Most churches require the same few custom post types for their Web sites. The Church Options plugin creates those post types with the check of a box. These post types include Events, Announcements, Sermons, Ministries, People (staff), and Verses. Most of them also have custom fields for things like dates and contacts.
For these post types and fields to be used requires a theme custom made to work with them. Themes are available at Quixotic Studios for purchase which have been custom made to work with the Church Options plugin.
