This is an honest and sincere question directed to all non-Catholic Christians.
How can you tell if you are interpreting Holy Scripture correctly? A Catholic can tell because the Church has magisterial authority.
Here is an example. If a Catholic reads Genesis 1:1 and concludes that God did not create the Universe of out nothing, the Church can say that is not correct and point to various documents which interpret that scripture verse. Or if another Catholic wants to claim that homosexual act are not sinful, the Church can correct them on that too.
But when a protestant reads a verse from the Holy Bible, say James 2:17
Even so faith, if it hath not works, is dead, being alone.
and, to avoid confusion over words, here is the Latin:
Sic et fides si non habeat opera mortua est in semet ipsam
How do you know you are interpreting the verse correctly?
Please note, I am not asking for an explanation of this verse, I am asking for an explanation that you know you are right. And please be a little more firm than merely saying “by the Holy Spirit”. I am looking for an empirical and objective confirmation of how you interpret Holy Scripture.
