Bismillah
Let me step in and try to explain what Wael wanted to say regarding the beget issue that you fully accepted and saw nothing wrong with it.
The word beget, I m quite certain that bible scribes never intended to communicate the meaning of man/woman relation that results into begeting children. No but misusing a word to describe a holy process, is not acceptable in a divine book. It falls under the same category when the bible speaks about how:
Luke 1:35 The angel answered, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God. This text also raised controvery, but I think for me it is clear the meaning is clear. Yet it did raise criticism and controversy which was admitted even by some priests. Well anyway.
Also let me help you understand the description of Quran in this regard mean.
Qur'an 19:19-22 Pickthal Translation
(19) He said: I am only a messenger of thy Lord, that I may bestow on thee a faultless son.
(20) She said: How can I have a son when no mortal hath touched me, neither have I been unchaste?
(21) He said: So (it will be). Thy Lord saith: It is easy for Me. And (it will be) that We may make of him a revelation for mankind and a mercy from Us, and it is a thing ordained.
(22) And she conceived him, and she withdrew with him to a far place.
As I do not speak Arabic, I will trust the knowledge of the translator to have accurately transcribe the above verses. As you can see Wael, and as you well know, Islam teaches in the conception of Isa without seed having been ejaculated into Marayam's womb.
To understand this part, you need to start from here:
"She placed a screen (to screen herself) from them; then <b>We sent to her Our Spirit [angel Gabriel], </b>and he appeared before her in the form of a man in all respects.* She said: "Verily! I seek refuge with the Most Beneficent (Allah) from you, if you do fear Allah."(The angel) said: "I am only a Messenger from your Lord, (to announce) to you the gift of a righteous son."She said: "How can I have a son, when no man has touched me, nor am I unchaste?"He said: "So (it will be), your Lord said: 'That is easy for Me (Allah): And (We wish) to appoint him as a sign to humankind and a mercy from Us (Allah), and it is a matter (already) decreed, (by Allah).' "So she conceived him, and she withdrew with him to a far place (i.e. Bethlehem valley about 4-6 miles from Jerusalem)." (Quran 19:17-22)
Pls note the underlined bolded part. This is the core of interest. Now Allah Using the word spirit here, or in Arabic Ruh which is also soul should never be taken as Allah's soul, because if Allah Has a soul/spirit, then He is mortal which is not the case of course.
In other positions in Quran Allah also used the word Ruh to rand Archangle Gabriel because he was the one in charge of taking down revelation to Messengers, and being a revelation carrier and simultaensouly is an angel. The soul has the life , and angles are alive but with no substance, this makes them absolute souls, unlike human beings who are created of substance (mud) then receive the soul to become alive.
Having said that, it becomes quite clear how Allah accurately described who implemented Allah's command of granting Mariam a son without male intervention.
An even more detailed description you will find in (Quran 66:12):
And Mary, the daughter of 'Imran who guarded her chastity; and We breathed into (the sleeve of her shirt or her garment) through Our Spirit [i.e. Gabriel], and she testified to the truth of the Words of her Lord [i.e. believed in the Words of Allah: "Be!" and he was; that is Jesus son of Mary; as a Messenger of Allah], and (also believed in) His Scriptures, and she was of the Qanitin (i.e. obedient to Allah).
Allah Commanded Gabriel to breath into her sleeve, the breath travelled to where it is supposed to land to her womb and she concieved Essa blessing and prayer be upon him. In this context, Allah elquently described the process leaving no doubt for the reader to realise the miraculous conception of Eassa, the chasteness of Mariam blessing and peace be upon them. Most important leaving no way for one to misunderstand or get confused as the son is son of God (astaghferullah). The description is so clear and accurate and most important divine fitting Alhamdulelah.
I think now you can see the difference.
A Divine entity can never misuse a term, word to describe such a landmark in humanity, using the term beget, is demeaning to Allah, Eassa and Mariam blessing and peace be upon them. It means that God is incapable of coming up with a better word. Wael didnt mean to say that bible writers intended to communicate an occurance of intercourse, but rather he wanted to say that this is a bad choice of wording. Bad choice of wording can never be attributed to Allah. May Allah Be Glofiried of what they ascribe to Him.
