Yes. Classical Historian materials are not religious materials, and our products do not promote one religion over another. Our materials are approved for use in public schools, including public charter schools.
However, we agree that the United States of America is a cultural and historical descendant of the forefathers of western civilization: the Judeo-Chrisitian and Greco-Roman cultures. And, the Classical Historian also holds that the best of these societies contribute to what is ideal in human affairs: natural law, the rule of law, value of all individual life regardless of influence, power, or age, the sanctity of life, the idea that the republican form of government is better than tyranny, and Constitutional liberty as described in the U.S. Constitution.
Teaching with the Take a Stand! series helps me get to know my children and students better and it helps them how to think critically, form historical judgement, and express themselves in speech and in writing.
