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.
As someone who was baptized Catholic, grew up and left the church for a while, and eventually returned, I can tell you that I didn’t really understand the depth of my Catholic faith. It wasn’t until I started listening to Catholic apologetics on the Catholic Answers radio program that I started to better understand everything. I really encourage you to listen in and learn your faith in a deeper way. You can even go to catholic.com , type in any question you have, and find articles, interviews, etc… on the topic. I hope you decide to look into it. I laugh so hard when I see all these non-Catholics here on GAW trying to explain Catholic teaching and theology. Go to catholic.com , listen to Catholic Answers on the radio, and learn from people who REALLY understand the Catholic faith.
And where in the bible does it say 'bible alone' or Sola Scriptura as you seem to believe. Dude, just go to the website I told you about and search any question you have. Go, search 'what does the bible say about speaking to the dead?". You'll get an answer to your question and you will learn what Catholics believe about that. You will actually learn something. I guarantee it. Are you going to do it? or are you going to continue relying on your own interpretation of the scriptures?
