Some aspects of the Unity movement are denominational, and some are not. For example, there are more than 900 Unity churches and study groups affiliated with Unity's sister organization, the Unity Worldwide Ministries. This is a denominational aspect of Unity. In addition, the Unity Institute at Unity Village trains approximately 60 students every two years to be Unity ministers. This is also denominational. However, the majority of the work done by Unity involves prayer, publishing and education services to people of all faiths. These nondenominational aspects include the prayer ministry, Silent Unity, Daily Word (Unity's nondenominational inspirational monthly magazine), retreats and continuing education classes that are open to everyone and teach Unity principles in nondenominational settings.
