A great resource from Southern Baptist Theological Seminary. Mohler has written a short eBook on the pastor’s role as theologian. Here’s the money quote for me:

…the pastor must learn to discern different levels of theological importance. First-order doctrines are those that are fundamental and essential to the Christian faith. The pastor’s theological instincts should seize upon any compromise on doctrines such as the full deity and humanity of Christ, the doctrine of the Trinity, the doctrine of atonement and essentials such as justification by faith alone. Where such doctrines are compromised, the Christian faith falls. When a pastor hears an assertion that Christ’s bodily resurrection from the dead is not a necessary doctrine, he must respond with a theological instinct that is based in the fact that such a denial is tantamount to a rejection of the Gospel itself.

Pastor or not, go get yourself a copy.
