“The Apostle Paul makes several points about specialization by demonstrating that Christians, as members of the body of Christ, are all specialists. Some are eyes; some, hands; some, feet. Some are elders; some, deacons; some homemakers are hospitable to angels. But the only reason such specialization is and can be good is that Christians do not specialize in doctrine — we all have the same mind, the mind of Christ. Thus while Paul encourages a diversity of gifts, activities, and congregations, he does not encourage a diversity of doctrine. In Paul’s school there is divine Election, but there are no electives. There is, rather, a rigorous systematic theology, summarized for us in his letter to the Romans” (John W. Robbins, The Educational Establishment versus Civilization).
