Reading Romans Through the Centuries

An interesting look at the book of Romans and how it has been interpreted in different contexts, during different times and by some of the great scholars of the church.  You can purchase this book from the Book Depository here.

Ethics of Evangelism

A very important book that argues from a philosophical perspective that proselytizing is acceptable, even within the values of our culture.  At the same time it must be done within a certain ethical framework.  You can purchase this book from the Book Depository here.

Mere Apologetics

A fantastic introduction to apologetics.  Not so much a summary of apologetic arguments but a practical guide on how to do apologetics.  Highly recommended.  You can purchase this book from the Book Depository here.

Doctrines and Covenants (Community of Christ)

This is one of the standard works of the Community of Christ, claiming to be a series of prophecies from the time of Joseph Smith, Jr. to the modern day.  Note: while there is some overlap, this is not the same as the Mormon Doctrine and Covenants.

Our Legacy of Faith

A dated but helpful history of the Reorganized Church of Jesus Christ of Latter Day Saints, now known as the Community of Christ.  Demonstrates the differences between the RLDS and the Utah LDS.

Understanding the Book of Mormon

A short but extremely helpful introduction to the Book of Mormon by an ex-Mormon.  The book is useful not in ridiculing Mormons but in equipping Christians to have productive conversations with Mormons.  You can purchase this book at the Book Depository here.

Between Allah and Jesus

An interesting and imaginary (mostly) dialogue between a Muslim and some Christians.  Peter Kreeft uses this discussion, not just to teach christians about Islam, but to teach Christians about Christianity.  You can purchase this book from the Book Depository here.
