"초대 교회" refers to the early Christian church that emerged after the death and resurrection of 예수 그리스도. This period, roughly from 30 AD to 100 AD, was characterized by small, close-knit communities of believers who gathered for worship, prayer, and the sharing of teachings. The early church focused on spreading the message of Christianity and establishing a foundation for future growth. During this time, the followers of 예수 faced persecution and challenges, yet they remained committed to their faith. The teachings of the apostles, such as 베드로 and 바울, played a crucial role in shaping the beliefs and practices of the early church, which laid the groundwork for the development of organized Christianity.
