Yes, Mary was a faithful servant to God Because she said YES to Him. But NO, she didn't simply act as a vessel for God's son. You're going to tell me that Mary was simply a vessel and after she gave birth and then she had no use? lol. Do you understand how holy someone would have to be to carry and then give birth to the Son of God!? You do understand that, through a process called Microchimerism, mothers carry their children's cells in their blood and other tissues even after birth. That would mean that Mary had Jesus' (God's) DNA in her. And to clear something up for you Prots. for the 5,000th time, lol, we do not worship Mary. Worship is reserved for God alone. We venerate her, hold her in high regard, respect the spiritual authority she has, and respect that she is Jesus' Mother. The same goes for the Saints in heaven. It's no different than when people ask one another, "Hey, I'm going through a time or I'm dealing with this thing, could you pray for me?" Seriously, if you actually want to learn about the Catholic faith, go to catholic.com and type in any question you have. You are pretty much guaranteed to find an article or discussion from actual Catholic apologists with an answer to your question.
