why has Satan tempted your heart:
But can the devil put anything into our hearts? It seems he can, for a Psalm speaks of things "sent by evil angels" [Ps 77:49]. To explain this, we should note that what is in a person's thought and will is said to be in his heart. Understanding it the above way, there are two ways something can be put into our heart. First, directly; and in this way only one who has the power to move our will from within can put something into our heart. Only God can do this; But because the will is also moved by an external object, something apprehended as a good, it follows that anyone who brings to mind, or suggests that something is good is said to put something into our heart indirectly, by making us apprehend something as good, which in turn moves our will. This happens in two ways. By an external suggestion, and then one person can put something into another's heart; or by an interior suggestion, which is the way the devil puts something into our heart. For our imagination, since it is a physical reality, is subject to the power of the devil when God allows it. So, whether we be awake or asleep, he forms in it certain images which, when apprehended, move our will to desire something. And so the devil puts something into our heart, not directly by moving our heart, but indirectly, by suggestion

These words of Peter [1 Peter 3:19] are referred by some to Christ's descent into hell: and they explain it in this sense: "Christ preached to them who formerly were unbelievers, and who were shut up in prison"—that is, in hell—"in spirit"—that is, by His soul. Hence Damascene says (De Fide Orth. iii): "As He evangelized them who are upon the earth, so did He those who were in hell"; not in order to convert unbelievers unto belief, but to put them to shame for their unbelief, since preaching cannot be understood otherwise than as the open manifesting of His Godhead. which was laid bare before them in the lower regions by His descending in power into hell.

Augustine, however, furnishes a better exposition of the text in his Epistle to Evodius quoted above, namely, that the preaching is not to be referred to Christ's descent into hell, but to the operation of His Godhead, to which He gave effect from the beginning of the world. Consequently, the sense is, that "to those (spirits) that were in prison"—that is, living in the mortal body, which is, as it were, the soul's prison-house—"by the spirit" of His Godhead "He came and preached" by internal inspirations, and from without by the admonitions spoken by the righteous: to those, I say, He preached "which had been some time incredulous," i.e. not believing in the preaching of Noah, "when they waited for the patience of God," whereby the chastisement of the Deluge was put off: accordingly (Peter) adds: "In the days of Noah, when the Ark was being built."

I answer that, As Christ, in order to take our penalties upon Himself, willed His body to be laid in the tomb, so likewise He willed His soul to descend into hell. But the body lay in the tomb for a day and two nights, so as to demonstrate the truth of His death. Consequently, it is to be believed that His soul was in hell, in order that it might be brought back out of hell simultaneously with His body from the tomb.

Reply to Objection 1. When Christ descended into hell He delivered the saints who were there, not by leading them out at once from the confines of hell, but by enlightening them with the light of glory in hell itself. Nevertheless it was fitting that His soul should abide in hell as long as His body remained in the tomb.

Reply to Objection 2. By the expression "bars of hell" are understood the obstacles which kept the holy Fathers from quitting hell, through the guilt of our first parent's sin; and these bars Christ burst asunder by the power of His Passion on descending into hell: nevertheless He chose to remain in hell for some time, for the reason stated above.

Reply to Objection 3. Our Lord's expression is not to be understood of the earthly corporeal paradise, but of a spiritual one, in which all are said to be who enjoy the Divine glory. Accordingly, the thief descended locally into hell with Christ, because it was said to him: "This day thou shalt be with Me in paradise"; still as to reward he was in paradise, because he enjoyed Christ's Godhead just as the other saints did.

1) "Of time." Things are said to be created in the beginning of time, not as if the beginning of time were a measure of creation, but because together with time heaven and earth were created.
2) In the Son." In the Son by reason of wisdom, in order that, as it is said (Psalm 103:24), "Thou hast made all things in wisdom," it may be understood that God made all things in the beginning--that is, in the Son; according to the word of the Apostle (Colossians 1:16), "In Him"--the Son--"were created all things.
3) Before all things--Nothing is made except as it exists. But nothing exists of time except "now." Hence time cannot be made except according to some "now"; not because in the first "now" is time, but because from it time begins.
God: That is to say the Father, Son and Holy Ghost. The Hebrew original has "Elohim," which may be rendered "Gods" or "Judges": Various languages have diverse modes of expression. So as by reason of the plurality of "supposita" the Greeks said "three hypostases," so also in Hebrew "Elohim" is in the plural. We, however, do not apply the plural either to "God" or to "substance," Though the name "God" signifies a being having Godhead, nevertheless the mode of signification is different. For the name "God" is used substantively; whereas "having Godhead" is used adjectively. Consequently, although there are "three having Godhead," it does not follow that there are three Gods.
Created: To be created is, in a manner, to be made. Creation is not change, but is understood as first not existing at all, and afterwards as existing. The gloss has, "To create is to make something from nothing." To create belongs to God according to His being, that is, His essence, which is common to the three Persons of the whole Trinity. The angels were created at the same time as corporeal creatures. For the angels are part of the universe: they do not constitute a universe of themselves; but both they and corporeal natures unite in constituting one universe. At the same time the contrary is not to be deemed erroneous; especially on account of the opinion of Gregory Nazianzen. For Jerome says (In Ep. ad ***. i, 2): "Six thousand years of our time have not yet elapsed; yet how shall we measure the time, how shall we count the ages, in which the Angels, Thrones, Dominations, and the other orders served God?" Damascene also says (De Fide Orth. ii): "Some say that the angels were begotten before all creation; as Gregory the Theologian declares, He first of all devised the angelic and heavenly powers, and the devising was the making thereof."
Heaven: According to Chrysostom (Hom. iii in Genes.), Moses prefaces his record by speaking of the works of God collectively, in the words, "In the beginning God created heaven and earth," and then proceeds to explain them part by part; in somewhat the same way as one might say: "This house was constructed by that builder," and then add: "First, he laid the foundations, then built the walls, and thirdly, put on the roof." In accepting this explanation we are, therefore, not bound to hold that a different heaven is spoken of in the words: "In the beginning God created heaven and earth," and when we read that the firmament was made on the second day.
We may also say that the heaven recorded as created in the beginning is not the same as that made on the second day; and there are several senses in which this may be understood. Augustine says (Gen. ad lit. i, 9) that the heaven recorded as made on the first day is the formless spiritual nature, and that the heaven of the second day is the corporeal heaven. According to Bede (Hexaem. i) and Strabus, the heaven made on the first day is the eternal one, and the firmament made on the second day, the starry heaven. According to Damascene (De Fide Orth. ii) that of the first day was spherical in form and without stars, the same, in fact, that the philosophers speak of, calling it the ninth sphere, and the primary movable body that moves with diurnal movement: while by the firmament made on the second day he understands the starry heaven. According to another theory, touched upon by Augustine [Gen. ad lit. ii, 1] the heaven made on the first day was the starry heaven, and the firmament made on the second day was that region of the air where the clouds are collected, which is also called heaven, but equivocally. And to show that the word is here used in an equivocal sense, it is expressly said that "God called the firmament heaven"; just as in a preceding verse it said that "God called the light day" (since the word "day" is also used to denote a space of twenty-four hours). Other instances of a similar use occur, as pointed out by Rabbi Moses.
Earth: The earth stands in relation to the heaven as the centre of a circle to its perimeter. But as one center may have many perimeters, so, though there is but one earth, there may be many heavens.

The earth was void: or "invisible," inasmuch as the waters covered and concealed it from view; and the formlessness of the earth. But other holy writers understand by earth the element of earth, in this sense, the earth was, according to them, without form. In other words, they hold that formlessness of matter preceded in time its formation. But St. Augustine believes that the formlessness of matter was not prior in time to its formation, but only in origin or the order of nature,
Empty: or, according to another reading [Septuagint], "shapeless"--that is, unadorned by herbs and plants.
darkness was upon the face of the deep: The formlessness of water, which holds the middle place, is called the "deep," because, as Augustine says (Contr. Faust. xxii, 11), this word signifies the mass of waters without order.
Spirit of God: Rabbi Moses (Perplex. ii) understands by the "Spirit of the Lord," the air or the wind, as Plato also did, and says that it is so called according to the custom of Scripture, in which these things are throughout attributed to God. But according to the holy writers, the Spirit of the Lord signifies the Holy Ghost, Who is said to "move over the water"--that is to say, over what Augustine holds to mean formless matter, lest it should be supposed that God loved of necessity the works He was to produce, as though He stood in need of them. For love of that kind is subject to, not superior to, the object of love. Moreover, it is fittingly implied that the Spirit moved over that which was incomplete and unfinished, since that movement is not one of place, but of pre-eminent power, as Augustine says (Gen. ad lit. i, 7). It is the opinion, however, of Basil (Hom. ii in Hexaem.) that the Spirit moved over the element of water, "fostering and quickening its nature and impressing vital power, as the hen broods over her chickens." For water has especially a life-giving power, since many animals are generated in water, and the seed of all animals is liquid. Also the life of the soul is given by the water of baptism, according to John 3:5: "Unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God." Scripture usually means the Holy Spirit, Who is said to "move over the waters," not, indeed, in bodily shape, but as the craftsman's will may be said to move over the material to which he intends to give a form.

Be light made: I answer, then, with Dionysius (Div. Nom. iv), that the light was the sun's light, formless as yet, being already the solar substance, and possessing illuminative power in a general way, to which was afterwards added the special and determinative power required to produce determinate effects. Thus, then, in the production of this light a triple distinction was made between light and darkness. First, as to the cause, forasmuch as in the substance of the sun we have the cause of light, and in the opaque nature of the earth the cause of darkness. Secondly, as to place, for in one hemisphere there was light, in the other darkness. Thirdly, as to time; because there was light for one and darkness for another in the same hemisphere; and this is signified by the words, "He called the light day, and the darkness night."
Augustine seems to say (De Civ. Dei xi, 9,33) that Moses could not have fittingly passed over the production of the spiritual creature, and therefore when we read, "In the beginning God created heaven and earth," a spiritual nature as yet formless is to be understood by the word "heaven," and formless matter of the corporeal creature by the word "earth." And spiritual nature was formed first, as being of higher dignity than corporeal. The forming, therefore, of this spiritual nature is signified by the production of light, that is to say, of spiritual light. For a spiritual nature receives its form by the enlightenment whereby it is led to adhere to the Word of God.

"And there was evening and morning one day": According to Basil (Hom. ii in Hexaem.), the entire period takes its name, as is customary, from its more important part, the day. And instance of this is found in the words of Jacob, "The days of my pilgrimage," where night is not mentioned at all. But the evening and the morning are mentioned as being the ends of the day, since day begins with morning and ends with evening, or because evening denotes the beginning of night, and morning the beginning of day. It seems fitting, also, that where the first distinction of creatures is described, divisions of time should be denoted only by what marks their beginning. And the reason for mentioning the evening first is that as the evening ends the day, which begins with the light, the termination of the light at evening precedes the termination of the darkness, which ends with the morning. But Chrysostom's explanation is that thereby it is intended to show that the natural day does not end with the evening, but with the morning (Hom. v in Gen.).
Or else it can be said, as Augustine puts it (Gen. ad lit. iv, 23), that there is nothing to prevent us from calling something light in comparison with one thing, and darkness with respect to another. In the same way the life of the faithful and the just is called light in comparison with the wicked, according to Ephesians 5:8: "You were heretofore darkness; but now, light in the Lord": yet this very life of the faithful, when set in contrast to the life of glory, is termed darkness, according to 2 Peter 1:19: "You have the firm prophetic word, whereunto you do well to attend, as to a light that shineth in a dark place." So the angel's knowledge by which he knows things in their own nature, is day in comparison with ignorance or error; yet it is dark in comparison with the vision of the Word.

A firmament: Strabus and Bede teach that there is an eternal heaven, because the firmament, which they take to mean the sidereal heaven, is said to have been made, not in the beginning, but on the second day: whereas the reason given by Basil is that otherwise God would seem to have made darkness His first work. Augustine says (Gen. ad lit. i, 9) that the heaven of the second day is the corporeal heaven. According to Damascene (De Fide Orth. ii) the firmament made on the second day is the starry heaven. Chrysostom understood that the heaven in 1:1 is the same heaven of the second day.
Divide the waters from the waters: Whether, then, we understand by the firmament the starry heaven, or the cloudy region of the air, it is true to say that it divides the waters from the waters, according as we take water to denote formless matter, or any kind of transparent body, as fittingly designated under the name of waters. For the starry heaven divides the lower transparent bodies from the higher, and the cloudy region divides that higher part of the air, where the rain and similar things are generated, from the lower part, which is connected with the water and included under that name.

Firmament: Not that in which the stars are set, but the part of the atmosphere where the clouds are collected, and which has received the name firmament from the firmness and density of the air. "For a body is called firm," that is dense and solid, "thereby differing from a mathematical body" as is remarked by Basil (Hom. iii in Hexaem.).

Above the firmament: The waters above the firmament must rather be the vapors resolved from the waters which are raised above a part of the atmosphere, and from which the rain falls. As to the nature of these waters, all are not agreed. Origen says (Hom. i in Gen.) that the waters that are above the firmament are "spiritual substances." Wherefore it is written (Psalm 148:4): "Let the waters that are above the heavens praise the name of the Lord," and (Daniel 3:60): "Ye waters that are above the heavens, bless the Lord." To this Basil answers (Hom. iii in Hexaem.) that these words do not mean that these waters are rational creatures, but that "the thoughtful contemplation of them by those who understand fulfils the glory of the Creator." Hence in the same context, fire, hail, and other like creatures, are invoked in the same way, though no one would attribute reason to these. We must hold, then, these waters to be material, but their exact nature will be differently defined according as opinions on the firmament differ.
