Spinoza's model of God: pantheism or panentheism?

The philosophical God of Spinoza is branded as a pantheistic God so often that, regarding at least Western philosophy and philosophical commentaries, Spinozism seems to be practically synonymous with pantheism. Since the times of German idealism, there have also been attempts at a panentheistic reading, which are still alive to this day. The article analyses both theological models in their core claims to adequately qualify Spinoza's theological system while considering the established levels of philosophical-theological interpretation. By identifying systemic pantheism and essentialist panentheism in his system, it is argued that both accounts or readings of Spinoza's theory might be correct in their own way, provided that the models behind them are correctly applied to their respective levels of thought.
