Alonzo Trévier Jones (1859–1923) spoke before a United States Congressional subcommittee in 1889, to oppose the Breckinridge Bill, which sought to compel Sunday observance in the District of Columbia. He soon became a world-famous writer and speaker for religious liberty. He served as co-editor of The American Sentinel, a public magazine defending the principles of freedom in the United States.

His desire was to awaken more interest in the study of the Constitution and the Bill of Rights, which would clarify the understanding of men’s liberty of conscience. This book will help each reader to see the relation that should exist between civil government and religion, according to the words of Christ and the American Constitution.
