A Brief Declaration and Vindication of the Doctrine of the Trinity

A compact but formidable defense of Trinitarian orthodoxy against the Socinian and Quaker denials of Owen's day. Owen systematically establishes from Scripture that the Father, Son, and Holy Spirit are each fully God and one in essence — then turns to the person of Christ (truly God and truly man in one person) and the satisfaction of Christ (penal substitution as the only ground of forgiveness). Dense with biblical proof texts and surgical rebuttals of Socinian sophistry, this 1669 treatise remains one of the clearest Reformed expositions of the foundational doctrines of Christianity.
