Today is the era of welfare. The desire of social welfare has increased rapidly because of the increase of the average life-span and the rate of the aged people over 65 years old among total population. With this social trend, the necessity of welfare for missionaries for effective missionary work has increased. We can find the biblical foundation for missionary welfare where the Bible mentioned reliefs and welfare in the community of faith. A missionary is a member of the community. Even if a missionary is a servant and instrument of God, he/she is a human being. A missionary has family members. He/she can also get a cultural shock and reverse cultural shock, and an unexpected accident. He/she is aging and shall be retired. He/she, therefore, also needs welfare care for his/her physical, mental, and spiritual health in the community, which can increase the effectiveness in their missional works. There are several dimensions of member cares: 1) Care for physical health, 2) Care for emotional and mental health, 3) Care for retired missionaries. In terms of care for physical health of a missionary, Korean missionary societies are further behind than the International Missionary Societies (ig. SIM, OM, OMF, WEC). They have prepared medical and insurance supporting systems very well. In this respect, Korean church needs to establish this kind of missionary infra. For emotional and mental state, a missionary needs sabbatical year for healing, refreshing and maintaining his/her healthy mental state for effective missional work. For the retired missionaries, a supporting system for housing, foods supply and medical service should be provided. His/her various experiences need to be utilized for developing a strategy and policy for a effective missional work of the future generations. Accordingly, we must prepare a system and policy for missionary member care in order to enhance effective missional works within this welfare and aging times. For this, this study has addressed several dimensions of policy and methodology: For a effective missionary member care, fulfillment of desire for self-realization of missionary, establishment of an appropriate organization and a policy for member care with an effective management for care for crisis/accidental incident, a practical strategy at the denominational level, cooperation for win-win strategy among denominations, sending church and missionary societies should be considered. Missional business strategy and brand standardization for 'missional marketing' have been pointed. First, fulfillment of desire for self-realization. According to A. H. Maslow, the desire of self-realization is the highest desire. A missionary also has this desire. Korean church is lacking of this system for fulfilling the desire of self-realization, especially after a missionary retires. Second, organization and policy for caring member. a Community needs an effective organization for achieving its objective. So is a missionary society. Mission can be effective when members in the community can be managed effectively. Third care for crisis/accidental event. A missionary can also meet crisis/accidental event. Only effective management and care can increase the effectiveness of mission. Four, practice for missionary member care. Missionaries are spiritual soldiers. So they need care and management system and practical strategy at the denominational level. Denomination, sending church and society must cooperate one another for win-win strategy. They need missional business strategy like a business company. Through brand standardization, they must try to increase the value of brand. I wish to call it 'missional marketing'.
