against heresy

Martin Downes nails this one. Here are his conclusions regarding how we are to deal with (or not) heresies.

1. Ministers must be polemical in their public teaching when they need to be, but not otherwise. In the course of expounding passages dealing with these matters, and when there is real threat. In their private study there is of course need to be aware of men and movements that are dangerous. This is not an appeal for ignorance or dropping our guard.

2. Congregations should be spared from hearing about the specific details of false teaching unless it is absolutely necessary. There are winds of doctrine in the evangelical world, but are they affecting us? Should we not concentrate on things that are? If false teaching is unprofitable and worthless what good can come from considering it? Should we not look at our own sins and situations and address those issues instead?

3. Concentrate on the positive upbuilding of the church. There is work enough here. The rest of 1 Timothy expands on this. Buchanan says that truth is one, more is gained by the positive exposition of the truth than by detailing the forms of error which are multiple. Don't waste time on matters that are not a threat to your situation. The time is short. Is that not how Nehemiah treated his opponents? Put good things before the church and have nothing to do with silly, irreverent myths (4:6-7).

4. Guard your heart and your ministry. As Francis Schaeffer once wrote, reflecting on the battle for the gospel in the 1930s, “be careful what habits you pick up in controversy”. Dr. Lloyd-Jones made the same point in his discussion with T. T. Shields. A polemical ministry is necessary, we must contend for the faith, but we must guard against a contentious spirit. Preoccupation with error is not good for the minister or the church. This is Paul's charge to Titus. The gospel of salvation is excellent for people, the root of faith promotes the fruit of good works. This is profitable. But these other teachings are unprofitable and useless. Avoid them, they thrive in an atmosphere of contention (Titus 3:9-11).
