It was a sermon on good works for all practical purposes. Almost anyone hearing it could sadly say with surprise when informed, that they thought it was Christian sermon.you didn't answer my 1st question.
what's your definition of a 'fundamentalist church' ?
it doesn't sound like you heard that in a Christian church (one that believes in and teaches scripture), unless the teaching was against 'good works' devoid of Christ.
As far as what is a fundamental church goes, I would say they exist from Baptist varieties to charismatic circles and everything in between. Just because a group may fall into that category doesn't mean the preach good works devoid of Christ but enough of them if not many do. Suffice to say a non-reformation church setting. I've belong to different ones.
