People do need to learn from those gifted as teachers and called to “shepherd” the church. But I have noticed this to be problematic at times (depending on the student, the mentor, and the method). Unfortunately, what is often put forward as “help” in interpreting the Bible is the offering of a “correct interpretation.”
We’ve seen this expressed repeatedly on this forum. "God gave these men to the Church as teachers, therefore God gave their interpretation and doctrine to the Church." The problem, obviously, is that there is no consensus between “these men” and if that were a true statement then it would deny itself across denominational divides. Mentors are certainly useful, but like commentaries then too can be misused and elevated. Even the best scholar is at danger of applying their bad ideas into their inductive research (and all probably do this to some extent).
People need to be taught biblical literacy. People need to learn how to study Scripture. Our church as a whole need help learning how to interpret the Bible, not relying on the interpretation of others. Some of the best mentors I’ve had actually refrained from revealing many of their positions on theological issues so as not to “corrupt” the learning process. Relying on the studies of another only facilitates biblical illiteracy.
