Hendrik de Cock

Hendrik de Cock (12 April 1801 – 14 November 1842) was a Dutch minister responsible for the 1834–35 Dutch Reformed Church split due to his incarceration and suspension from office for his Calvinist convictions.

Hendrik de Cock protested against the perceived theological liberalism in the Netherlands government-controlled Dutch Reformed Church in the 19th century. This protest led to the Secession (Afscheiding) of 1834. He is sometimes called the father of the Secession of 1834.
