Purchase of denominational materials provides an important measure of denominational commitment. Six out of ten congregations purchase their worship, educational, stewardship and evangelism materials exclusively or primarily from denominational sources. Older and smaller congregations are more likely to purchase materials primarily from their denominations than are younger and larger congregations.
Among the faith groups, Catholic/Orthodox are most likely to purchase from their own denomination, Evangelical Protestants least likely. However, vital congregations are slightly more likely to buy outside their denomination, perhaps to support their breadth of programs and growing membership.
