FIFTH ARTICLE [I, Q. 27, Art. 5]

Whether There Are More Than Two Processions in God?

Objection 1: It would seem that there are more than two processions

in God. As knowledge and will are attributed to God, so is power.

Therefore, if two processions exist in God, of intellect and will,

it seems that there must also be a third procession of power.

Obj. 2: Further, goodness seems to be the greatest principle of

procession, since goodness is diffusive of itself. Therefore there

must be a procession of goodness in God.

Obj. 3: Further, in God there is greater power of fecundity than

in us. But in us there is not only one procession of the word, but

there are many: for in us from one word proceeds another; and also

from one love proceeds another. Therefore in God there are more

than two processions.

_On the contrary,_ In God there are not more than two who

proceed--the Son and the Holy Ghost. Therefore there are in Him

but two processions.

_I answer that,_ The divine processions can be derived only from

the actions which remain within the agent. In a nature which is

intellectual, and in the divine nature these actions are two, the

acts of intelligence and of will. The act of sensation, which also

appears to be an operation within the agent, takes place outside the

intellectual nature, nor can it be reckoned as wholly removed from

the sphere of external actions; for the act of sensation is perfected

by the action of the sensible object upon sense. It follows that no

other procession is possible in God but the procession of the Word,

and of Love.

Reply Obj. 1: Power is the principle whereby one thing acts on

another. Hence it is that external action points to power. Thus the

divine power does not imply the procession of a divine person; but

is indicated by the procession therefrom of creatures.

Reply Obj. 2: As Boethius says (De Hebdom.), goodness belongs to

the essence and not to the operation, unless considered as the

object of the will.

Thus, as the divine processions must be denominated from certain

actions; no other processions can be understood in God according to

goodness and the like attributes except those of the Word and of love,

according as God understands and loves His own essence, truth and

goodness.

Reply Obj. 3: As above explained (Q. 14, A. 5; Q. 19, A. 5), God

understands all things by one simple act; and by one act also He

wills all things. Hence there cannot exist in Him a procession of

Word from Word, nor of Love from Love: for there is in Him only one

perfect Word, and one perfect Love; thereby being manifested His

perfect fecundity.
