Does Matthew 16 Support the Doctrine of the Papacy?
Luther's critique is not confined to his contemporary experience of the Papacy, but draws on historical and theological arguments.
According to Calvin the Papacy is totally invalid because in the New Testament there is no injunction given to Peter to find successors in a juridical sense. To keep the unity of the Church, Christ is all we need.
