W3C Sites is a collection of web sites created by designers that conform with the W3C standards, or as they advertise:

7,725 Sites, 4,326 Designers, 102 Countries, 1 Goal

In English, this means W3C Sites is to you a collection of web site examples and templates to help your church web site conform to W3C standards.

This means you have no excuse not to be doers of the code, instead of just readers.
