The Westminster College Library of Biblical Symbolism

"This series encourages works of scholarship that explore the
artistic and theological depths of biblical symbols. "Symbol" here
means any well-known reality that is used to illuminate a more
mysterious reality by means of the analogy between the two. The
symbols can be objects, qualities, actions, roles, events, stories, or
systems. "Exploring" symbols entails: painting a full picture of the
well-known reality as the original writers and readers would have
known it; establishing what the subject of the symbol was in
particular instances; and seeing through the symbol to the depths
of the subject. The books in this series may focus on a particular
symbol (e.g. light, or shepherd, or the Exodus), on a particular
type of symbolism (e.g. Paul's legal symbolism, or Flosea's
personal symbolism), or on particular themes (e.g. the variety of
symbols used to illuminate the mystery of human sinfulness and
how those symbols are used to interpret each other). Still others
may focus on particular books, such as Ezekiel or Revelation,
exploring their main symbols.
