Perpetual Fire: Temple, Ritual, and Biblical Theology: A Chat with Mark Giszczak
In today’s episode, I am joined by Mark Giszczak(Geese-check) to speak about his book Perpetual Fire: Temple, Ritual, and Biblical Theology with Baylor University Press. Levitical law commands the priests to keep a fireperpetually burning on the altar of sacrifice. Why? This book seeks to answer this question by first exploring the ritual meaning of the perpetuity of the fire on the altar, and then using this ritual analysis as a foundation for a biblical theology of divine fire. A pattern that begins with theophanies like the burning bushand scenes of divine cultic authorization in which fire falls from heaven becomes ritually inscribed in the symbolism of temple, sacrifice and priesthood. The unquenchable fire inaugurated by God comes to function as a cipher for temple legitimacy and a token of divine presence. God alone enjoysthe prerogative to light the cultic fire that in some way represents his body.The radiance of this fiery body of God is then shared with Adam in his pre-Fall state, with Moses on Mount Sinai, and with the high priest bedecked with radiant jewels. These symbolic trajectories are eventually caught up in thetransfiguration of Jesus, who is revealed as the radiant priestly Adamic imago Dei, the cult image of the new creation. Paul's theology of resurrection then builds on these themes by depicting resurrected humanity in Christ as gloriously radiant, purified by the same fire that destroys wickedness.Finally, this theology of fire envisions Christian spirituality as an assimilation to divine fire, a participation in the radiance of Christ. From creation to the eschaton, this study illustrates the lasting theological legacy of the perpetual fire of the temple altar.Mark Giszczak (Ph.D., Catholic University of America) is Professor of Sacred Scripture and Directorof the Institute for Catholic Theological Formation at the Saint Paul Seminary of the University of St. Thomas (Minnesota).
