Church membership is a very open and informal inclusion of all who profess Christian faith and choose to declare this as their regular "home" church. In addition to an active listing in our directory of members to receive information about church life, this distinction is helpful for determining status regarding provisions for use of facilities, weddings, care and accountability, as well as other church member benefits. Corporation Membership. Columbia Community Church, Inc, is a registered corporation in the state of Washington that functions in compliance with laws governing non-profit tax status and the holding of real estate. For this reason, the corporation by-laws stipulate requirements for the conducting of business meetings and membership eligibility for voting privileges.
