On the Vulgate

Peter Cousturier [Peter Sutor] said:

... if in one point the Vulgate were in error the entire authority of Holy Scripture would collapse, love and faith would be extinguished, heresies and schism would abound, blasphemy would be committed against the Holy Spirit, the authority of the theologians would be shaken, and indeed the catholic Church would collapse from the foundation.

Quoted in Jenkins and Preston, Biblical Scholarship and the Church: A Sixteenth-Century Crisis of Authority (Ashgate, 2007) p27 from Bainton (1972) pp167-8

You will be pleased to know this is of course not true, by the way!
