“In joining the YMCA as a member a person accepts or endorses the general objectives and principles of the organization. He is not simply paying for something he receives, such as when buying things being sold to the public at a store. (Compare 1 Corinthians 8:10; 10:25.) Nor is his membership merely an entry pass, as when a person buys a theater ticket. Membership means that one has become an integral part of this organization founded with definite religious objectives, including the promotion of interfaith. Hence, for one of Jehovah’s Witnesses to become a member of such a so-called “Christian” association would amount to apostasy. Some individuals have on occasion not become members but have paid a onetime admission fee, viewing this as simply paying for a commercial service available. Even in this regard it is wise to consider whether this course will adversely affect the consciences of others. —1 Cor. 8:11-13.” Watchtower 1979 January 1st.
