According to the stablisment clause, how would a historical societys posting of the Ten Commandments along with the history of religion and it's belief and practiced be viewed?

The Establishment Clause prohibits the government to establish an official religion, to favor one religion over another, or to favor religion or non-religion over the other. For this reason, religion classes in public schools, for example, would go against this clause because they are considered religious endoctrination in places supported by the government.

However, if a historical society posts about the Ten Commandments along with the history of religion and its beliefs, this practice would not go against the Establishment Clause because its purpose would be purely educational, and secular (not connected with religious or spiritual matters) in motivation.
