In other words they sit in judgement on the organized churches as being "worldly" and then use that as an excuse not to assemble and learn from other Christians, and not to participate in the local ministry opportunities offered by the organized churches both local and foreign.
Every denomination and every church within that denomination has their own personality. Some are indeed dead, but most are alive and blessing their community and world with a variety of missions.
Most SANR whom I know, never consider judging other believers, but thirst for true spiritual guidance through faith in Christ.
He provides the best opportunities for ministry, both local and foreign.
