There are two completely different churches pictured in the New Testament.
One, the true Ecclesia Jesus built, is described as the bride of Christ, forsaking involvements with this world and its customs in order to be pure when He comes for her.
But, throughout the New Testament, it was prophesied that false teachers would creep in and try to gain control of this small flock . True Christ followers would have to flee from many of their original congregations to continue to obey God. They would, therefore, be a “little flock,” (Luke 12:32) often scattered, never having political power/influence of any kind in this world.
The world has kept little track of this small, scattered, persecuted Ecclesia that Christ promised that He would never leave or forsake it and that “the gates of hell [the grave] shall not prevail against it” (Matt. 16:18).
Though it has periodically had to scatter for its life (Acts 8:1; Dan. 12:7), Christ has faithfully kept His promise to remain with it, empowering and strengthening it through His Spirit. Despite continual persecution—even during periods of great martyrdom by the large popular churches that have always sought to destroy it—a remnant has always remained throughout the last nearly 2,000 years. It has continued to “keep the commandments of God, and the faith of Jesus” (Rev. 14:12).
Let us be mindful at all times, to KNOW the difference between the Two (2)
