It is how you live in Christ Jesus that is all important, not just what you know. Having said this, there has been many times in and throughout history when this issue of knowledge for knowledge sake, came to a head. It was this issue of Knowledge first, over the simplicity of Knowing Jesus first that seemed to be what the battle was about.
For example, there was a time in the later middle ages when the theologians of that day had gone so far as to create a theology that no one but they themselves could understand or relate to. Their theology had become increasingly complex and stood in direct contrast to the simplicity of the gospel of the Lord Jesus Christ. As this gap widened, so did the reactions of the people. Their reactions were focused upon a theology that was fraught with an over emphasis of subtleties, developing its own exclusive and elitist language with an insistence upon precise definitions and fine distinctions, theologically.
In the book, “Imitation of Christ”, we discover what was the commonly held belief’s of the day, beliefs that were reactions against the theologians and their theology of the day. Here is a taste of it (1.1.3):
“What good is it for you to be able to discuss the Trinity with great profundity, if you lack humility, and thereby offend the Trinity?”
“Verily, high sounding words do not make one holy and just. But a life of virtue does make one acceptable to God.”
“It is better to feel repentance, than to be able to define it.”
“Were you to memorize the entire Bible and all the sayings of the philosophers, what good would this be for you without the love of God and without grace?”
“Vanities of vanities. All is vanity, except loving God and serving only God.”
