Theological Task Force: Unity and purity
Also featured in the Outlook forum this issue: The challenge of true compassion by Tim Filston
For my first Homiletics sermon at Westminster Theological Seminary my text was Paul's challenge to the elders of the church, in Acts 20:28-31: Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he has bought with his own blood. I know that after I leave, grievous wolves will come in among you and will not spare the flock. Even from your own number persons will arise and distort the truth in order to draw away disciples after them. So be on your guard!
At the time I preached that sermon, I was sure that the current meaning of "wolves" was "Protestant Liberals," who had explained away much of the text of Holy Scripture. After decades of historical research, I have not changed that opinion. However, I have learned that religious wolves come in many shapes and sizes. Left to ourselves, acting without the restraining or inspiring grace of God's Spirit, any of us can tear and divide the flock. A great hymn, "The Church's One Foundation," describes it:
Though with a scornful wonder
This world sees her oppressed,
By schisms rent asunder,
By heresies distressed ...
When Luther wrote his first commentary on Galatians (1519), he was concerned to confront both heresy and schism. He knew that the leadership of the church was riddled by sexual antinomianism and other deadly sins, and that it was involved in theological heresy that had corrupted its center in Rome.
