The church at Londrina was a neo-Pentecostal church which came into contact with Reformed doctrine and practice some years ago. They engaged in a multi-year process of studying all three of the Forms of Unity, as well as the Church Order of Dort. Elders were trained and preparations made to establish a church council. The congregation also held a special service where they officially adopted the Three Forms of Unity and confessional membership. The missionaries have had the privilege of serving and contributing to the process of reformation in this church.
