This study aims to awaken the consciousness of Christians worldwide, called the global church, about the menaces of heresies posed by this present age of globalisation and how to combat them. The age of globalisation is known as the age of information technology, communication systems, transportation networks, and religious marketing. In this age, the world is brought into one tiny unit known as the global village, and the global church cannot pretend to be unaware. Today, practically every aspect of life is affected by globalisation. The globe has successfully become a global village where information and technology are available to everyone every day, hour, minute, and second. The emergence of this trend has increased the number of heretical teachings, both in the church and on social media platforms. This descriptive study relied mainly on secondary data collected from various journals, magazines, books, and websites. Therefore, the paper examines the meaning and conceptions of globalisation, kingdom Christian education, and the global church; the menaces of globalisation on the global church; the historical conception and overview of heresy; how to identify heresies in the church; and recommendations on how to combat heresies.
