In 1801, the Board of Directors of the South African Society for the Advancement of Christ's Kingdom acquired a property in Long Street, Cape Town, for 50,000 guilders. The existing buildings were demolished and the Sendinggestig built. It was inaugurated on 15 March 1804 by Rev. J.P. Sеrumer of the Dutch Reformed Church's Groote Kerk, Cape Town congregation. The Sendinggestig was not originally used for worship services. Instead people went there for prayer meetings, Bible studies or other religious and literacy classes. For this reason it was not called a church, but a gestig or oefeninghuis which is the Dutch equivalent of an American meeting house. Twenty years later it did become a fully-fledged church. This congregation included the poor, Khoekhoen or Khoikhoi and Slaves who converted to Christianity.
