The Christian Apostles were a group of twelve followers chosen by Jesus Christ to spread his teachings and establish the early Christian Church. They played a crucial role in sharing the message of Christianity after Jesus' death and resurrection, often traveling to different regions to preach and convert others. Each Apostle had unique characteristics and backgrounds, with notable figures including Peter, who is often considered the leader, and John, known for his close relationship with Jesus. The Apostles' teachings and writings form a significant part of the New Testament, influencing Christian beliefs and practices throughout history.
