Because your church is not the church of the scripture...Because the scripture says the Holy Spirit will open our understanding, not some fallen men from some religion...Because the scriptures tell us to search the scriptures to know we have eternal life, not a man made religion...
I could list a hundred biblical reason why one should never trust your religion, or any religion on matters of faith or authority...
Then it is clear that you understand nothing of either the Holy Spirit or the Catholic Church. And again, you demonstrate that Protestantism is not identified and organized by what it is for, but rather defined by what it is against; the Catholic Church.
“Because your church is not the church of the scripture...Because the scripture says the Holy Spirit will open our understanding”
You know not of which you speak as the Catholic Church believes in the inerrancy of the Bible.
