OF OPEN QUESTIONS
Those questions in the domain of Christian doctrine may be termed open questions which Scripture answers either not at all or not clearly. Since neither an individual nor the Church as a whole is permitted to develop or augment the Christian doctrine, but are rather ordered and commanded by God to continue in the doctrine of the apostles, 2 Thess. 2:15; Acts 2:42, open questions must remain open questions. — Not to be included in the number of open questions are the following: the doctrine of the Church and the Ministry, of Sunday, of Chiliasm, and of Antichrist, these doctrines being clearly defined in Scripture.
