1/ Without the bible does Jesus still retain His truth? Yes.
2/ Is He literally son or just adopted son, physically or just spiritually. Literally, both.
3/ How do you come to Christ? Where is He - everywhere , nowhere? Could you come to Him if you lived in Stonehenge while He hung on the cross? Cornelius was able to do so while giving alms in pagan temples. He is not far off from each one of us. Yes, you could come to him if you lived in Stonehenge.
4/ Can you be saved in ignorance? No. But knowing of Christ does not require the Bible. The Bible just makes it easier.
5/ Is He risen (could He die? - did the universe have a period without its triune God?). Is the Truth physical or is that a form that is created at will and discarded at will (is Catholic transubstantiation therefore possible?) If you met Jesus today would you see God, a dove, a man with physical form? What is the resurrection if the body is non-permanent anyway?
Yes, he is risen. Yes, the universe had a period without its complete trinity. The truth is spiritual and physical manifestations are created and discarded at will, therefore Catholic transubstantiation is possible. On that note, physical manifestations of all sorts wink in and out of observable/testable existence continually. The form in which you would "meet" Jesus is nonessential. The resurrection is the standing again of a person, not the standing again of a body.
6/ Can you be saved in your sins or must you be saved from your sins? Did Jesus save backslidders? Yes, you can be saved in your sins. The freedom of Christ can be used for the flesh. Paul simply counsels that it not be used that way. Jesus saved the whole world, including "backsliders;" all that is incumbent upon an individual now is to truly accept that salvation.
7/ How does the 'truth' manifest itself today , via a bible, via speaking in tongues, with prophecy or by personal revelation, by anointing with fire or by the rite of baptism? Is the truth found in all christian churches, all protestant christian churches or is it more generic than that - is the truth merely found in believers no matter what they belief (be they of any faith whatsoever?). He manifests himself however he wills. The truth is not bound by religious dogma, nor by any barrier. If He was bound in this way someone would have to be exposed to a representative of that religion in order to find the truth, the way, and the life. Jesus is not far off from anyone.
8/ How does the truth propagate itself - door knocking, bookstores, preaching, dreams, organisation, anointing or calling? He propogates an understanding of himself in whatever way he chooses. Visions on a roadway to Damascus. Opening jail doors. Inspiring writers. Even the stones could cry out.
9/ Does the truth dwell within our without can it be lost or found? We dwell within the truth, we become one with Christ. Once found, it cannot be lost. It can only be intentionally rejected by force of will.
