Dr. Euan Cameron, Henry Luce III Professor of Reformation Church History at Union Theological Seminary in NYC, returns, to RCB to discuss the sacrament of baptism in medieval Christianity. Baptism was considered to begin the process of cleansing the human soul from sin, as part of a lifetime journey of purification. The sixteenth-century reformers radically changed the theological understanding of baptism to accord with a new understanding of how people were saved: baptism represented, and in a sense embodied, the entire process of salvation. However, almost immediately tensions developed in the Swiss heartland of the reformed tradition between those settled churches which baptized the young, and those gathered churches which baptized only the consciously committed. The heritage of these debates remains with us today.
