In the past I thought about something, that is that some say they pray to the Virgin Mary, sometimes I have heard her called Our Lady of Guadalupe, or the Lady of such-and-such place. With the doctrine on the Virgin Mary and praying to her I remembered two verses in the Gospel of Matthew that has caused concern. The following verses are as follows
"When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. But he had no union with her until she gave birth to a son. And he gave him the name Jesus." (Matthew 1:24-25 NASB)
" He [Jesus] came to His hometown and began teaching them in their synagogue, so that they were astonished, and said, "Where did this man get this wisdom and these miraculous powers?
"Is not this the carpenter's son? Is not His mother called Mary, and His brothers, James and Joseph and Simon and Judas?
"And His sisters, are they not all with us? Where then did this man get all these things?" (Matthew 13: 54-56 NASB).
By these two verses, we see that Mary had four sons, James, Joseph (Jr.), Simon and Judas and at least two daughters - this comes from the fact that the original Greek is plural - by her husband Joseph. I quoted from the New American Standard Bible (NASB) because it is the most literal translation for English available today.
Through the daughters and the some of Simon, Judas, and Joseph Jr., Mary and Joseph had the opportunity to have descendents. It is uncertain under James because the book of the Acts of the Apostles, a writing credited to Luke, says that he was killed by a sword. I do not know if he married and had children or descendents. The main point is that it is almost 2,000 years since Mary and Joseph had children and the significance is that is very probable for them to have living descendents today.
This leads to one concern for the doctrine to praying to Mary and petitioning her as some Catholic branches do. If she has living descendents, then it means that any who act according to the doctrine about the Virgin Mary, then it would literally be praying to their ancestor. Yet, the Bible clearly shows that the dead cannot hear petitions of prayer and the First Commandment is clear, "You shall have no other gods before me." The ramification for this command is that prayers and petitions can be only directed to the one God and no one else, whether it is angels or saintly men and women.
I did pray to Mary a few times, but then stopped because it was pointless to ask someone who could not hear them if I did them silently in the heart when God could hear them and only He could do anything about the prayers in the first place.
In the end, prayers to Mary or saints in pointless because they can not hear them and God wants us only to pray to Him directly.
