The lectionary is a pre-selected collection of scriptural readings from the Bible that can be used for worship, study or other theological uses. Some congregations of the Christian Church (Disciples of Christ) use the Revised Common Lectionary which follows the liturgical year in a 3-year cycle and provides scriptural recommendations that compliment the current season of the liturgical year.

The colors of the lectionary are representative of the Liturgical seasons of western Christianity. These seasons are Advent, Christmas, Ordinary Time (Time After Epiphany), Lent, Easter, Pentecost and Ordinary Time (Time After Pentecost). The liturgical year begins with Advent.

Each season is represented by a color:

• Advent – Violet or Blue
• Christmas – White
• Ordinary Time – Green
• Lent – Violet or Blue
• Easter – White
• Pentecost – Red

Although it is customarily observed, congregations in the Christian Church (Disciple of Christ) are not required to follow the liturgical seasons or the lectionary.
