Pick up a Catechism for starters ONLY.
I can't spend years here explaining the original interpretation of Christianity.
You could also go ask a priest any question you like.
The Authority the non-Catholics are missing was the one Christ set up on earth using Peter as the first Pope.
All these off shoot versions of Christianity broke away due to various sins and the result many years down the road are all these lost souls who try and interpret what they think something means through their own eyes practicing a humanism version of Christianity.
Get a Catechism and that will help you quite a bit regarding all the detail you wish.
Also, Catholics are on the same page regarding the gospel and Bible passages read every day at mass. The same reading are read all over the world. There is order and meaning to everything.
You go into many break off faith churches and they are on all different pages preaching their own version of Christianity that Christ did not leave them.
The one important thing that saves them is they accept Christ as their Lord and Savior for their salvation. That key point is the thing that keeps them Christians.
Thank you for taking the time to converse with Me.
It really explains a lot of questions I have had about Catholicism. You have put some things in perspective. It has been a very long time since I have discussed theology with anyone. Most people don't really want to think about it, let alone discuss it. GA is home to some really bizarre religions (Cults?)
I have seen some real evil in my life and watched miracles happen in front of my eyes. When I was looking for a church home, I searched many denominations to find one that would teach the entire Bible, not just the parts they wanted to hear. Finding a church where the Holy Spirit is alive and in charge has been a challenge.
I was brought up Lutheran, but the church we went to was falling apart and I really believe my sister turned to paganism because of the failure of the church to reach her and my parents insistence on staying there. I pray for her all the time.
I have always been impressed with Martin Luther's courage to stand up the most powerful man of his day and declare is faith. Wrong or not, he was a courageous man.
