Interesting. However, he doesn't address the root word of "individual," which denote "something that cannot be divided." I think this is a useful concept in regard to human persons, whose humanity, while "composed of body and soul," does not allow for those qualities to be separated, and also for Jesus Christ, whose human and divine natures are individual parts of His Person. "Individual" might be sort of a shorthand for "hypostatic union." :-).
Whoops, that was poorly phrased. I mean, the Person of Christ is one, indivisible Person, composed of two natures.
You've touched upon the same issue that first came to my mind. The use of the word 'individual' begs the question. Granted that most people who use the term, generally mean something other than the explicit semantic definition, this point touches upon a general point of view that may be more endemic to our Western thinking than we might perceive.
The New Testament definitely refers to the anthropology of man in terms of body, soul and spirit. The trichotomous composition of Adam prior to the fall and of the second Adam, as well as those who are regenerated in the spirit at the point of being born-again.
We are still appointed to suffer the first death, a separation of soul from body. The term 'individual' might induce some complicated fallacies if argued to explicitly, because man is not in-divisible, but rather very divisible. Discernible aspects of body, soul and spirit are the crux of understanding the Christian way of life, an occupation with Christ, and taking on the mind of Christ.
