The English word homily is derived from the Ancient Greek word ὁμιλία "homilia", which means intercourse or interaction with other people (derived from the word "homilos," meaning "a gathering"). The word is used in ("wicked "homiliai" corrupt good morals"). The related verb is used in (as "homiloun"), and in (as "homilei"), both used in the sense of "speaking with". The word later came to have a more technical sense. According to "The Catholic Encyclopedia", Origen was the first to distinguish between "logos" (sermo) and "homilia" (tractatus).
