the opinion of some. While some would argue this is appropriate, J. Richard Middleton argued for a reassessment of the Biblical sources to better understand the original meaning before taking it out of context and applying it. Instead of various extra-biblical interpretations, he pushed for a royal-functional understanding, in which "the imago Dei designates the royal office or calling of human beings as God's representatives or agents in the world." Ecological impact With the rise of contemporary ecological concerns the functional interpretation of the image of God has grown in popularity. Some modern theologians are arguing for proper religious care of the earth based on the functional interpretation of the image of god as caregiver over created order. Thus, exerting dominion over creation is an imperative for responsible ecological action. Critique One of the critique of the functional interpretation of the imago dei is that some formulations might convey a negative message that it conveys about persons with disabilities. Within the functional view, it is often thought that disabilities which interfere with one's capacity to "rule," whether physical, intellectual, or psychological, are a distortion of the image of God. This formulation of the functional view isolates and excludes those with disabilities, and some theologians even use it to go so far as to state that animals more fully display the Image of God than people with profound disabilities. At the same time, however, the substantive view has been criticized for exactly this issue. Imago dei and human rights The imago dei concept had a very strong influence on the creation of human rights. Puritan origin of human rights Glen Stassen argues that both the concept and the term human rights originated more than a half-century before the Enlightenment thinkers like John Locke. Imago dei in reference to religious liberty of all persons was used by the free churches (Dissenters) at the time of the Puritan Revolution as an affirmation of the religious liberty of all persons. The concept was based not only on natural reason but also on the Christian struggle for liberty, justice, and peace for all. The background of this struggle lay in the time of the English Revolution. The king had been alienating many Christians by favoring some churches over others. According to the scholar of Puritan literature William Haller, "the task of turning the statement of the law of nature into ringing declaration of the rights
