In other words, the fundamental philosophical problem of Christology is the problem that arises when a single subject bears incompatible properties. Christ seems to be both necessarily omniscient, as the divine Son, the second person of the Trinity, and yet also limited in knowledge, as the human man, Jesus of Nazareth—and so on for other divine and human attributes. Yet Christ is one person, not two: he just is the divine Son and he just is Jesus of Nazareth. On standard interpretations of logical consistency, nothing can have logically incompatible properties at the same time and in the same respect—hence the problem.
