Ecclesiastical Ordinances
The Ecclesiastical Ordinances were the foundational laws introduced by John Calvin in Geneva in 1541 to organize the structure and discipline of the Reformed church. This had been requested by the Genevan authorities after he had been called back from exile, and were strongly influenced by his stay in Martin Bucer's Strasbourg.
