Missionary congregations are religious groups dedicated to spreading their faith and serving communities, often in different countries or regions. They focus on evangelism, education, and humanitarian efforts, aiming to share their beliefs while addressing social issues like poverty and health care. These congregations are typically part of larger religious organizations, such as the Catholic Church or various Protestant denominations. Members often engage in long-term missions, establishing schools, clinics, and churches to support local populations and foster spiritual growth.
