plant church
n.— «A “plant” church is another word for a startup church—a seed that planters hope will grow and flourish. Some, like Vail Christian, have “mother” churches that sponsor them. Planters are typically more concerned with people than buildings. Plant churches also can be found in Tucson homes, storefronts, malls and office buildings, but schools are by far the most popular, experts say.» —“Here’s The Church — Where’s The Steeple?” by Stephanie Innes Arizona Star (Tucson, Arizona) Apr. 9, 2006.
