Mark 6:3 says, “Is not this the carpenter, the son of Mary and brother of James and Joses, and Judas and Simon, and are not His sisters here with us?” We need to realize a few things here about these “brothers and sisters.” First, there was no word for cousin, or for nephew or niece, or for aunt or uncle in ancient Hebrew or Aramaic – the words that the Jews used in all those instances were “brother” or “sister.” An example of this can be seen in Gen 14:14, where Lot, who was Abraham’s nephew, is called his brother. Another point to consider: If Jesus had had any brothers, if Mary had had any other sons, it’s hard to believe that the last thing Jesus did on earth was to grievously offend his surviving brothers? What is meant by that is in John 19:26-27, right before Jesus dies, it says that Jesus entrusted the care of His mother to the beloved disciple, John. If Mary had had any other sons, it would have been a bit of a slap in the face to them that the Apostle John was entrusted with the care of their mother. Also, we see from Matthew 27:55-56 that the James and Joses mentioned in Mark 6 as the “brothers” of Jesus are actually the sons of another Mary. And, one other passage to consider is Acts 1:14-15: “[The Apostles] with one accord devoted themselves to prayer, together with the women and Mary the mother of Jesus and with His brothers…the company of persons was in all about a hundred and twenty.” A company of 120 persons composed of the Apostles, Mary, the women, and the “brothers” of Jesus. There were 11 Apostles at the time. Jesus’ mother makes 12. The women were probably the same three women mentioned in Matthew 27, but let’s say it was maybe a dozen or two, just for argument’s sake. So that puts us up to 30 or 40 or so. So that leaves the number of Jesus’ brothers at about 80 or 90! It is hard to argue that Mary had 80 or 90 children. 
 
So Scripture does not contradict the teaching of the Catholic Church about the “brothers” of Jesus, when Scripture is properly interpreted in context.

In Jeremiah 7:18, God is indeed upset with the Israelites for worshipping a false goddess called the “queen of heaven”. However, just because God rebuked them for worshipping the false queen of heaven, doesn’t mean that we cannot pay honor to the true Queen of Heaven…the Blessed Mother. That type of thinking would lead you to believe that just because people worship a false god that they call “god,” we, therefore, should not call the true God, by that same name…God…because that’s the same title the idolaters use for their god. That is faulty logic. In the same way, the fact that there is a false “queen of heaven,” does not lead to the conclusion that we worship a false goddess when we call Mary the “Queen of Heaven.” Just as the fact that there is a false “god,” does not lead to the conclusion that we worship a false god when we call our Father in Heaven God. 
 
And there is a true Queen of Heaven, which we see quite clearly in Revelation 12:1: “And a great portent appeared in heaven, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars…” So in this passage, we read that there is a woman…she’s in Heaven…and she has a crown on her head. It is the true Queen of Heaven, Mary, the mother of the male child who is to rule the nations. 
 
As Catholics, we do not worship Mary; we honor her, just as Jesus honors her. So there is absolutely nothing wrong, from a scriptural point of view, in calling Mary the Queen of Heaven, and in honoring her just as Jesus honors her.
