The Nederduitse Gereformeerde Kerk initiated mission work among Portuguese-speaking refugees from Angola and Mozambique in South Africa.
The work was led by Reverend (later, Doctor) Arnoldus Petrus Pienaar, Rev.
Some members began returning to Portugal, their land of origin, but at that time, no Reformed Church had been established there.
These efforts led to the formation of two autonomous congregations, known as the Reformed Church in Portugal.
In 2005, Pastor Hermanus (Manie) Taute arrived to lead the Reformed Movement in Portugal.
