Below is a discussion based on a comment to Martin Luther & the Immaculate Conception
Comment: All honor and praise belong to Jesus and Jesus only.
Response: If you mean WORHIP, I agree we are to worship Jesus and not worship Mary. That would be idolotry and is condemned by the Catholic Church. Also, surely you did not mean that our worship belongs to Jesus and only Jesus because then we would be leaving out the Father and the Holy Spirit, the first and third persons of the Holy Trinity.
But I would have to disagree about “honor and praise belong to Jesus and Jesus only”, for several reasons.
First: We are to honor our mother and father. So honoring someone other that Jesus is actually commanded in Sacred Scripture. (Exodus 20 )
Second: Jesus obeyed the Ten Commandments and honored His mother therefore in imitation of Jesus we too honor His mother.
Third: She is also our spiritual mother and therefore also we have another reason to honor her.
Revelation 12:17 Then the dragon was enraged at the woman and went off to make war against the rest of her offspring—those who obey God’s commandments and hold to the testimony of Jesus.
Fourth: We praise many things without worshiping them. So this seems acceptable. I can’t think of anywhere is scripture where it says we can only praise God or Jesus. Could you please support this statement from scripture?
Comment: Mary knew very well that she too had to give honor and praise to her Lord Jesus even though God had found favor in her to give birth to our Lord Jesus. She was just as human as we are and in need of a Savior as she plainly states it in the Magnificat.
Response: You are absolutely correct. Mary gave birth to her God and her Savior. He was her Divine Son.
Comment: We cannot go through her to God because Jesus said no can go to the Father except through Him.
Response: The context of the verse is not talking about prayer or intercession but about attaining Heaven
5Thomas said to him, “Lord, we don’t know where you are going, so how can we know the way?” 6Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.
Prayer to Mary is intercessory prayer which is encouraged. See the post: Prayer to Saints
Comment: He also said there is no other name under heaven in which salvation comes.
Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved.”
Salvation does come from Jesus but by the sovriegn choice of God that salvation, in Christ, comes to us through the assent and cooperation of Mary. She provided the flesh which the second person of the Blessed Trinity assumed to His Divine nature. The God-Man was born of woman. God did not have to do it this way. He could have just created a body to join to his divine nature but He didn’t. He chose to involve Our Blessed Mother. So, we say salvation comes to us from Christ through Mary. She gave birth to our Salvation.
Comment: As for praying to Mary, people should not be be doing this because she is dead. There is nothing she can do for any of us because Ecclesiastes 9:5 says that the dead know nothing.
Response: Only bodies die. Souls are eternal. But we believe that Mary is alive body and soul in Heaven through a special grace of her Divine Son.
