Very strange tone to this comment, as if you are the all-knowing teacher and I am a recalcitrant student.

And, please sir, allow me to use my own method. If it is you I am challenging, then it is your words that are the object of the "work".

Yes, to deny the divinity of Christ would be a heresy. [Does the author you criticise do this explicitly?]

However, it would also be heresy to deny the humanity of Christ. [Using the same kind of simplistic approach as yours, then some might judge your alleged "correction" as falling into this error.]

Christian faith requires maintaining a delicate balance of recognising both Christ's divinity and humanity. Within understanding this balance, there is room for asking questions about Jesus' own self-awareness of what it meant to "Son of God"; and for exploring the Church's evolving understanding about what the expression "Son of God" means.

Not, I suspect, an exploration, that interests you.
