(2) Except as provided in paragraph (c)(3) of this section, service performed by a minister in the exercise of his ministry includes the ministration of sacerdotal functions and the conduct of religious worship, and the control, conduct, and maintenance of religious organizations (including the religious boards, societies, and other integral agencies of such organizations), under the authority of a religious body constituting a church or church denomination. The following rules are applicable in determining whether services performed by a minister are performed in the exercise of his ministry:(i) Whether service performed by a minister constitutes the conduct of religious worship or the ministration of sacerdotal functions depends on the tenets and practices of the particular religious body constituting his church or church denomination.(ii) Service performed by a minister in the control, conduct, and maintenance of a religious organization relates to directing, managing, or promoting the activities of such organization. Any religious organization is deemed to be under the authority of a religious body constituting a church or church denomination if it is organized and dedicated to carrying out the tenets and principles of a faith in accordance with either the requirements or sanctions governing the creation of institutions of the faith. The term "religious organization" has the same meaning and application as is given to the term for income tax purposes.(iii) If a minister is performing service in the conduct of religious worship or the ministration of sacerdotal functions, such service is in the exercise of his ministry whether or not it is performed for a religious organization. The application of this rule may be illustrated by the following example: Example. M, a duly ordained minister, is engaged to perform service as chaplain at N University. M devotes his entire time to performing his duties as chaplain which include the conduct of religious worship, offering spiritual counsel to the university students, and teaching a class in religion. M is performing service in the exercise of his ministry.
(iv) If a minister is performing service for an organization which is operated as an integral agency of a religious organization under the authority of a religious body constituting a church or church denomination, all service performed by the minister in the conduct of religious worship, in the ministration of sacerdotal functions, or in the control, conduct, and maintenance of such organization (see subparagraph (2)(ii) of this paragraph) is in the exercise of his ministry. The application of this rule may be illustrated by the following example: Example. M, a duly ordained minister, is engaged by the N Religious Board to serve as director of one of its departments. He performs no other service. The N Religious Board is an integral agency of O, a religious organization operating under the authority of a religious body constituting a church denomination. M is performing service in the exercise of his ministry.
(v) If a minister, pursuant to an assignment or designation by a religious body constituting his church, performs service for an organization which is neither a religious organization nor operated as an integral agency of a religious organization, all service performed by him, even though such service may not involve the conduct of religious worship or the ministration of sacerdotal functions, is in the exercise of his ministry. The application of this rule may be illustrated by the following example: Example. M, a duly ordained minister, is assigned by X, the religious body constituting his church, to perform advisory service to Y Company in connection with the publication of a book dealing with the history of M's church denomination. Y is neither a religious organization nor operated as an integral agency of a religious organization. M performs no other service for X or Y. M is performing service in the exercise of his ministry.
