After finishing my Sacramental/Liturgical Guided Reading class, I’ve come up with a few definitions.
Liturgy: The event/experience of ontological space and action that functions as a Christological matrix of the grace of God.
Sacrament: Grace/gift/experience and understood by Christians in liturgy.
Sacramental: Experiencing the event of Grace.
The books that helped develop such an understanding were:
The Sacraments in Protestant Practice and Faith by James F. White
Liberating Rites: Understanding the Transformative Power of Ritual by Tom F. Driver
The Eucharist and Human Liberation by Tissa Balasuriya
Extravagant Affections: A Feminist Sacramental Theology by Susan A. Ross
Beyond Ritual: Sacramental Theology after Habermas by Siobhán Garrigan
Doors to the Sacred: A Historical Introduction to Sacraments in the Catholic Church by Joseph Martos
Symbol and Sacrament: A Sacramental Reinterpretation of Christian Experience by Louis-Marie Chauvet
