This book is the fruit of a close collaboration between three leading scholars with a background in systematics, philosophical theology and ethics. It sets out a new account of how incarnation is mediated in the world of space and time, leading to a new orientation of theology within the world. The doctrinal ("from above") and philosophical ("from below") sections lead to a new exposition of Christian life in confrontation with deepseated problems of ethics and justice. The three pieces closely interweave with each other in the elaboration of a new kind of practical, doctrinal theology of full philosophical integrity.
