Um, how is 'trusting in your own studies and rational powers' working out for all those who trust in their own studies and rational powers and end up disagreeing with others who trust their own studies and rational powers?
I disagree with what your question implies, because what you just said implies that if you happen to have the word Catholic describe your faith, then the studies and (human) rational powers of the Catholics carry more authority wherever these (human) rational powers produce disagreement between Catholics and non-Catholics.
IMO all the problems of the many disagreements between Catholics and non-Catholics, and between non-Catholics and non-Catholics, are derived in the first place from out of this well called "rational powers" because these (human) rational powers are what cause false (and at times even irrational) conclusions among all groups, including (and probably especially) those who claim that their well is "the only true well".
But the apostle of Christ told us that "There is one body and one Spirit, even as you are called in one hope of your calling, one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in you all." -- Ephesians 4:4-6,
and Jesus said HE is THE Way, and THE truth, and THE light. (John 14:6).
So Jesus is the one and only true well.
The retail stores all counted together sell a lot of their own truth and light drawn out of their own wells of (human) rational powers.
So Paul says,
"I therefore, the prisoner in the Lord, beseech you that you walk worthy of the calling with which you are called, with all lowliness and meekness, with long-suffering, forbearing one another in love, endeavoring to keep the unity
of the Spirit in the bond of peace. -- Ephesians 4:1-3,
which my own non-Catholic observation has taught me Catholics are mostly better at doing than non-Catholics, as long as we non-Catholics don't disagree with their disagreement, or with their asserted authority.
