Well, I just meant that Spinoza was a Jewish heretic, not a Christian heretic (at least, no more than say, Mohammad), since the discussion was about Christian heresies specifically. The encyclical only discusses pantheism rather than Spinoza---I don't know that pantheism is specifically Spinoza's invention. Of course, no doubt that Spinoza wouldn't be considered a conforming Christian by any Christian church, but not just because he wrote "Deus sive Natura" (the extent to which Spinoza's thought on the relationship between God and creation is incompatible with classical theism is up for debate, it seems to me.
