The New Testament uses a number of military metaphors in discussing Christianity, especially in the Pauline epistles.
In Philippians 2:25 and Philemon 1:2, Paul describes fellow Christians as "fellow soldiers" (in Greek, συστρατιώτῃ, sustratiōtē). The image of a soldier is also used in 2 Timothy 2:3–4 as a metaphor for courage, loyalty and dedication; this is followed by the metaphor of an athlete, emphasising hard work. In 1 Corinthians 9:7, this image is used in a discussion of church workers receiving payment, with a metaphorical reference to a soldier's rations and expenses.
