I started writing this as a response to Danny’s comment, but the post ended up being so long that I am making it into its own article.
“Moses could not enter the Tent of Meeting because the cloud had settled upon it, and the glory of the LORD filled the tabernacle.” (Ex 40:35) Was God glorious because He created the world or because of His nature? Was His claim to fame at that point in time creation or His essential goodness and holiness? In that particular quote “glory” indeed appears to mean holiness, such that no man could stand in the presence of God, for while on earth, one is not confirmed in goodness. Even Moses must have had something of which he was ashamed — it is written later that “This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God.” (Jn 3:19-21) But at the same time in this same quote we see a hint that glory could be taken to mean reputation: “so that it may be seen plainly that what he has done has been done through God,” bestowed on the condition of deserving deeds. Aquinas apparently takes the same position as I do:
Glory signifies a certain clarity, wherefore Augustine says… that to be “glorified is the same as to be clarified.” Now clarity and comeliness imply a certain display: wherefore the word glory properly denotes the display of something as regards its seeming comely in the sight of men, whether it be a bodily or a spiritual good. Since, however, that which is clear simply can be seen by many, and by those who are far away, it follows that the word glory properly denotes that somebody’s good is known and approved by many…
But if we take the word glory in a broader sense, it not only consists in the knowledge of many, but also in the knowledge of few, or of one, or of oneself alone, as when one considers one’s own good as being worthy of praise. (ST, II-II, 132, 1)
Now one can object that glory is not reputation but rather a state of character. Good deeds, works of mercy, and so on, shape character, and so it is not the doing of good but being good that is glorious. On this view, God would indeed possess glory simply for being Himself. And we can certainly distinguish between these two meanings of our word. God is glorious for His character but is also glorious for His temporal acts of creation, redemption, and sanctification.
Now as for the division of labor between the persons, remember that human beings posit ends and seek to attain them; they have purposes or goals. In order for a goal to be achieved, exactly three things are necessary: love of the end, knowledge of the means to that end, that is, how that task can be accomplished, and power to overcome the obstacles standing in the way to the end. And since we are made in the image of God, we can ascribe to the Trinity these three aspects of our human experience. Alternatively, we can say that the Father represents the essence, the Son proceeds (from the Father) as the word of the intellect and the totality of God’s self-knowledge, and the Holy Spirit, as the love of the will and the infinitude of His self-love. In us the intellect and will are not persons, but in God they are. Which is arguably pretty remarkable. (NB: God’s interrelations within His nature and His relations with the creation are two different things, and I have a whole theory of how it works; see my earlier posts.)
Danny quotes “For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities — all things have been created by Him and for Him. And He is before all things, and in Him all things hold together.” (Col 1:16-17) “By” Him means, with the help of His know-how. “For” Him, that He inherited the world from the Father as a consequence of the Incarnation, such that “the Father judges no one, but has entrusted all judgment to the Son.” (Jn 5:22) “In” Him, that the global and local unities-in-variety, the network of causal laws, etc., are related to each other according to the Son’s grand design. The world is rational, “rational” having the same root as “ratio”; so everything is ordered and fits together in some proportion or other.
Now does this mean that the pre-incarnate Son, too, had glory (in the second sense of reputation), since He participated in the creation of the world? The answer lies hidden in the fact that the person of the Father is the “principle” of both the Son, the Holy Spirit, and the created world. He is the principle of their existence either by nature or by will, Himself unbegotten and uncreated, and so giving existence is the particular function of the Father. If in the Nicene creed we read that “through [the Son] all things were made,” then it is also true that from the Father all things were made. And it is to underscore this matter of causation (though Aquinas rightly points out that “principle” is a more general term than “cause,” because “in all kinds of causes there is always to be found between the cause and the effect a distance of perfection or of power: whereas we use the term ‘principle’ even in things which have no such difference, but have only a certain order to each other” (ST, I, 33, 1)) that we specifically call the Father the Creator.
Indeed, analogously, all three persons can be called the Redeemers and Sanctifiers. For example, the Father took part in the Incarnation by preparing the ground for it via Israel, by agreeing to send the Son, by speaking from the heavens “This is my Son, whom I love; with him I am well pleased. Listen to him!” (Mt 17:5) and who knows what else. Jesus is also full of the Holy Spirit, and, e.g., “Then Jesus was led by the Spirit into the desert to be tempted by the devil.” (Mt 4:1) But Christ is specifically called the Redeemer, because He is the one who suffered and died so that sins may be forgiven. And similarly for the Sanctifier.
