This article considers the first question in the liturgical form for profession of faith used in the Continental tradition, "Do you wholeheartedly believe the doctrine of the Word of God, summarized in the confession and taught here in this Christian church?" It explains that "doctrine" is the teaching of the Lord, and how it is as important as lifestyle.
The author begins by identifying the prevailing problem in the church today, that doctrine seems to be neglected. The "heart vs. head heresy" is cited as the problem. Consequently the author then traces where false doctrine harmed or was a potential harm to the church, and then considers the positive effects of sound doctrine. The author concludes by explaining the link and relationship between theory and practice, or doctrine and life.
