The Belgic Confession, written in 1561, owes its origin to the need for a clear and comprehensive statement of Reformed faith during the time of the Spanish inquisition in the Lowlands.
The Heidelberg Catechism, written in 1563, originated in one of the few pockets of Calvinistic faith in the Lutheran and Catholic territories of Germany.
In 1677, Reformed Baptists anonymously published the Second London Confession of Faith. This was a confession based upon the Westminster Confession of Faith and the Savoy Declaration.
