The worldwide Unity is also called as Moravian Church. Thus it reminds of the beginnings of the church in Moravia.

It is divided into 25 provinces, which are organizationally and financially quite independent. Each province has a given democratic-synodal constitution (Ground of the Unity or Church Order). The synod elects the church leadership of the province as well as the bishops, who, however, fulfill a purely spiritual office. The provinces have memberships ranging from 1,000 to 250,000 and thus vary in size. In some regions the Moravian Church is a majority church, in many regions a small church alongside others.

In addition to the Unity provinces, there are Mission provinces. These are provinces on the way to independence. They have their own synod and church leadership, but receive financial and personnel support from other provinces.

The mission areas is a preliminary stage of the mission province. Here there are no structures of its own yet, but the work is organized and managed by another province.
