I doubt "individual" has so much meaning in ordinary use. "We arrested three individuals" is merely a fancy way of saying "We took in three guys".
I agree with A.J. that most of the time, individual is just a short-hand for one person, and nothing theological need be read into it.
I also agree with K that Christianity is intrinsically tied up with community, and that the language of individualism is not perhaps a felicitous choice for those who want to fully express who a man is.
It has been said that at the root of nearly all the ancient heresies (most of which regularly pop up periodically in different forms) was the confusion of nature and person (hypostasis). Or put more simply, the confusion of "what" with "who."
The fathers wrote, as I recall, that the Divine essence and nature are uniquely enhypostasized as Father, Son, and Holy Spirit. Likewise, human nature is uniquely enhypostasized in each human being (and was also uniquely enhypostasized in the hypostasis/person of Jesus Christ.) Uniqueness and community are not in dialectical opposition with each other, although some of the pagan Greek philosophers felt otherwise -- A.J. knows more about those guys than I do.
This shared single human nature is what makes Christ the living bridge between God and man. This connectedness of the single human nature is why Christ's incarnation, life, death, and resurrection has transformed and healed human nature, making it possible for us to achieve salvation, and to be one day resurrected.
If by calling Christ an "individual," one fails to consider Christ's shared divine essence and nature, we end up with 3 gods at best, and with subordinationism and a "creaturely Christ" Arianism at worst. If by calling Christ an "individual," one fails to consider Christ's sharing of human nature with us, then we make Christ's work of no effect for us.
Of course, it is what it is -- what we believe doesn't change who God is and who we are. But what we believe does change how we think and act, and how we respond to God. And how we think and act affects our ability to change to become like Christ and to draw closer to him.
