LESSONS, THE

Lessons, The: translation

The word "Lesson" is derived from the Latinlectio, meaning a reading, and signifies a portion of Scripture appointed to be read during Divine service; applied especially to those Scriptures read in the Daily Services. Two Lessons are to be read at each service in accordance with the custom of the early Christians, one from the Old Testament and one from the New. The principle upon which the Lessons are thus selected is set forth by Justin Martyr, who lived A.D. 103-164, as follows: "The Apostles have taught, as they learned themselves, first the Law and then the Gospel; for what is the Law but the Gospel foreshadowed; or what is the Gospel but the Law fulfilled."
