I'm well aware of the processes that have gone on in Theology/Christology over the Centuries, but Apologetics are not exegesis/hermeneutics, and basically is just an exercise in justifying beliefs established not on what the Writers wanted their readers to understand.
It is Eisegesis, which as I said above, is an insult to the Text, and if you believe it to be inspired by god, an insult to that god, and a haughty, "Well god obviously meant this", implying he was not capable of saying so.
Of course a magisterium process of later "Revelation" or "Understanding" is necessary, if the original Writings do not confirm the now evolved Theology/Christology.
