"""
Output:

It is unclear who wrote the letter, as some scholars believe it was written by James, the brother of Jesus, while others believe it was written by a different James who was also a leader in the early Christian church. 

The letter was likely written to encourage and instruct fellow believers in the Christian faith. The author identifies himself as a servant of God and Jesus, emphasizing his submission to them and his desire to serve them. He also uses the greeting to affirm his belief in the divinity of Jesus.
