The
preaching of a sermon following the reading of Scripture originates in
synagogue worship. "Homily" (from the Greek homilia, discourse) and
"sermon" (from the Latin sermo, talk) are synonyms. Unofficially,
"homily" is often used to mean a "short sermon." Such homilies are sometimes
provided at certain special occasions (such as weddings) or when there are time
constraints because of the scheduling of Services. "The Sermon" is listed as an
integral part of Eucharistic worship (see Prayer Book pages 326 and 358), but
not for Morning or Evening Prayer.
