Final answer:
True, another person named Matthias was appointed to replace Judas Iscariot as an apostle, according to Acts 1:15-26 in the New Testament.
Step-by-step explanation:
The statement that another person was appointed to replace Judas Iscariot as an apostle is true. After Judas Iscariot betrayed Jesus and subsequently died, the remaining apostles sought to find a replacement to maintain the number of twelve apostles, which was significant in their ministry. In the Acts of the Apostles, specifically Acts 1:15-26, the apostles cast lots to select between two men, Joseph called Barsabbas and Matthias. Matthias was chosen and became the twelfth apostle. This event highlights the early Christian community's desire to preserve the apostolic tradition, as the original twelve were chosen by Jesus.
It is important to understand that an apostle in the context of early Christianity was regarded as 'one sent' or 'a messenger', specifically those sent by Christ to spread his teachings. Therefore, the appointment of Matthias was seen as following the will of Jesus and ensuring the continuity of His mission.
