First of all, to answer your challenge, all you have to do is pick up a Catechism of the Catholic Church and look up our Blessed Mother. This book speaks for the Catholic Church more authentically than any of us laity can. **Problem: The Bible is the inherant Word of God. The Catechism of the Catholic church isn’t.

**
Having said that, show me where the Bible says that everything we as Christians need to know about our faith must come only from Sacred Scripture. If this is what you believe, you ought to be able to find a verse from Scripture that backs this up. Can you do this? **I don’t believe everything that is truth is contained in Scripture, but I do believe that everything in the Bible is truth. Think about that.

**
If you can, then I will agree that the Catholic view of Mary is counter to Scripture simply because not all Catholic beliefs about Mary are explicitly mentioned in Scripture. I think this is what you’re getting at.
If you can’t, then I will maintain to you that the Catholic teachings on Mary are not counter to Scripture simply because they aren’t explicitly mentioned. You then will have to acknowledge (even if it is only to yourself) that even those who believe that everything we need to know as Christians must come from the Bible don’t actually believe that every single thing we need to know must come from the Bible. After all, if the Bible doesn’t explicitly call out the doctrine of Sola Scriptura, it must have come from somewhere else…
