Throughout the scriptures the usefulness of teachers and the requirement of ministers to be able to teach is made plain. Therefore, it would be safe to assume that ministers are to teach somebody nor merely teach empty seats. If God saw no benefit in the saints learning from gifted teachers why spend so much time on the topic of teaching in the scriptures? Secondly, consider Proverbs 11:14:

Where no counsel [is], the people fall: but in the multitude of counsellors [there is] safety.

Are not the written works of those whom the Holy Spirit has guided in past beneficial to us today? Is there not safety in Biblical interpretation when we compare our interpretations with those who have come before us?

Unfortunately, all of us have proceeded with the same ignorance that we will read the scriptures as God intended without preconceived assumptions. Therefore we errantly conclude that all those who came before us must have had an agenda. We make these judgments assuming that we are a capable final judge on the motives of those who studied before us. Granted there are right and wrong interpretations, but we must be careful that we do not hold ourselves above others in such a prideful and arrogant manner.
