The question of what was in Christ's mind and heart during his life on earth is one which people frequently ask. The complexity of the issues which such a question raises is often not appreciated, yet it is a subject which affects how other apparently unrelated questions, such as the ordination of women and the nature of church and sacrament, are considered. The Knowledge of Christ provides a comprehensive analysis of this historically controversial issue. It is a journey through the history of the discussion, not hesitating to enter, as the need arises, into different branches of study, such as exegesis, patristics and philosophy, and finally focusing on contemporary discussion.
