The biblical writings are writings written by men, how do we know they are fact?
With Jesus, things must have been spread orally before anyone decided to write down anything. But how was those oral teachings kept, and how do we know they were passed down accurately?
Like if in Peter's time all things were established then, with the people who saw and knew things firsthand or from them, why were there later councils to decide things? wasn't the Church and it's truths established before then? and if so how do we know they were kept accurately?
And was the scriptures explained fully then in those times, to Jews even, explaining even the old testament?
If they were and all things kept and passed down, there wouldn't be no need for anyone later to try to explain with their own opinions, all would be needed would be to pass the truth down?
I also hear of other writings about Jesus, how is it known what is true and what is not?
