A homily is a type of explanation given after a Bible reading. It provides a public explanation of religious teachings or sacred texts. The writings of Origen and John Chrysostom, especially the Paschal Homily, are examples of well-known Christian homilies.

In Catholic, Evangelical Lutheran, Anglican, and Eastern Orthodox Churches, a homily is often given during religious services, such as Mass, Divine Liturgy, Holy Qurbana, or Divine Service. It is usually presented at the end of the part of the service where scripture is read. Many people think of a homily as being the same as a sermon.

The English word "homily" comes from the Ancient Greek word "homilia," which means talking with others or interacting (from the word "homilos," meaning "a gathering"). This word appears in 1 Corinthians 15:33, where it is used in the phrase "wicked homiliai corrupt good morals." The related verb appears in Luke 24:14 (as "homiloun") and in Acts 24:26 (as "homilei"), both meaning "to speak with." Over time, the word took on a more specific meaning. According to The Catholic Encyclopedia, Origen was the first person to clearly separate the terms "logos" (meaning "word" or "sermon") and "homilia" (meaning "a type of written discussion").

Roman Catholic Mass homily

The General Instruction of the Roman Missal (GIRM), the official document that guides how Mass is celebrated, explains:

• The Homily is part of the Liturgy and is strongly recommended because it helps people grow in their Christian lives. It should explain a part of the readings from Sacred Scripture or another text from the Ordinary or Proper of the Mass for that day. It must also consider the mystery being celebrated and the needs of the people listening.

The GIRM and the 1983 Code of Canon Law say that the Homily must be given only by ordained ministers (bishops, priests, and deacons) and never by lay people. It is required on Sundays, Holy Days of Obligation, and Masses where a congregation is present.

Other senses

Modern Protestant religious leaders often use the word "homily" to describe a brief message, such as one given during a wedding or funeral. In everyday, non-religious language, "homily" sometimes refers to a message about practical matters, a lesson about right and wrong, or a general piece of advice. However, the word "sermon" is more accurate and commonly used in these situations.
