I can suggest some books that approach Jesus Christ's message from a historical or philosophical perspective, minimizing religious bias. Here are a few options:

1. **"The Historical Jesus" by John Dominic Crossan**: This book explores the life and teachings of Jesus within the context of 1st-century Judaism and the Roman Empire.

2. **"Jesus: A Revolutionary Biography" by John Dominic Crossan**: Another book by Crossan, this one focuses on Jesus' teachings and actions as a revolutionary figure in his time.

3. **"The Gospel of Thomas" translated by Stevan L. Davies**: This book presents an alternative Christian text that focuses on Jesus' sayings and teachings, without the narrative framework of the traditional Gospels.

4. **"Jesus for the Non-Religious" by John Shelby Spong**: Written by a former Episcopal bishop, this book attempts to separate Jesus' message from traditional Christian dogma and explore its relevance for modern non-religious people.

5. **"The Power of Parable: How Fiction by Jesus Became Fiction about Jesus" by John Dominic Crossan**: This book analyzes Jesus' parables as a way to understand his teachings and their significance.

These books offer various perspectives on Jesus Christ's message, focusing on historical context, philosophical insights, or literary analysis rather than religious doctrine.

If you're still unsure what you're looking for, consider what aspects of Jesus' message interest you most:

* His teachings on ethics and morality?

* His role in Jewish history and culture?

* The historical context of his life and death?

* The symbolism or metaphors used in his parables?
