John Chrysostom uses military metaphors from Romans to help believers understand their relationship with God and engage in spiritual warfare. He compares circumcision and baptism to expand their meaning. By likening body parts to weapons, he teaches that individuals choose whether to serve truth or sin. In this analogy, God is the commander, and believers are soldiers fighting sin, stressing obedience and trust. Chrysostom urges obedience to God akin to soldiers obeying their leader, connecting it with faith-based trust. Military imagery encourages active participation in battling sin, emphasising commitment beyond formal duties. Overall, Chrysostom’s metaphors aim to deepen the congregation’s faith through active engagement and obedience.
