Happy New Year, everyone! This Sunday, December 2, is the first day of Liturgical Year 2013, which is Lectionary Cycle C for readings on Lord’s Days and Holy Days. Obviously, it is also the First Sunday of Advent. Now, the tradition of the Church is to read the Book of Isaiah during Advent, because this prophetic book, more than any other, is regarded as a prophecy of the Coming of Christ (adventus Christi), both his first coming and his second coming. Thus, if you examine the Sunday Lectionary for Years A and B, and the weekday Lectionary for Advent, you will see that the First Readings are dominated by selections from Isaiah.
However, in Year C of the Lectionary, the Church opts to do something slightly different for a change. The First Readings for this year are taken from other important prophetic passages concerning the coming of the Christ outside the Book of Isaiah—passages that otherwise would be neglected if only Isaiah were read.
