical level, this formula does not today produce any meaningful measure by which to arrive at consensus on Christian teaching. As for Catholic or Orthodox Christians, we believe plenty of things not found explictly in the Bible, and which we believe have indeed been held by the Church "ubique, semper, et ab omnibus." Despite the fact that some of these teachings can be found to be truly ancient, still most Protestants will not accept them unless they are at least implicitly found in Scripture.
