Nearly thirty years ago, George Lindbeck wrote his seminal and highly influential work The Nature of Doctrine. Since that time, there has been no serious attempt at moving beyond the problems he lays out, in particular the problem of foundationalism. Upon This Rock is not merely a response to George Lindbeck's important work; it is an attempt to show how theology and religious discourse can truly move past the particular problems posed by foundationalism--the assumption of and search for so-called objective and universal standards--by looking at just one important discussion within the field: the modern discussion on the nature and function of doctrine. Upon This Rock offers an account of doctrine--an account that includes such topics as the authority of Scripture, biblical interpretation, and the role of the Church and the nature of her doctrine, among others--that moves the Church past the problems of foundationalism and back to her one true rock: Jesus Christ, her Lord.
