Excerpt from John Mark Hicks blog regarding “Systematic Christian Doctrine”. You can read the entire post here.
Ellen T. Charry has argued that the function of Christian Doctrine is aretegenic, that is, it is “conducive to virtue” or it generates a virtuous life (By the Renewing of Your Minds [Oxford: Oxford University Press, 1977], p. 19). The purpose of Christian doctrine is character formation, spiritual formation. Theology should give the people of God an identity (a sense of calling and status) and equip them with normative ideas and values that shape them into the image of Christ. The function of Christian doctrine is practical—to build a community which images God. Thus, the goal is neither polemical victory (to glory in being “right” on every issue) nor theological ingenuity (to glory in a “new” idea). It is pragmatic. Christian doctrine should serve God’s intent to seek a people that share his values and holiness in communion with him.
Theology is neither metaphysical speculation nor polemical exchange, but the applied story of God toward the goal of character formation—to be formed into the image of Christ. As Paul told Titus, if we will teach Christian doctrine (stress the theology of Titus 3:3-7), then the Christian community will be full of good works (Titus 3:8). This is the kind of “teaching” that is “good and profitable.” A community is shaped by its doctrine; it will become what its doctrine is. Teachers and preachers pay heed. Doctrine must be aretegenic if it is to be biblical.
What theology does Paul have in mind? He summarizes it in Titus 3:3-7. If Titus would have a vibrant community of faith, he should stress this: (1) the triune work of God—the Father who loved us through Jesus the Son and renewed us through the Holy Spirit; (2) our utter fallenness and thus the need for redemption; (3) the divine initiative for our salvation, the motive that moved the divine initiative, and the divine work which accomplished it; (4) the nature and means of our salvation as our redemption is not only forgiveness by the grace of Jesus Christ but transformation by the power of the Spiorit; and (5) the creation of a community of believers with eschatological hope.
Stress these things, Paul told Titus, and the people of God will be dedicated to good works (transformed living in service to others). They will avoid foolish controversies and quarrels about the law (polemics will not be their focus). They will be God’s people who image Christ in a fallen world; they will be a people who live according to the age to come rather than fashioned by this present evil age.
