God

By God, I understand Being absolutely infinite, that is to say, substance constituting of infinite attributes, each one of which expresses eternal and infinite essence.

Explanation. I say absolutely infinite but not infinite in its own kind (in suo genere); for of whatever is infinite only in its own kind (in suo genere), we can deny infinite attributes; but to the essence of that which is absolutely infinite pertains whatever expresses essence and involves no negation.
(Ethics, 1D6)
