Nevertheless, Christians believe that Jesus has a body only because he is incarnated. The Father was never incarnated and thus is still without form in Christianity. You'll have to ask Christians what "the express image" means, but I can guarantee they won't say it means a physical similarity.
Of course they'll say it has nothing to do with a physical similarity, which in my opinion is preposterous. An image is the representation of someone or something's physical appearance. Whenever anyone uses the word "image" in a sentence, that's how they use it. I can't think of a single exception (aside from its use in the Bible, where for some reason an entirely new definition of the word emerges). As far as the Father never having been incarnated, I don't know that we can say that with any degree of certainty. We have no account of His incarnation but I wouldn't automatically dismiss the idea as false. The Bible, after all, starts with "the beginning." If it was "in the beginning" when God created the earth, and if He has always existed, what was He doing before the clock started ticking, so to speak?
As I said in my opening remarks, God was never created or born, nor will he die, thus he has no need of procreation. It follows that he has no sexual organs or gender.
Yes, I understand your position, and I have no desire to try to change it. I am, however, going to ask a question that may be more pertinent to other Christians, Christians who believe that God has no form. If Jesus truly was a human being, then he must have had 46 chromosomes, one strand of 23 which He got from His mother and another strand of 23 which He got from His Father. As to how His conception took place, the Bible doesn't really tell us. But I'm wondering where the human being known as Jesus got his second strand of chromosomes. Did He get them from a spirit?
