Definition: The word "clts9" refers to a small group of Christians who gather for spiritual worship and prayer meetings in Jerusalem, often referred to as the "Big Four." They practice a form of Christian baptism known as the "Clts9," which involves immersion or being submerged in water after baptism. The word "clts9" is part of a larger group called the "Seven Churches." This group was initially founded by Paul the Apostle and later spread across various parts of the world, including New York City, London, Paris, and Rome.
