When talking about a subject, particularly a complex subject, it is tempting and often helpful to break the subject down into smaller components and detail each part and then mentally reassemble the parts back into the whole. As a heuristic method it has value. The downside, however, is that some subjects are more than the sum of their parts.
It is normal for theologies to separate the Person of Christ from the Work of Christ. The person of Christ usually referring to such matters as the hypostatic union (the uniting of the divine and human natures in Christ which we wrote about here) and creeds like Chalcedon etc. The work of Christ unusually referring to his work or reconciliation and atonement.
A Christological axiom is that the person and work of Christ can’t be separated. As I understand it what is normally meant is that you can’t understand the work of Christ without understanding his person. If Jesus isn’t both fully man and fully God then the cross is either nonsense or immoral. And likewise you can’t understand the person without understanding what he came to earth to achieve. And this is true.
But what’s misleading about this axiom is that it implies that the person and work of Christ really are two separate thoughts that simply need to be kept near each other, perhaps even next to each other. But that’s not exactly how it is.
