Latin Vulgate — The Church’s Authoritative Bible
Historical authority:
Completed by St. Jerome around 405 AD, the Vulgate served as the primary Bible of the Western Church for over a thousand years, shaping doctrine, liturgy, and culture.
Excerpt / significance:
“In principio creavit Deus caelum et terram.” — Genesis 1:1
(Translation: “In the beginning, God created heaven and earth.”)
Core teaching / reason for prominence:
The Vulgate is arguably the most important Catholic book ever. It codifies the faith in one authoritative corpus, but as Bishop Robert Barron points out, it is more accurately a library of books than a single book. It contains history, law, prophecy, poetry, wisdom literature, Gospels, letters, and apocalyptic vision—encompassing multiple genres and approaches to God, morality, and salvation.
Why it matters today:
Every major Catholic translation—including the Douay-Rheims and NABRE—traces its lineage back to the Vulgate. Its influence on theology, liturgy, education, and spiritual life is unmatched.
