The first question...would any of them be wrong?
If someone is wrong...how do you know? Who gets to decide?
Does one group of theologians have more claim over the scripture than another group of theologians?
Does someone who has no classical, or professional, theological training have claim to the knowledge and interpretation of the scripture?
If so, who decided that? If not, why not, who says so?
Could there possibly be one single truth-full interpretation of the Holy Bible?
If a Bible teacher or preacher opens his, or her, mouth to explain the scripture, that person is making claim to the knowledge and interpretation of it.
All Bible teachers and preachers make claim to the knowledge and interpretation of the scripture.
Another question...do all Bible teachers and preachers know the Author of the scriptures?
"But as it is written: 'Eye has not seen, nor ear heard, nor have entered into the heart of man the things which God has prepared for those who love Him.' (Isaiah 64:4). But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the spirit of the man which is in him? Even so, no one knows the things of God except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. These things we also speak, not in words which man's wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned. But he who is spiritual judges all things, yet he himself is rightly judged by no one. For 'who has known the mind of the LORD that he may instruct Him?' (Isaiah 40:13). But we have the mind of Christ." (I Corinthians 2:9-16, NKJV)
Do all Bible teachers and preachers make claim to know and understand the nature and intent of God? If so, who corroborates their claim?
Only God can corroborate that claim. May God have mercy on the soul who makes claim to be a Bible teacher or preacher and to know the nature and intent of our God Who is the Author of His Word.
"Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven. Many will say to Me in that day, 'Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?' And then I will declare to them, 'I never knew you; depart from Me, you who practice lawlessness!'" (Matthew 7:21-23, NKJV)
Being that God is the only true One who can corroborate the claim of the teacher, do we have a right to judge the teacher, knowing that the ultimate judgment of the teacher or preacher belongs only to God?
Jesus also said of leaders and teachers, "You will know them by their fruit.." (Matthew 7:16, NKJV)
We are admonished to discern their fruit. This is why we can follow after some teachers and should not follow after others.
God, being God, knows the heart of the teacher, as well as, the learner, the child of God. The responsibility of the teacher or preacher is as such that he, or she, is completely accountable to God for their teaching whether it come by word or conduct.
"...Whoever receives one such child in My name receives Me, but whoever causes one of these little ones who believe in Me to sin, it would be better for him to have a great millstone fastened around his neck and to be drowned in the depth of the sea." (Matthew 18:5-6, ESV)
We are also to listen to an approved worker, "Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth." (2 Timothy 2:15, ESV)
All make claim, but only God is the ultimate judge.
Or, do we need another Inquisition in order to keep who we believe to be the false teachers away from those who could follow Christ, rather than following a false teacher into hell?
As for me, it is to preach the truth of God and let God be God.
