We are Arthur and Caitlin Rosa, and we are Career Missionary Associates working in Nova Iguaçu, Brazil. We are on staff at Igreja Castelo do Rei, a new church plant started in 2024 by King’s Castle Brazil. Arthur works with the worship team, while Caitlin works with the media team. We are both an active part of various discipleship ministries, including two small groups: one for kids and one for adults. We desire to see people come to know God for who He truly is.
