Context and question: Presbyterianism is historically a confessional tradition. This has two implications. The obvious one is that confessional churches express their faith in the form of "confessions of faith," which have some level of authoritative status. However this is based on a more subtle point: In confessional churches, theology is not solely an individual matter. While individuals are encouraged to understand Scripture, and may challenge the current institutional understanding, theology is carried out by the community as a whole. It is this community understanding of theology that is expressed in confessions.

Hines—culminating with Houston's tallest skyscraper, the 75-floor, 1,002-foot (305 m)-tall JPMorgan Chase Tower (formerly the Texas Commerce Tower), completed in 1982.
