Christian groups are communities of believers who follow the teachings of Jesus Christ and the principles of the Bible. These groups can vary widely in beliefs, practices, and traditions, ranging from large denominations like Catholicism and Protestantism to smaller, independent congregations. They often gather for worship, prayer, and fellowship, aiming to grow spiritually and support one another. Many Christian groups also engage in outreach and service activities, helping those in need and promoting social justice. They may focus on specific missions, such as youth ministry, education, or humanitarian efforts, reflecting their commitment to living out their faith in practical ways.
