From Edmund Schlink's Theology of the Lutheran Confessions:
"Before one can be a father he must have been a child and a youth. No one can become a teacher who has not first become a pupil. It is as a pupil instructed by the church's interpretation of Scripture that the theologian must himself interpret Scripture in the church and instruct the church. The pupil status is never at an end. Every teacher remains all his life a child of his mother, the church."
