USA TODAY: ‘House churches’ keep worship small, simple, friendly

Paul is writing not only to the Galatian elders. He’s writing to the whole church. And he’s saying that the church is responsible to evaluate the teaching that comes from the pulpit. They are not to passively accept anything that comes out of the preacher’s mouth, but are to hold it up to the light of Christ and test it by His Word. And if the teaching fails the test, the whole church is responsible to quit listening to the teacher – even if that teacher is an apostle like Paul himself. — 9marks.org
