Our Team in the Field

Elias Barbosa da Silva
Reformed Education Worker
As a Reformed Education Worker I am serving the Reformed Churches of Brazil strengthening the Christian worldview for parents and teachers. Basically I present and promote to them a Reformed Christian worldview that clearly teaches that all of life – in family, church, and school – should be integrated together, serving and glorifying God. I organize teaching moments for teachers and church members with guest speakers or sharing a lecture myself on various related topics. I make contacts with local champions, Christian teachers and school boards making myself available to help them in what they need. I search for, develop, and deliver appropriate programs and educational resources for families, teachers, schoolboards and office-bearers, which enable them to effectively model and teach their faith to the next generation. I record and publish Bible stories in the Old and New Testaments, which will be used, for example, as part of a program for teaching Sunday Schools.

Jonathan Chase
Pastor Jonathan Chase was called recently to serve as a missionary alongside Pastor Witteveen. He and his family have just arrived in Brazil in the summer of 2021. His focus will be teaching in the seminary for the preparation of future pastors and missionaries, continuing with outreach efforts, and working alongside the Reformed Churches of Brazil for their strengthening and edification.
Jim Witteveen
Pr. Jim Witteveen accepted Aldergrove’s call to serve as missionary in Brazil in August of 2015. In 2017 he moved to Brazil to take up his task, which includes preparing men to become ministers of the Word at the John Calvin Institute, leadership training, conference speaking, evangelistic work, providing support to local instituted congregations and mission congregations, and regular preaching of the Word. Since August 2020 he has been working from his home base in Abbotsford B.C., where he continues to serve as a director of the John Calvin Institute, teaching courses online, preparing material for training of officebearers, and producing evangelistic resources.
