while scripture is 100% accurate, it is not necessarily 100% complete. While the church never changes scripture, she certainly knows that things happened that were not recorded. Tradition, word of mouth (which is the source of most scripture) certainly play a significant role in church history. Just because someone didn't write it down, doesn't mean it didn't happen.
isn't there a passage in the bible that states exactly that.....many things happened which are not recorded here???
At least you have a lot of company in that belief. That should make you feel good. Catholics, Muslims, Mormons, and many others have revelation that is added to what they consider scripture. I know that Catholics like that belonging feeling of large numbers.
That does not give people license to fabricate stuff and claim it's the truth.
If they want to make stuff up because if makes them feel all warm and fuzzy inside and people want to believe it for same reason, then nobody is stopping them.
But the minute they try to pass it off as Truth on par with Scripture, it's not going to go unchallenged.
