A couple of patristic quotes about the descent to
inferus/
ta katôtata:
By ourselves
inferi are not supposed to be a bare cavity, nor some subterranean sewer of the world, but a vast deep space in the interior of the earth, and a concealed recess in its very bowels; inasmuch as we read that Christ in His death spent
three days in the heart of the earth, (Matthew 12:40) that is, in the secret inner recess which is hidden in the earth, and enclosed by the earth, and superimposed on the abysmal depths which lie still lower down. Now although Christ is God, yet, being also man, “
He died according to the Scriptures,” (1 Corinthians 15:3) and “
according to the same Scriptures was buried.” With the same law of His being He fully complied, by remaining in Hades in the form and condition of a dead man; nor did He ascend into the heights of heaven before descending into the lower parts of the earth, that He might there make the patriarchs and prophets partakers of Himself (1 Peter 3:19). (This being the case), you must suppose
inferus to be a subterranean region, and keep at arm’s length those who are too proud to believe that the souls of the faithful deserve a place in the
inferi. These persons, who are “
servants above their Lord, and disciples above their Master” (Matthew 10:24), would no doubt spurn to receive the comfort of the resurrection, if they must expect it in the bosom of Abraham.

A Treatise on the Soul 55
Celsus next addresses to us the following remark: “
You will not, I suppose, say of him, that, after failing to gain over those who were in this world, he went to Hades to gain over those who were there.” But whether he like it or not, we assert that not only while Jesus was in the body did He win over not a few persons merely, but so great a number, that a conspiracy was formed against Him on account of the multitude of His followers; but also, that when He became a soul, without the covering of the body, He dwelt among those souls which were without bodily covering, converting such of them as were willing to Himself, or those whom He saw, for reasons known to Him alone, to be better adapted to such a course.
