How would it be explain, say in theory, if someone came acrossed a Bible on their own with
no bias' at all. They know nothing of the Bible. He reads it and learns about it. Becomes a Christian in the sense of the teachings of the Bible.
Then went into a society where CC resides and visits. Hearing his story, say he rejects CC and moves on elsewhere. Knowing he has read the Bible on his own and knows it inside and out, yet were to reject the CC... What would you think?
Just out of curiosity!
that's pretty complex...
about fullness of faith - just linking it back to the previous topic
this person would not have the fullness of faith because - faith and Scripture are only
two parts of it.. there's also Church, Sacraments, etc. God gave us many things to help us, because He knows it can be difficult to persevere in salvation or really grow spiritually (be sanctified).. all these things help us, because God uses them to give us graces
about your example:
I think that personal understanding of the Bible is not always the best. Many have started their own denominations or even separate religions because they relied so much on their own understanding. If you just pick up a Bible and read it, you'll see lots there about faith, and then some other passages about works.. and just from my experience, that can be difficult to put together. When I first read the NT, I wasn't really in any church, and I couldn't really reconcile Paul's words about salvation by faith and James 2.. then I met some Christians and they told me that we're saved by faith alone, and I thought, well they probably understand it better than I do. So I began believing this. Sometimes I'd get worries when I read about the sheep and the goats or James 2.. and some other passages.. but I tried to rationalize.. My pastor (I went to a non denom. church) made pretty good sermons, everything made sense. I believed him on everything. Then I started to get uncomfortable about some things and began praying, and eventually my beliefs started changing somehow, so I left that church and began looking for a new one.. and here I am.. lol.. so that's just my story. My point is - it's quite possible to misunderstand the Bible, because SO many different interpretations are possible. Remember how even the devil used Scripture to back up his statements. I believe God gave the Church the authority to interpret Scripture. Another point.. which translation is that person reading.. there are Bibles that say "faith alone", but this was actually inserted there by Martin Luther and no Bibles before the Reformation had that word "alone". Grace alone, yes, but not faith alone. So things like that could be misleading too. And I don't believe a person ever comes to their beliefs entirely on their own.. for example, with me, I read the Bible before I even really knew any Christians, but once I met some, they still influenced my interpretation of it.. I guess what I'm saying is that it's complex
Also, I'd have to ask WHY this person rejected the CC. Is it because of a huge theological difference. Or is it that he/she doesn't like the liturgy or thinks it's too traditional or sees "extra stuff" like veneration of relics? is it just not their style?
Cause that relates to my story too... another reason I became a Protestant when I first found my faith, even though I was baptized Orthodox as a child, is because I thought the modern churches were more "vibrant" and "interesting" and the worship was more "heartfelt". I believe that the Protestant church is where I needed to be
at the time. I wasn't ready for all the other stuff. But eventually God showed me that it's true, and now I see that the liturgy is also beautiful and the worship is spiritual and sincere.. So - maybe this person in your example is supposed to start out Protestant, cause it fits him better and would help in his initial spiritual growth, but eventually God might lead him someplace else.

So that's why I said we should always be open to God's will. Cause we never know what He might tell us next.
This is difficult to understand for some but there are times when God leads people to Protestant churches cause that's where they need to be at the time. But that time might not be forever.
God bless
