The bible has it own interpretation and understanding,the bible is also God given.No human understanding is capable of understanding or knowing the real meaning of God's word,no human mind will be sufficient to understand the bible.
Psalms 94 verses 11
The lord knoweth the thoughts of man,that they are vanity.
The thought of man,the think of man,human mind are all vanity in the sight of God. So,they are nothing.
1 corinthians 1:19 says;
For it is written,I will destroy the wisdom of the wise,and will bring to nothing the understanding of the prudent.
So,even how prudent a man can be,his understanding is nothing in relation to God's word. Now,how do we understand God's word, we have to have an understanding that is given by God. Unless it's God that gives us the understanding, we can never understand the complete meaning of God's word in the bible.
Proverb 1 verse 23 says,
Turn you at my reproof:behold,I will pour out my spirit unto you,I will make known my words unto you.
For us to know the word of God in the bible,we need the spirit from God.
Why do we need the spirit 1 corinthians 2 verses 11 says; For what man knoweth the things of a man,save the spirit of man which is in him?even so the things of God knoweth no man,but the spirit of God.
The things of God are only known to the spirit of God and by the spirit we will understand God's word.
1 corinthians 2 verses 10 says;
But God hath revealed them unto us by his spirit:for the spirit searcheth all things,yea,the deep things of God.
The deep things of God can be understood by man through the intervention of God's spirit because God according to paul. So it is by the intervention of God's spirit that we may know his words. The approach that you are talking about of churches regarding the word of God in the bible are human approach,they are misled by their wisdom.
It's through their wisdom that they will not understand God's word.
