And please, not the false claim Mary is our mother. She's only the mother of Christ.....and her's and Joseph's biological kids.
By the way, from your New Testament:
[26] When Jesus therefore had seen his mother and the disciple standing whom he loved, he saith to his mother: Woman, behold thy son. [27] After that, he saith to the disciple: Behold thy mother. And from that hour, the disciple took her to his own.
John 19
Mary is not an idol, She is the Mother of Jesus Christ, true God and true Man.
