This is what the "spirit" said to the young man involved in this account.
I greatly desire that a church be built in my honor,
in which I will show my love, compassion, and protection. I am your Mother full of mercy and love for you and all those
who love Me, trust in Me, and have recourse to Me
. I will hear their complaints and I will comfort their affliction and their sufferings. So that I might show all My love, go now to the bishop in Mexico City and tell him that I am sending you to make known to him the
great desire I have to see a church dedicated to me built here." Read more: http://www.ewtn.com/saintsholy/saints/O/ourladyofguadalupe.asp#ixzz3VuhToJg1
If Mary always points to Christ as catholics claim then you can be rest assured, this did not come from Mary.
Would Mary request, even greatly desire, a church to built in her honor??
Again, what we see here is another aspect of the worship of Mary and almost deification of Mary.
