As far as Mary being held in high esteem in Islam. I feel the same way on how Catholics hold Mary in high esteem compared to Jesus. Catholics even believe that Mary was a virgin for life. How can she when Jesus had 2 brothers and a sister?
How high do you think Catholics hold Mary compared to Jesus? I see nothing to suggest the same level. If one were to believe in Jesus and the birth told in the bible, why would anyone think Mary would live a "normal" life? How could she? It would take me some research and I'm not sure I'm up to it, but there is a reference to a brethren of Christ that is a known cousin and not a sibling since there was no word for cousin.
Mary is held in high esteem because she did what Eve didn't and I've seen referenced as the second Eve or a redo on the mistakes of the first as part of God's family. I've read others to compare her to the Ark of the Covenant in that she "too" contained the Word of God and like the Ark was brought out in battle. I'm sure there are many other comparisons, but I'm certainly not well versed on Marian understanding. Considering the time, it is somewhat amazing that a woman during that time was held in high esteem...and this reminded me of another in my old feeble mind. This is taking back many years. I believe I recall, and this can be verified easily if correct, that Eve was called "woman" until she sinned at which point she was Eve. Mary was called "woman" by Jesus and so you can draw some conclusions on that. Name change took place in a significant event such as when Jesus change Simons name to Peter as a result of the following:
Peter’s Declaration about Jesus
13 Now when Jesus came into the district of Caesare′a Philippi, he asked his disciples, “Who do men say that the Son of man is?” 14 And they said, “Some say John the Baptist, others say Eli′jah, and others Jeremiah or one of the prophets.” 15 He said to them, “But who do you say that I am?” 16
Simon Peter replied, “You are the Christ, the Son of the living God.” 17 And Jesus answered him,
“Blessed are you, Simon Bar-Jona! For flesh and blood has not revealed this to you, but my Father who is in heaven. 18
And I tell you, you are Peter,[
b] and on this rock[
c] I will build my church, and the powers of death[
d] shall not prevail against it. 19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” 20 Then he strictly charged the disciples to tell no one that he was the Christ. This can lead to a discussion on the meaning of Peter and debates will rage whether it was "rock" or pebble, but that too can get long.
Here is another part that Protestant and Catholics differ. Catholic see Mary (the second Eve that did God's will) as the "mother" of Christianity and Protestants see her as a vessel only...just as they view John Chapter 6 differently from each other. CAtholics take that literally and Protestants take it figuratively as far as Communion versus the Eucharist
But standing by the cross of Jesus were his mother, and his mother’s sister, Mary the wife of Clopas, and Mary Mag′dalene. 26 When Jesus saw his mother, and the disciple whom he loved standing near, he said to his mother,
“Woman, behold, your son!” 27 Then he said to the disciple, “
Behold, your mother!” And from that hour the disciple took her to his own home.
That was off the top of my head. I'm sure some may be able to explain Mary's position better. BTW, I have no problems with either denomination. I actually tend to believe that different churches can be better at different times of a persons life, but that too is for another day as this can get rather lengthy to provide context rather than just throwing out an unfounded opinion.
BTW, Peter's declaration is reconfirmed after Jesus returns after the resurrection...and after Peter has denied Christ which he said he would NEVERE do...before Cock crowed (3 AM?? roughly I seem to recall). Jesus then tells Peter to feed his sheep "three" times as a reminder of his three denials and asks if he loves Him. John 21:15-25
