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.
"Trinity 101" offers readers a basic approach to the Trinity as history portrays it, as a doctrinal concept, and how it is revealed in the Scripture. This is highly useful to those seeking a starting point of Catholic theological study of the Trinity, from high school age onwards; and also to educated Catholic adults who are drawn to this topic. James Papandrea writes in an engaging and accessible style on the theological background of the Trinity.
