A
Reader in a
Christian Science church is a member of the congregation who has been elected to serve in one of two positions responsible for church services. Each week's sermon in Christian Science churches is outlined in the
Christian Science Quarterly, prepared months in advance, and is the same in all Christian Science churches, worldwide. A
lay church, it has no clergy; rather, the sermons consist of passages from the
Bible and the Christian Science textbook, are studied as lessons during the week and are read aloud to the congregation on the Sunday following.
