Under Dutch rule, the building was designated a Protestant place of worship, alongside the Brussels Protestant Church on the /, and the Dutch Church ("Nederlandse gemeente") met in the Temple from 1816 until the Belgian Revolution in 1830. The first Reformed service was held on 1 September 1816, and Hermannus Pauw (born 1770) and Dirk Rijke (1789–1830) served as ministers from 1816–1830. In March 1817, the future King William III was baptised in the Temple. Anglican Reverend Holworthy, chaplain to the British Ambassador, held English-language services in the Temple until 1829.
