Somehow, for Protestants, that isn't enough.

Maggie:
Anything else besides being His mother?

Somehow, for Protestants, that isn't enough. Yet they claim to love Christ? Go figger.

Like, say, free from the stain of sin? Immaculately conceived?

Same thing. And yes. In the true Bible, Scripture says:

Hail, "kecharitomene". Which means "ever full of grace". Where there is fullness of grace no sin can exist.

Did He refer to her as the mother of God?

Scripture does. You do believe that Scripture is inspired by the Holy Spirit, don't you? And therefore without error.Luke 1:43-45

King James Version (KJV)
⁴³ And whence is this to me, that the mother of my Lord should come to me?
⁴⁴ For, lo, as soon as the voice of thy salutation sounded in mine ears, the babe leaped in my womb for joy.
⁴⁵ And blessed is she that believed: for there shall be a performance of those things which were told her from the Lord.

Lets break this down:
1. The word "Lord" is here mentioned two times.
2. In the second instance, it is an obvious reference to God. "Blessed is she who believes that the LORD would fulfill His promises." That is an obvious reference to God.
3. Therefore, then, what could she possibly have meant when she said, "mother of my LORD"?
4. Since she was inspired by the Holy Spirit to utter these words, she must have meant what is most obvious. Is Jesus, God? Yes. Therefore, the words she uttered could also be translated, "mother of my GOD".
5. So, God explicitly teaches us, in His Word, that Mary is the Mother of God.

Did He tell us we should direct our prayers to her?

Not explicitly, but by example. As Jesus is the child of Mary, we know that He depended upon her for His every need and that He must have requested many things of her. And that is the meaning of the word, "pray". To request.

In addition, Scripture teaches to praise Mary. 


Luke 1:26-28
King James Version (KJV)
26 And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth,27 To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin's name was Mary.28 And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women.


Let's break this down:


ANGEL GABRIEL
1. an angel is a messenger of God. That is what the word, angel, means.
2. this angel, Gabriel, is one of the four angels that stands before the throne of God.


WAS SENT FROM GOD
1. God sent this angel to Mary.
2. Since this angel is a messenger of God's, God sent Him to deliver a message.
3. Therefore, the angel was not speaking on his own, but was communicating God's message to Mary.
4. If we skip down to verse 28, we see that this was a message of praise (i.e. blessed art thou).
5. Therefore God praised Mary through His Angel.


That is great praise indeed. Do you know of any man whose praise is worth more than God's? In other words, what do you value more highly, the praise of man or the praise of God?


But, there's more. God sent the Angel to do His Will. What is His Will. Obviously, God sent the Angel to deliver a message of praise. Therefore it is God's will that the Angels praise Mary.


And there's yet more. Because the Holy Spirit inspired a holy woman to exclaim, ""Blessed are you among women, and blessed is the child you will bear! "still in:


Luke 1:41-45
King James Version (KJV)
41 And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost: 42 And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb.


Should we break this down?
1. The Holy Spirit is God the Third Person of the Holy Trinity.
2. Therefore, God inspired Elisabeth to praise Mary.
3. This praise is inscribed in the Word of God for all generations.
4. Since Elisabeth is a member of the human race, then it is safe to conclude that God wills that men praise Mary.
5. And we find, again, that God praised Mary through His Saint. Saint Elisabeth praised Mary when she was inspired by the Holy Spirit to do so. That means that it is the Holy Spirit's praise which she passed on. That is why Scripture is called the Word of God. Because it is inspired by the Holy Spirit.
