Dean Taylor and his wife Tania were both in the U. S. Army when they realized that, as committed Christians, they had to come to grip with these question in a new and sincere quest for truth. They were determined to follow Jesus Christ under the banner of "no compromise". As they began to search the Scriptures and church history, they came to the star-tling discovery that the Christian Church originally was uniformly opposed to Christians going to war or joining the military.

In A Change of Allegiance, Taylor takes the reader on a moving journey through the Scriptures, Christian history, and his own life’s story—demonstrating the incompatibility of Christianity and war. Ultimately, Taylor challenges his readers to consider where their allegiance really lies.

As Bender explains, “The Anabaptists retained the original vision of Luther and Zwingli, enlarged it, gave it body and form, and set out to achieve it in actual experience. They proceeded to organize a church composed solely of earnest Christians, and actually found the people for it. They did not believe in any case that the size of the response should determine whether or not the truth of God should be applied, and they refused to compromise. They preferred to make a radical break with 1,500 years of history and culture if necessary rather than to break with the New Testament.”
