essence of a triangle - in fact, that the necessity of a triangle's essence
and nature, in so far as they are conceived of as eternal verities, depends
solely on the necessity of the Divine nature and intellect, we then style
God's will or decree, that which before we styled His intellect. (57)
Wherefore we make one and the same affirmation concerning God when we say
that He has from eternity decreed that three angles of a triangle are equal
to two right angles, as when we say that He has understood it.

(58) Hence the affirmations and the negations of God always involve
necessity or truth; so that, for example, if God said to Adam that He did
not wish him to eat of the tree of knowledge of good and evil, it would have
involved a contradiction that Adam should have been able to eat of it, and
would therefore have been impossible that he should have so eaten, for the
Divine command would have involved an eternal necessity and truth. (59) But
since Scripture nevertheless narrates that God did give this command to
Adam, and yet that none the less Adam ate of the tree, we must perforce say
that God revealed to Adam the evil which would surely follow if he should
eat of the tree, but did not disclose that such evil would of necessity
come to pass. (60) Thus it was that Adam took the revelation to be not an
eternal and necessary truth, but a law - that is, an ordinance followed by
gain or loss, not depending necessarily on the nature of the act performed,
but solely on the will and absolute power of some potentate, so that the
revelation in question was solely in relation to Adam, and solely through
his lack of knowledge a law, and God was, as it were, a lawgiver and
potentate. (61) From the same cause, namely, from lack of knowledge, the
Decalogue in relation to the Hebrews was a law, for since they knew not the
existence of God as an eternal truth, they must have taken as a law that
which was revealed to them in the Decalogue, namely, that God exists, and
that God only should be worshipped. (62) But if God had spoken to them
without the intervention of any bodily means, immediately they would have
