So all the other translations on earth have it wrong except the Vulgate...interesting...
No of course the translations done much later are more accurate than the one done in 382 AD, and more specifically to your point, "This passage is not about Mary", your non-infallible interpretation of that passage surely is correct rather than that of the early Church fathers. After all we moderns are much better able to discern God's revelation 2000 years removed from Our Lord's incarnation than those men who were taught by the apostles, and those men taught by those men who were taught by the apostles...etc. /sarcasm
It seems the United States Conference of Catholic Bishops disagrees and supports this version which is quite different
The USCCB as an organization on its own has absolutely NO authority. The charism of infallibility does not attach to associations of bishops. Bishop associations as any kind of governing body in the Catholic Church are a novelty of modernity, an attempt to diminish papal authority. Really. Their opinion has no weight on its own, unless it conforms to what has always been taught by the Church. And its a good thing too considering that many of the US bishops are apostates.
