unchurched

adj

1. Who does not generally attend church.

   “[…] create a composite profile of the typical unchurched person your church wants to reach.”

   “Fewer young people may be interested in the Church, but the Church is definitely still interested in them. That’s how young, unchurched activists may inadvertently end up leading not only political change, but also change within the Church itself.”

2. Who has never attended church; who has not been exposed to the experience, culture, etc., of church.
