Bolded above. To what extent?
That would be up to the Spirit would it not?
Even for teaching that is at first glance Biblical or even technically correct, I find that it "jangles" something in me, and often later on I observe that it was not from God according to His timing and His manner. Even something that is technically, theologically true can be divisive, heretical and counter to the Spirit when used in the wrong way at the wrong time.
But if we look in the books of the Bible we find that John was pretty clear: Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, but every spirit that does not acknowledge Jesus is not from God. (1 John 4)
Matthew quotes Jesus: Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves. By their fruit you will recognize them. Do people pick grapes from thorn bushes, or figs from thistles? Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus, by their fruit you will recognize them. (Matthew 7)
and Paul shows us what this fruit looks like: But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Let us not become conceited, provoking and envying each other....
...You, my brothers and sisters, were called to be free. But do not use your freedom to indulge the flesh; rather, serve one another humbly in love. For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.” If you bite and devour each other, watch out or you will be destroyed by each other....
It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.... (Galatians 5)
Of course it is good to study, discuss and debate. But we have used theology that no person can know with any certainty as a tool to divide the body and so destroyed each other. We have, to a large degree, been enslaved by theological correctness at the expense of deep love and unity.
