Liberty is the state of being free within society from oppressive restrictions imposed by authority on one's way of life, behavior, or political views. The concept of liberty can have different meanings depending on context. In the Constitutional law of the United States, Ordered liberty means creating a balanced society where individuals have the freedom to act without unnecessary interference and access to opportunities and resources to pursue their goals, all within a fair legal system. In Christian theology, liberty is freedom from the effects of "sin, spiritual servitude, [or] worldly ties".
