Final answer:
Philip followed the guidance of the angel of the Lord to minister to the Ethiopian eunuch, an event detailed in the New Testament that contributed to the spread of Christianity. The correct answer is option : angel of the Lord.
Step-by-step explanation:
Philip left the great revival in Samaria to minister to the Ethiopian eunuch in obedience to the direction of the angel of the Lord. This is found in the Acts of the Apostles in the New Testament, which details how the apostles and early Christians spread the teachings of Jesus Christ. In this specific instance, Philip is guided by an angel to leave Samaria and travel toward Gaza, which is where he encounters the Ethiopian official who is reading the book of Isaiah. The Holy Spirit then tells Philip to approach the chariot, leading to the pivotal moment where the Ethiopian eunuch learns about Jesus from Philip and decides to be baptized as a Christian.
