You’re right. The Holy Spirit worked through the Catholic Church, the One, True, Church, started by his son, to formulate the Holy Bible.
God used many who will never see eternal life to further His cause.
By asserting such you condemn your own church.
Your first instinct was to take credit for God’s word and work. Such statements as we invented, wrote, saved, made, interpreted, and what ever other word says a lot about the spiritual maturity of some posters. God uses all types of people, things, and institutions for his good will and purpose. Just because you have been used or will be used is NOT any indication of your Salvation or your status in God’s eye.
Romans 9:17 New Revised Standard Version Catholic Edition (NRSVCE)
17 For the scripture says to Pharaoh, “I have raised you up for the very purpose of showing my power in you, so that my name may be proclaimed in all the earth.”
Romans 9:20 New Revised Standard Version Catholic Edition (NRSVCE)
20 But who indeed are you, a human being, to argue with God? Will what is molded say to the one who molds it, “Why have you made me like this?”
Unfortunately for your denomination the very Bible that you claim so much disagrees with your Catechism and condemns your faith. That Scripture is the Holy Spirit screaming at you come out of her and save yourself.
