To start talking about the collective ''humanity'' is to misunderstand the incarnation. Jesus did not not incarnate as humanity but as a human.
Ok. But a human is imperfect. That is one of the characteristics of being human - your imperfections -physiologically, intellectually, emotionally, chemically, psychologically etc; The human body is vulnerable, therefore imperfect. The human mind is vulnerable, therefore imperfect.
I agree all but one of humanity is imperfect.
I am not seeing how that statement is different from asserting that a woman can have a penis?
Most people on this board would reject the notion of perfection presumably because they think it cannot be or imperfection of humanity.
Not sure about rejecting the notion of perfection. We can all see imperfections therefore it makes sense to come up with the notion that something free of imperfections would be the definition of perfect. A flawed vulnerable human body and mind would have imperfections. The possibility exists that something that is not a human body or mind could be perfect.
None of us would be able to demonstrate that anything is perfect so I would think most people on this board could only assert perfection about something - the same way a person asserts gender.
Jesus is firstly the ultimate in humanity, secondly he is the perfect human being, thirdly sin is nailed down as that which stops us from being perfect.
The imperfection of sin, which is some chemical/spiritual/moral/emotional/ psychological imperfection observed in a human is part of the definition of being human. Unless the word "sin" means something else to you? To me saying that Jesus is without sin but also human is like saying a person with a penis is a woman - for me it just does not compute - either human and imperfect or not human and perfect but human and perfect sounds meaningless - what is the need for asserting the human part? Of course anyone can assert it, and some/ many may and do enthusiastically support the idea of human and perfect but my point is that it's not surprising if other people shrug their shoulders and find it too meaningless to engage with other than out of politeness.
I do not see how using words in such stark and concrete terms as I am doing makes them meaningless or what my discussion has to do with your analogy.
Yes I get that you cannot see my point, in the same way that I cannot understand your "human but perfect" point. We are each limited to what we can see. Not really sure what either of us can do to understand something if it just doesn't make sense to us.
To my mind it is the mealy mouthed ''know what I mean'' euphemistic, understatement of middle class people that renders english meaningless.
You're right - language and how it is used is imperfect. That was my point - it's not really surprising that some / many people aren't convinced by imperfect arguments in imperfect languages about abstract concepts.
