All who are led by God’s Spirit are God’s sons and daughters. 15 You didn’t receive a spirit of slavery to lead you back again into fear, but you received a Spirit that shows you are adopted as his children. With this Spirit, we cry, “ Abba, Father. ” 16 The same Spirit agrees with our spirit, that we are God’s children. 17 But if we are children, we are also heirs. We are God’s heirs and fellow heirs with Christ, if we really suffer with him so that we can also be glorified with him.
In this second volume of "Readings in the History of Christian Theology," William C. Placher begins with a decisive transition, the Reformation of the sixteenth century, and opens with an excerpt from Martin Luther's "The Freedom of a Christian." From the sixteenth century into the twentieth, he presents significant selections from works of the principal Protestant and Catholic thinkers, including present-day writers such as Gustavo Gutierrez and Rosemary Radford Ruether.
