Good to have another Norfolk person here.
The first thing to say about the Orthodox view of the Bible is that it is the written part of God's revelation to us, not the whole of it. Christ did not drop off a book of instructions, He founded a Church. That Church it was which discerned, in the fourth and fifth centuries, the surviving Apostolic deposit and canonised it; that same Church also decided that the Jewish Scriptures familiar to Christ and His Blessed Apostles should be added to that canon and read with it - producing the Bible.
Christians got by without a Bible for a long time, and as long as Christ's Church exists, they know that in the Church there is best illumination for what that Book means; as St. Peter tells us, no prophecy is by private inspiration.
So, the Bible is certainly the inspired word of God, but it is not, by itself, sufficient. For example, where, in the Bible, does it state what books should be in the Bible - or even that there should be such a thing as the Bible? We know these things because of the Church, which also tells us it is God's inspired word to us.
The late nineteenth and twentieth centuries saw a distressing and very non-orthodox split in the Western world between those who, influenced by the new German scholarship coming out of Gottingen, thought that the Bible was, at best, a beautiful metaphor, and those who reacted against it by asserting that every word was literally true. The OC has never taken either position because neither is that of the ancient Church.
In terms of the human ancestry of Christ, the Gospel writers use the oral testimony available to them, that that testimony clashed means simply that. Of course, if you think the thing was dictated by God, that would be very distressing and you could (and people have) come up with a complicated explanation). But if you accept it as a human document inspired by God, there is no problem.
Is there a lot of killing in the OT? Yes, but then there is, regrettably, a lot in history full stop. We are a fallen race and we need the redemption brought by the Lord.
You raise an interesting point which I'd be very happy to discuss further.
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. (1 John 4:10)
