on, not made, nor begotten, but proceeding."

_I answer that,_ The procession of love in God ought not to be called
generation. In evidence whereof we must consider that the intellect
and the will differ in this respect, that the intellect is made actual
by the object understood residing according to its own likeness in the
intellect; whereas the will is made actual, not by any similitude of
the object willed within it, but by its having a certain inclination
to the thing willed. Thus the procession of the intellect is by way of
similitude, and is called generation, because every generator begets
its own like; whereas the procession of the will is not by way of
similitude, but rather by way of impulse and movement towards an
object.

So what proceeds in God by way of love, does not proceed as begotten,
or as son, but proceeds rather as spirit; which name expresses a
certain vital movement and impulse, accordingly as anyone is described
as moved or impelled by love to perform an action.

Reply Obj. 1: All that exists in God is one with the divine nature.
Hence the proper notion of this or that procession, by which one
procession is distinguished from another, cannot be on the part of
this unity: but the proper notion of this or that procession must be
taken from the order of one procession to another; which order is
derived from the nature of the will and intellect. Hence, each
procession in God takes its name from the proper notion of will and
intellect; the name being imposed to signify what its nature really
is; and so it is that the Person proceeding as love receives the
divine nature, but is not said to be born.

Reply Obj. 2: Likeness belongs in a different way to the word and to
love. It belongs to the word as being the likeness of the object
understood, as the thing generated is the likeness of the generator;
but it belongs to love, not as though love itself were a likeness,
but because likeness is the principle of loving. Thus it does not
follow that love is begotten, but that the one begotten is the
principle of love.

Reply Obj. 3: We can name God only from creatures (Q. 13, A. 1). As
in creatures generation is the only principle of communication of
nature, procession in God has no proper or special name, except that
of generation. Hence the procession which is not generation has
remained without a special name; but it can be called spiration, as
it is the procession of the Spirit.
