It might lead to someone suggesting that Mary had other children (Jesus had half-brothers and possibly half-sisters), was impure and needed the Sacrifice on the cross just like the rest of us and should receive no worship, adoration or special attention from the rest of us. Just like I don't pray to or adore Lazarus or Nicodemus or any of the other characters in Jesus' life. So NO to any honest discussion or they may get sad.
But the question does arise...if beloved Mary (and she is by everyone who is Christian) is spotless...why do we need Jesus?
It might lead to someone suggesting that Mary had other children (Jesus had half-brothers and possibly half-sisters)...Such famous children of such a famous mother have names, right? Tell us there names, can you? And their descendants, they must all be very proud of their lineage, you must know the names of some of the descendants of these so famous children, right?
I don’t pray to or adore Lazarus or Nicodemus or any of the other characters in Jesus’ life.
Mary was not just another character in Jesus’ life. She was the mother of God. Get it? The mother of our Lord. Not only that, but the faithful from the 1st Century forward considered her very special, and not “just another character in Jesus’ life”.
