What do you think Catholics ask Mary to do for them?
Let’s start with your level of knowledge, first.
You don't believe what Jesus Christ Himself says and the issue is my level of knowledge?
It's Ok, we'll be praying for you and if you're actually seeking Jesus Christ rather than the usual Self Alone garbage you'll start to understand that Christ is Truth.
Once you accept that you can begin to understand other things instead of revising and reinterpreting what others believe to fit into your preconceptions.
