I have no idea why you inserted that Jesus is at the right hand of God the Father. That was not part of my post you quoted and I decline to mix that with this discussion of grace and Mary.
Let me start by reporting what I found with a quick Google of the Wycliffe Bible. According to Wikipedia, its original text was translated from the Latin Vulgate Bible, which, when Googled, Wikipedia shows it was the first Bible of the Catholic Church. That explains why Luke 1:28 contains 'full of grace'. I'm not trying to create a 'battle of translations' here...only an explanation of why Wycliffe and Douay-Rheims appear to be the only versions that contain 'full of grace'.
Let's look at John 1:14-17 in more detail -
Joh 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
Joh 1:15 John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh after me is preferred before me: for he was before me.
Joh 1:16 And of his fulness have all we received, and grace for grace.
Joh 1:17 For the law was given by Moses, but grace and truth came by Jesus Christ. (KJV)
As verse 14 shows, Jesus is the one full of grace. Your statement concerning Jesus came through Mary, while being accurate, seems to me to imply that Jesus' grace 'came through Mary' as well. Perhaps I'm misunderstanding what you wrote. Grace is not genetically inherited, and it didn't 'pass through' Mary, either. One might argue that the 'sperm' that God the Father supplied to fertilize the chosen egg within Mary contained grace. Perhaps. But it didn't come from Mary's egg. Since Jesus is 100% God and 100% human, He was automatically full of grace as He is God. One could debate 'when' he first became full of grace endlessly, so it is not and should not be part of this or any other discussion. As an aside, medicine confirmed many years ago that the blood of the mother never mixes with that of the zygote, embryo, fetus, child growing within her. If it did, it would be impossible for a mother to bear a child of a different blood type or different RH factor, both of which happen frequently. It would kill the baby and possibly the mother as well. Which is why they always make sure that transfusions match the donor type and RH with the recipient.
I'm not sure why you included a reference to John 1:23. John 1:19-28 speaks solely of John the Baptist, not John the disciple and author of the Book of John, 3 Epistles, and Revelation.
Joh 1:19 And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, Who art thou?
Joh 1:20 And he confessed, and denied not; but confessed, I am not the Christ.
Joh 1:21 And they asked him, What then? Art thou Elias? And he saith, I am not. Art thou that prophet? And he answered, No.
Joh 1:22 Then said they unto him, Who art thou? that we may give an answer to them that sent us. What sayest thou of thyself?
Joh 1:23 He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias.
Joh 1:24 And they which were sent were of the Pharisees.
Joh 1:25 And they asked him, and said unto him, Why baptizest thou then, if thou be not that Christ, nor Elias, neither that prophet?
Joh 1:26 John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not;
Joh 1:27 He it is, who coming after me is preferred before me, whose shoe's latchet I am not worthy to unloose.
Joh 1:28 These things were done in Bethabara beyond Jordan, where John was baptizing. (KJV)
I'm also not sure why you referenced Genesis 3:15 in relation to Jesus' grace. That is the very first verse of prophecy in the Bible, and must be looked at in the context of Genesis 3:14-16 to fully understand -
Gen 3:14 And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
Gen 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
Gen 3:16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee. (KJV)
Verse 14 shows that God is talking the the serpent, aka, Satan. Even knowing that, it's somewhat difficult to understand who's who in verse 15. 'And I will put enmity between thee (Satan) and the woman (Eve). 'and between thy seed (Satans' descendants) and her seed (Eves' descendants)'. 'it (Jesus) shall bruise thy head' (a moderately severe concussion to Satan, perhaps?, and ties to Revelation 13:3 And I saw one of his heads as it were wounded to death; and his deadly wound was healed: and all the world wondered after the beast. (KJV)) 'and thou (Satan) shalt bruise his (Jesus) heel (He overcame the curse of death and rose again on the 3rd day).
One of the interesting things about the Bible is various symbolism consistently used except when very obvious it's talking about something physical. One of those is the use of 'woman'. It's clear that throughout Revelation, 'woman' always symbolizes Israel. Multiple sources I've read and heard indicate that Genesis 3:15 refers to Eve in the present tense and simultaneously refers to Israel in the future tense. Why is Israel the most hated nation in the world since Jacob? Because if Satan can destroy all Israel (descendants of Abraham, Isaac and Jacob (renamed Israel by God), that would be 'proof' that God lied about Israel being His chosen people and the very numerous prophecies and covenants God made to Israel are null and void, thus making the entire Bible worthless fiction.
Even though God temporarily 'set aside' Israel in 70 AD when the temple was destroyed and went to the Gentiles through Paul and his writings for almost 2000 years thus far, Israel's re-creation in 1948 clearly shows God has started dealing with Israel once again, fulfilling Ezekiel 37 bringing the dried bones - the House of Israel - back together and putting them back in the land He covenanted to the descendants of Abraham in Genesis 15-18 -
Gen 15:18 In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:
Gen 15:19 The Kenites, and the Kenizzites, and the Kadmonites,
Gen 15:20 And the Hittites, and the Perizzites, and the Rephaims,
Gen 15:21 And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites. (KJV)
The war that immediately followed Israels' becoming a nation again (By the way, President Truman was the first world leader to publicly acknowledge Israel as a nation), the 6-Day War and the Yom Kippur War are all evidence that God is once again guiding Israel to victories. Trumps' declaration that Jerusalem is the capitol of Israel is further fulfillment of Israels' prophetic restoration. No other nation, once scattered around the globe, has ever come back together again other than Israel. God is in control!
