4. Let us, then, continue our inquiry now in order. For under the second head in that division the question occurred, whether the creature was formed for that work only, wherein God, in such way as He then judged it to be fitting, might be manifested to human sight; or whether angels, who already existed, were so sent as to speak in the person of God, assuming a corporeal appearance from the corporeal creature for the purpose of their ministry; or else changing and turning their own body itself, to which they are not subject, but govern it as subject to themselves, into whatever forms they would, that were appropriate and fit for their actions, according to the power given to them by the Creator. And when this part of the question shall have been investigated, so far as God permit, then, lastly, we shall have to see to that question with which we started, viz., whether the Son and the Holy Spirit were also “sent” before; and if it be so, then what difference there is between that sending and the one of which we read in the Gospel; or whether neither of them were sent, except when either the Son was made of the Virgin Mary, or when the Holy Spirit appeared in a visible form, whether as a dove or in tongues of fire.
