In Sacred Scripture we are told that man was created “in the image of God” (Gen 1:26). However, only the second person of the Blessed Trinity, the Son, is the perfect image and likeness of the Father. “The image [likeness] of a thing may be found in something else in two ways; in one way it is found in something of the same specific nature–as the image of the king is found in his son; in another way it is found in something of a different nature, as the king’s image on the coin. In the first sense the Son is the image of the Father; in the second sense man is called the image of God; and therefore in order to express the imperfect character of the divine image in man, man is not simply called ‘the image’ but is referred to as being ‘according to the image’, whereby is expressed a certain movement or tendency to perfection. But it cannot be said that the Son of God is ‘according to the image’, because he is the perfect image of the Father” (“Summa Theologiae”, I, q. 35, a. 2 ad 3). And so, “for something to be truly an image, it has to proceed from another as similar to it in species, or at least in some aspect of the species” (“Summa Theologiae”, I, q. 35, a. 1, c.) To say that the Son is “image of the invisible God” means that the Father and the Son are one-in-substance–that is, both possess the same divine nature–, with the nuance that the Son proceeds from the Father. It also conveys the fact that they are two distinct persons, for no one is the image of himself.
The supreme revelation of God is that effected by the Son of God through his Incarnation. He is the only one who can say, “He who has seen me has seen the Father” (Jn 14:9). His sacred humanity, therefore, reflects the perfections of God, which he possesses by virtue of the hypostatic union–the union of divine nature and human nature which occurs in his person, which is divine. The second Person of the Trinity restored man to his original dignity. The image of God, imperfect though it be, which there is in every man and woman, was blurred by Adam’s sin; but it was restored in Christ: God’s true self-image takes on a nature the same as ours, and thanks to the redemption wrought by his death, we obtain forgiveness of sins (v. 14).
Jesus Christ is the “first-born of all creation” by virtue of the hypostatic union. He is, of course, prior to all creation, for he proceeds eternally from the Father by generation. This the Church has always believed, and it proclaims it in the Creed: “born of the Father before time began …, begotten, not made, of one being [consubstantial] with the Father” (“Nicene-Constantinopolitan Creed”).
In Jewish culture, the first-born was first in honor and in law. When the Apostle calls Jesus “the first-born of all creation”, he is referring to the fact that Christ has pre-eminence and headship over all created things, because not only does he pre-date them but they were all created “through him” and “for him” (v. 16).
16-17. Jesus Christ is God; this is why he has pre-eminence over all created things. The relationships between Christ and creation are spelled out by three prepositions. “In him all things were created”: in Christ: he is their source, their center and their model or exemplary cause. “All things were created through him and for him”: through him, in other words, God the Father, through God the Son, creates all things; and for him, because he is the last end, the purpose or goal of everything.
St Paul goes on to say that “in him all things hold together”; “the Son of God has not only created everything: he conserves everything in being; thus, if his sovereign will were to cease to operate for even an instant, everything would return into the nothingness from which he drew everything that exists” (Chrysostom, “Hom. on Col, ad loc.”).
All created things, then, continue in existence because they share, albeit in a limited way, in Christ’s infinite fullness of existence or perfection. His dominion extends not only over celestial things but also over all material things, however insignificant they may seem: it embraces everything in heaven and in the physical universe.
The sacred text also points to Christ’s supremacy over invisible creation, that is, over the angels and celestial hierarchies (cf. Heb 1:5). If St Paul stresses this fact, it is to expose the errors of those who were depicting Jesus as a creature intermediary between
corporeal beings and spiritual created beings, and, therefore, lower than the angels.
18. “He is the head of the body, the church”: this image shows the relationship of Christ with the Church, to which he sends his grace in abundance, bearing life to all its members. 'The head," St Augustine says, “is our very Savior, who suffered under Pontius Pilate and now, after rising from the dead, is seated at the right hand of the Father. And his body is the Church …] For the whole Church, made up of the assembly of the faithful–for all the faithful are Christ’s members–has Christ, as its head, who rules his body from on high” (“Enarrationes in Psalmos”, 56, 1).
