So some of the OT authors made mistakes? No wonder you have your opinion of the Bible. If there is even one mistake, how could you know what to trust? I suppose the Church will tell you what parts are OK and what parts are no good. You said that Christ says that "eye for an eye" is not what we should follow. Here is something else Christ said:
Matt. 5:17-18 : 17 "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.
What is my opinion of the Bible, FK? You probably mean the Old Testament, which says (Exodus 21:24) "Eye for eye, tooth for tooth, hand for hand, foot for foot..."
as opposed to the New Testament, which says (Matthew 5:38-39) "Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also."
and
Matthew 3:43-45 "Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust."
These are direct references to what's in the Old Testament, and direct corrections what it says verbatim and in spirit.
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them...
Fulfilling the the law of God is love (Rom 13:10); it's not a book.
Then I assume all the males in your church are circumcised?
