Did God Become Man: The main purpose for writing this booklet is to reach those who believe in God and cause them to reflect on the nature of their beliefs in the light of reason and revelation.

The positive response of the varied audiences to this lecture encouraged me to prepare it as a booklet in order to make it accessible to a wider audience.
