postilja

A postilja is a collection of sermons or homilies, typically intended for liturgical use or private devotion. The term derives from the Latin "post illa," meaning "after these things," referring to the practice of expounding upon scripture readings. Historically, postiljae were compiled by theologians and preachers, serving as a guide for clergy who might not have had the time or training to compose their own sermons. They often followed the liturgical calendar, providing commentary for Sundays, feast days, and other important occasions.

The content of a postilja could vary widely, ranging from simple exegeses of biblical passages to more elaborate theological discussions and moral exhortations. Some postiljae were designed for public proclamation in churches, while others were intended for reading aloud in households or for personal study. They played a significant role in the dissemination of religious doctrine and the cultivation of piety, particularly during periods when literacy rates were low.

In the medieval period, postiljae were widely circulated in manuscript form. With the advent of the printing press, they became more accessible and were printed in numerous editions. Prominent examples include the Postilla litteralis et moralis by Nicholas of Lyra and the Postil on the Gospels by John Wycliffe. While the practice of compiling and relying on postiljae has declined in modern times with the emphasis on original sermon composition, they remain valuable historical documents for understanding the religious and intellectual life of past centuries.
