The activities described in section 3(r) are included in an enterprise only when they are performed for a “business” purpose. Activities of eleemosynary, religious, or educational organization may be performed for a business purpose. Thus, where such organizations engage in ordinary commercial activities, such as operating a printing and publishing plant, the business activities will be treated under the Act the same as when they are performed by the ordinary business enterprise. (See Mitchell v. Pilgrims Holiness Church Corp., 210 F. 2d 879 (CA-7); cert. den. 347 U.S. 1013.) However, the nonprofit educational, religious, and eleemosynary activities will not be included in the enterprise unless they are of the types which the last sentence of section 3(r), as amended in 1966, declares shall be deemed to be performed for a business purpose. Such activities were not regarded as performed for a business purpose under the prior Act and are not so considered under the Act as it was amended in 1966 except for those activities listed in the last sentence of amended section 3(r). (See § 779.21.)
