Who authored the Belgic Confession as a response to King Philip II's oppression?

The Belgic Confession was authored by Guido de Bres as a direct response to the persecution faced by Reformed Christians under King Philip II of Spain during the 16th century. Living in a time when Protestant reformers were being oppressed, de Bres sought to articulate a clear statement of faith that would affirm the beliefs and practices of Reformed theology.

Guido de Bres wrote this confession in 1561, and it served to unify Reformed Christians and provide them with a document that could be used in the face of persecution. It outlines essential doctrines of the Christian faith, such as the nature of God, the role of scripture, and the significance of the sacraments, thus reinforcing the community's identity amid adversity.

Contextually, John Hus and John Wycliffe were earlier reformers who faced different issues in their respective times and were not directly involved with the events surrounding the Belgic Confession. Zacharias Ursinus, while an important Reformed theologian and a contributor to the Heidelberg Catechism, was not the author of the Belgic Confession. Hence, Guido de Bres stands as the central figure in relation to this historical document and the context of oppression under King Philip II.
