There is in Orthodox Tradition a sense that correct belief leads to a correct way of life or that correct thinking leads to correct living. Conversely, a wrong way of living – sinning – can often be traced to a wrong set of beliefs. Confession and repentance in this thinking are efforts to get to the root cause of one’s sinful behavior and to aim to correct the thinking or beliefs that have allowed one to choose wrong behavior. Correct theology then is not just a set of intellectual premises which we affirm through rational logic, but rather is the healing antidote to what ails humanity and leads us astray from God. Correct theology is both the light that shows us the right path and the proper path itself. As Jesus Himself said:
“I am the way, and the truth, and the life; no one comes to the Father, but by me.” (John 14:6)
“I am the light of the world; he who follows me will not walk in darkness, but will have the light of life.” (John 8:12)
Protestant Theologian Jeremy S. Begbie writes:
By “the gospel” I mean the announcement that in the life, death, and resurrection of Jesus, the Triune Creator, the God of Israel, has acted decisively to reconcile the world to himself. Here is theology’s raison d’etre and its lodestar – theology is not free-floating speculation, but it is disciplined by this gospel and seeks to interpret the whole of reality from this center. Just because it is so motivated, the theologian is ultimately responsible to a living God: the God of the gospel is not an inert presence but personally active, continuously at work to transform his creatures and his creation. Hence learning about God is undertaken in the context of learning from God, as God relates to us and we to God. This means, in turn, that theology is inseparable (though distinct) from prayer and worship – thinking appropriately about God means regularly engaging with God. . . . Precisely because it relates to the whole of us and concerns the energetic, life-transforming God of the gospel, theology has a practical orientation.
One of the best ways to express this is to speak of theology fostering wisdom. In the so-called Wisdom literature of the Bible (for example, the book of Proverbs), gaining wisdom concerns much more than amassing data for the mind’s scrutiny. It is practically geared. To be wise means being able to discern what is going on in specific, down-to-earth situations and to judge what it is right to say and do in those situations in a way that is faithful and true to God. We become wise in order to live well. As “lived knowledge,” wisdom is directed toward a lifestyle thoroughly “in tune” with God – godly living – that resonates aptly with the Creator’s intentions for us and his world.
(Resounding Truth, p. 20)
Let the word of Christ dwell in you richly, teach and admonish one another in all wisdom, and sing psalms and hymns and spiritual songs with thankfulness in your hearts to God. And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. (Colossians 3:16-17)
