Every church wants to grow. Every church wants a healthy congregation growth. Church growth is classified into two types: number and quality. Quantitative growth refers to a significant increase in church membership. Quality growth is characterized by the number of church members who are spiritually mature enough to want to be served as well as serve. The early church grew rapidly. The early church grew numerically as fresh souls joined the Christian fellowship. Moreover, the Early Church had qualitative growth, with every member actively participating in church activities. What prompted the early church's explosive growth? It was communication. The Early Church had good communication among its members. As a result, the Early Church grew in both quantity and quality. This paper will discuss the importance of communication in church growth. This discussion is based on Acts 2:41-47. This article will help church leaders to look inside their churches and learn from the early church about healthy communication within the church, with the anticipation that the experiences of Early Church might be experienced again by churches today.
