I don't think Jesus was born from a virgin. Can any (other?*) Christians explain why they say that as well as why it matters?
Matthew 1:22-23 explicitly says he was
The section on "Proof from Scripture" does not impress you? Consider that the doctrine of the Trinity, which is central to the Nicene Creed and considered by almost all Christians to be necessary to be a Christian, isn't in scripture either. If that can be inferred, surely other things can.
Not explicitly or connectedly, but most 0f the salient points are there. Matthew 1:23 comes in again here, "...they shall call him immanuel, meaning 'God is with us'", since his actual
name was Jesus/ieshua, this can be taken as meaning that people said that he was god among men, and since the referenced prophecy was not in regard to a false prophet or chosen one the implication is therefore that this public opinion was correct.
Furthermore the Holy Spirit can be blasphemed against and is therefore implicitly an aspect of God. You can't blaspheme against a mere angel or prophet.
What IS absent however is any sort of explicit or strongly implicit preclusion against additional aspects. Though he principle of parsimony would suggest against positing additional ones unnecessarily.
The incident in genesis with the three travelers that represent god could imply that three is the preferred number. Conversely, in favor of the possibility of additional aspects are the repeated references in Revelation to "seven spirits of God"
but whoever blasphemes against the Holy Spirit will never be forgiven; they are guilty of an eternal sin
Anyone who CHOOSES to not accept the Holy Spirit will not be forgiven for obvious reasons.
The contrariness to godly virtue is obvious. But imterpreted as you put it the rest of the details are not. Why should it carry a more lasting chastisement than the seemingly equivalent act of refusing to accept Jesus Christ as your lord and savior.
EDIT:
Chalk that one up as a possible argument for the less than three camp
