As it was pointed out : "Catholics DO NOT worship Mary. Catholics DO NOT worship saints. We see them as intermediaries."
The trick is to use the intermediaries to replace the Holy Trinity.
An intermediary doesn't replace the entity at the other end of the mediation. If it did, it would cease to be an intermediary.
(THE PASSION OF THERESA MARIA SCHINDLER ON HOLY FRIDAY 2005)
You know, I'm sorry about Terri, too, but I don't go around blasting other people for their alleged idolatry and then comparing her to Jesus in my tagline. Maybe you ought to consider prying that plank out of your tagline, er, eye.
Nobody is replacing the Trinity with Mary or the saints. I have no idea where you get this idea. As has been pointed out numerous times here, we simply ask them to pray for us. That in no way means we are replacing the Trinity for them. I pray to God, and I pray for the saints and the Virgin Mary to pray for me as well. You just continue to show your ignorance and self righteousness.
