The correct option for the statement, "This man is that power of God which is called Great," referring to Simon the magician, is C. Samaria. Detailed Explanation:

1. Context of the Statement:
2. The statement about Simon the magician is found in the Book of Acts in the New Testament, specifically Acts 8:9-10. Simon was a sorcerer in Samaria who amazed the people with his magic and claimed to be someone great. The people of Samaria referred to him as "the great power of God" because of the wonders he performed.
3. Historical Background:
4. Simon the magician lived during the early days of the Christian church, shortly after the ascension of Jesus. The apostles, particularly Philip, went to Samaria to preach the Gospel. Simon's actions and the subsequent conversion of many Samaritans are significant in the narrative of the spread of Christianity beyond Jewish communities.
5. Why Option C is Correct:
6. The phrase "this man is that power of God which is called Great" directly relates to Simon's reputation in Samaria. The people were impressed by his magical abilities and attributed divine power to him. This is a key point in the story, as it sets the stage for the contrast between Simon's sorcery and the true power of God demonstrated through the apostles.

Why the Other Options are Incorrect:

• A. Macedonia:
• Macedonia is not the location associated with Simon the magician. The early missionary journeys of Paul took him to Macedonia, but Simon's story is specifically tied to Samaria. Therefore, this option is incorrect.
• B. Jerusalem:
• While Jerusalem is a central location in the early church and the site of many significant events, Simon the magician's activities and the statement in question are not linked to Jerusalem. The apostles did preach in Jerusalem, but Simon's influence and the people's reaction to him occurred in Samaria.
• D. Ephesus:
• Ephesus is another important city in the New Testament, known for Paul's ministry and the establishment of the church there. However, Simon the magician's story does not take place in Ephesus. This option is also incorrect.

Summary of Key Points:

• Simon the magician was a sorcerer in Samaria who claimed to be "the great power of God."
• The statement about Simon is found in Acts 8:9-10, highlighting his influence in Samaria.
• The other options (Macedonia, Jerusalem, Ephesus) do not relate to Simon's story or the specific statement made about him.

Revision Summary:

• Simon the magician is associated with Samaria, where he was called "the great power of God."
• The reference to Simon is found in Acts 8:9-10.
• The other options (Macedonia, Jerusalem, Ephesus) are not relevant to Simon's narrative.
• Understanding the context of Simon's story is crucial for grasping the early spread of Christianity.
