Everyone knows that Advent is about waiting, but author William H. Petersen asks, What Are We Waiting For? In this book, he argues for a liturgical renewal in the life and mission of the Church by proposing an expanded, seven-week observance of Advent, taking its cue from the shape and substance of the Revised Common Lectionary, while noting (and critiquing) the Church's complicity in the "Christmas culture." Resources for a more authentic observance of Advent (other than a simple short four-week count-down to Christmas) are proposed and presented. With a renewed emphasis on eschatological formation into the Body of Christ during an expanded season, this counter-cultural approach gets beyond the secular and commercial Christmas preparation madness. Instead, it provides the Church (and the seasonally harried Christians who make up the Church) with the opportunity to enter each new liturgical year not simply as engaging a routine cycle, but with ever deeper understandings, broader horizons, and higher expectations in furthering our life and mission as reflection and agent of the Reign of God/Kingdom of Christ.
