All the church's teachings are expressed orally, and the church does not publish doctrine or statements of faith. Workers hold that all church teachings are based solely on the Bible. A catchphrase frequently used to describe the church is: "The church in the home, and the ministry without a home". The church does not own church buildings. These are seen as inconsistent with biblical Christianity and were strongly denounced by early workers. Its ministers do not own homes or draw a salary. The church has upheld these practices since its inception. Notwithstanding this tradition, buildings specially constructed or repurposed for the use of the church do exist, including convention buildings, meeting halls, tents and caravans and portable halls. Real properties are largely held and maintained on behalf of the church by certain members, however in recent years, a Northern Irish investment vehicle has been used to purchase English convention property.
