How are lectionary readings determined?

Lectionary readings are determined through a systematic selection process established by various Christian denominations, often based on the liturgical calendar. These readings include passages from the Old Testament, Psalms, Epistles, and Gospels, aimed at providing a comprehensive overview of Scripture throughout the year. Many lectionaries follow a three-year cycle, allowing congregations to engage with a wide range of biblical texts. The selections are often designed to align with specific themes or events in the church calendar, such as Advent, Lent, and Easter.
