A paradox adapted from the well-known 'paradox of increase ' has been formulated against composite Christology in recent literature. I argue that concrete -composite Christologists can reply by denying the premise that the pre-incarnate divine nature = the Second Person of the Trinity. This denial can be made by modifying a hylomorphic theory of individuals. Using an analogy from material coinciding objects, this modified theory provides an illuminating account of how a person can gain parts over time but remain numerically (...) identical, and it demonstrates that concrete nature and person are not the same thing.
