Hope its ok to answer some now, some later ...
sorry - if I remember correctly
Compare - John "lifted" the term "logos" and "filled it" with Christ. The early Christians lifted the term "episkopos" and gave it a similar but now Christian filled meaning. Consider, some gnostics taught "abstaining from marriage", both Christ and Paul support virginity. Are Christ and Paul gnostics, or there in a difference in understanding.
The virginity of the Theotokos arises from, is the result of a spiritual disposition. The renaming "no sex ever" is skin-deep.
The spiritual disposition has as a result a physical fact. If it is the physical that gives rise to the spiritual all virgins would be Saints.
Further, we have used the terminology "ever-virgin" for centuries - and it is Christian terminology. "No sex ever" redirects the understanding to a physical understanding alone, and shaves the origin of the state from the ever-virginity of Mary.
What is the point of renaming ? Shall we also rename Trinitarian doctrine ?
Is it spiritually important, or physically important or both ?
So then, the term "logos" is uneffected by its use in the Gospel of John, and the term episkopos is still a political term with legal and military overtones ? Yes, logos is used in relation to speak in Genesis, and retains its meaning "word, reason, etc" but are not somewhat altered and richer for their Christian use over centuries ?
It includes the meaning of no intercourse. The iteration of the doctrine came later, and is more extensive. Even Paul notes that remaining virgin allows one to be more focused on God. Does he locate this teaching soley in the fact of sex ?
Again, the condition of "not having sex" arises from something else, is a "symptom" of the something it arises from. Not having sex is a part, not the whole. Likewise, "be fruitful and multiply" arises from something, it is not "about sex".
Which came first - the purpose or the physical ? In this case, too the physical arises from the spiritual purpose - the meaning is not an "add-on" to the physical fact. The physical fact "flows from" the spiritual purpose.
I hope this makes sense ...
