One of the vital issues in contemporary Christian theology is the problem of a renewed understanding of God's eternity and its relation to time. This is not merely a peripheral doctrinal issue, but lies at the heart of our understanding of God and humanity, and contributes to our entire worldview. This study focuses on a longstanding debate between two competing views on God's eternity: one focused on God's absolute timelessness in classical theism, and the other on God's temporal everlastingness in contemporary panentheism. In contrast to both of these well-worn options, this book presents an alternative Trinitarian analogical understanding of God's eternity and its relation to time, especially through a critical reflection on Karl Barth's and Hans Urs von Balthasar's engagement of the issue. this analogical approach, based on the dynamic and dramatic concepts of God's being-in-relation and of the Triune God's communicative action in eternity and time, has the potential to resolve the debate between absolute timeless eternity and temporal everlasting duration. - Publisher info.
