(1) Ministry and theology are two distinct and different things. Both are valuable.
(2) Ministry is to theology as the practice of medicine is to biology.
(3) Ecclesiology can be either useful or hindersome to both theology and ministry.
(4) Theology is the pursuit of knowledge. Ministry is the taking of action.
(5) Theology values precision over time. Ministry values time over precision.
(6) Theology informs ministry. Ministry applies theology.
These theses can be seen in a concrete example. A pastor might need to decide whether to invite a specific person to receive the sacrament. This is a well-known topic; scholars write books about it and debate about it. These discussions and publications can stretch out over years.
But in the moment, the pastor must make a decision, and in some cases must make the decision quickly. In a minute, he must take action regarding a topic which the scholars have dissected for years.
This is not to say that the pastor should despise theology; on the contrary, it is for this moment that he has studied theology. Nor should the theologian despise the pastor; the theologian’s task is to provide a toolbox of concepts which are available to the pastor as he does ministry.
These theses are starting points, not conclusions.
