Be careful not to set up a false dichotomy here. Mary, pregnant, is carrying Jesus, the Word of God. Pretty clearly this is a package deal, not an either/or.
And if you go to the Basilica of Guadalupe (or any other Catholic church) you can't help but notice that the Mass is drenched with Scripture: not only the Epistle, the Old Testament lesson, the Psalm, and the Gospel at EVERY Sunday Mass, but in fact all the prayers are either straight Scripture or based on Scripture.
So if Mary got them into the Church, she got them into the Word.
It's not "pretty clear" and I strongly believe this is an absolutely wrong interpretation. To say it's a "package deal" is nothing more that a Co-Redemptix view and assumes God was incapable of bringing our Lord Jesus into the world any other way; that God needed help to bring about the birth of Christ. I would not make that "assumption". I think God can be a bit creative when He wants to be.
There is nothing in scripture that parades Mary around after the death of Christ. The apostles don't even mention her. Clearly if Mary was so significant to attracting followers then one wonders why there wasn't more history about a church that she started.

How many Catholic churches have you been in overseas? I have been to quite a few. Nothing personal but I find Catholic churches in Third World countries border on the occult.
