I apologize for the misunderstanding.
Not a problem.
Would not the problem with this approach be that the Bible may then be taken to mean whatever one so wishes?
Of course the bible may be taken to mean whatever one so wishes. Any literary may be taken to mean whatever the reader wishes. That does mean the author intended their words to be construed as such. Irrespective of how accurate and selective the author is in choosing their words, it is more than possible the reader may interpret what they say in a whole variety of ways. To illustrate, I am a Law student. Legislators are very particular when composing legislation. Their words can still be interpreted in a whole variety of ways. I am currently studying criminal law. My coursework is on the Theft Act, and I have just read a case were one of the Lords devotes six pages to the meaning of the word ‘appropriation’ in the Theft Act and Parliament’s intention in including the word ‘appropriates’ in the Theft Act. I have read a text book that devotes almost an entire chapter to the meaning of the word ‘appropriates’ as stated in s1 of the Theft Act. What amazes me is in relation to the bible, people seem to think God should have made things absolutely clear in regard to one word or sentence in the bible. Yes, God should have used his almighty power to ensure authors and translators wrote absolutely accurately. However, he would have to use his power to ensure everyone who read it to construe the words and context accurately. Not much room for speculative and imaginative thought their, and no room for self expression. Such a Revelation would be pretty dull. I’ve no problem with speculation and imagination. I think it’s a essential element of being human. However, one needs to recognize their personal speculation and imagination and not teach it as ‘God says’ and if you don’t agree with me you’re not only wrong but going to hell. What does not change is what God wants us to know. Yes, what God reveals is subject to human perceptions. However, does the bible not tell us this? That humans did misunderstand what God was revealing? Not in terms of principles or morals, but in terms who or what we think God is and how we think He should act? God is neither master to human hopes, desires and expectations or human will. He will do what is just and loving irrespective of what we think is just and loving. The scriptures are full of illustrations of that, and how in hindsight people realized this.
One might attribute God’s condemnation of homosexuals and his dictates that they be killed to be literally God’s true commands, or one might consider them an exaggeration of a suggestion made on God’s behalf and later attributed to him.
Does it say in scripture homosexuals should be killed? If it does, I’m aware of it. But, I could be wrong. It may say it. If it does, (and if it does I’ll bet you know where it does,

)
I can comment on it. I personally can’t think of anywhere.
If we are to consider that God really does not appear to concern himself about how we interpret his meanings (Jesus’ mild manner might suggest God would really not approve of such conduct or his avowal that all of the laws in the Old Testament should be upheld might suggest the reverse), how might one be said to be even able to grow closer to him? Is not any growth in that direction necessarily the mere growing in attachment to one’s own idea of God? What if the real thing is quite different? Quite as savage as in his OT writings, as the promise of Hell for unbelievers still suggests?
One can grow close to whatever image of God one chooses. The image we choose is not necessarily who God is. If God was not concerned about how we interpret his meanings, he would have become Incarnate. The purpose of the Incarnation was to reveal God. The best way for a human to relate to the nature of God is to put that nature in human form. Of course, it wasn’t the only reason but I won’t get into all that theology.
However, you said, and you made a good point, that to understand how Catholics think on the bible, or anything else for that matter, is to engage in dialogue with them. The Incarnation is central to the Catholic faith, and everything else hinges on it. Being an atheist you don’t believe God exists let alone became Incarnate.

However, if you want to get your head round the Catholic faith and their image of God, you need to get your head round their understanding of the Incarnation. You are free to disagree with it, but if you want to understand what makes Catholics tick, you won’t do that if you can’t get your head around their understanding of the Incarnation.
In relation to the above, of course my interpretation of scripture is problematic. If it wasn’t, it would be perfect and I would know the very mind of God. What I say is theory. No more, no less. Anyone is free to disagree. I don’t claim to be an authority on the mind of God. In fact, I’d be concerned if someone just accepted everything I said. They would be putting too great a degree on what they perceive as a good argument, rather than a true belief.
