In Brazil and around the world


This page gives a brief overview of the Mathenys’ work in Brazil, with publications and through the Internet.


Randal participated in his first evangelistic door-to-door campaign as a high-school student. He made the decision to be a missionary during his first semester at college, in 1975. He has been involved in foreign missions ever since.

He and Vicki have lived continuously in Brazil since 1984 as missionaries inserted into the culture who speak the language of the people. His efforts have included:

  • Personal evangelism and church planting.
  • Christian training in personal holiness and service.
  • Public teaching and speaking in local churches and brotherhood events.
  • Portuguese-language publications, including Edificação magazine, tracts, booklets, and books.
  • Involvement in Christian youth camp, Christian child care, preacher training programs and ministry preparation.
  • Online evangelism and edification through various websites, email lists and groups, social media, and intensive personal contact with Portuguese speakers.

Today, the Mathenys devote most of their time to evangelism, church planting, servant training, and writing and publishing.


Since 1995 the Mathenys have been located in the city of São José dos Campos, Brazil, between São Paulo and Rio de Janeiro, but their ministry reaches around the world through the teaching done in print and on the Internet.
