De sarcienda ecclesiae concordia

De sarcienda ecclesiae concordia (On Repairing the Harmony of the Church) is a work by Desiderius Erasmus published in 1533. This treatise was written during a period of intense religious division, following the Protestant Reformation. Erasmus, a humanist scholar, advocated for reconciliation and reform within the Christian church.123

In De sarcienda ecclesiae concordia, Erasmus suggested that differences on crucial doctrines, such as justification, might be resolved by considering a "duplex justitia" (double justice), though he did not elaborate on its meaning. His work aimed to bridge the divide between Catholic and Protestant factions, reflecting his broader efforts to promote peace and understanding within Christendom. He believed that a true understanding of the Gospel and a focus on core Christian principles could help heal the schisms that had emerged.12
