I am Christian and searching for answers also.
If you don't mind I was wondering if you could tell me what version and year that old family bible was? I would love to be able to read it with those books included! This is amazing information because like you said it means that they (who ever "they" are) took them out recently. I have been studying Gnosticism and from what I understand the bible was altered back in the early days of Christianity. The Roman church did this to have more power and control over the people. I know Christian Gnostics flourished for a while until the Church perceived them as a threat and almost wiped them out. If books were taken out of the bible RECENTLY then It really changes everything we Christians were led to believe. In my opinion.
