Deity, Immanence, Love

Kant does not explicitly address, and three centuries later it seems to remain unrecognized, Spinoza's radical departure from the premises of Medieval Theology.  The departure does not emerge in some intricate proof, but is plainly asserted at the outset of his doctrine--the thesis of an immanent deity, that has more in common with the Seminal Logos of some Stoics, than with the the Abrahamic deity of Medieval Theology and thereafter.  However, Spinoza himself, perhaps deliberately, out of prudence, contributes to the subsequent obscuration of his heterodoxy, by not explicitly developing what is entailed in the concept of an immanent deity--that its creatures are parts of it.  Accordingly, the Intuition of the deity, by a creature, consists in the creature's awareness of that immanence, i. e. that it is a part of the deity, i. e. it is not a mere location of a passing visitation by the deity.  Instead, Spinoza compounds the obscuration, again perhaps deliberately, by further characterizing Intuition as constituted by a "love" of the deity.  For, he defines 'love' as "pleasure, accompanied by the idea of an external cause", which contradicts the concept of a deity as immanent in its lover.  So, centuries later, the concept of a Human as organically a part of a whole, whether of Substance/God/Nature, or of a Species, remains undeveloped.
