Because that is what cults do. If they want you to pray to Mary or any mortal besides Jesus, then they are a cult.
You’ve got it backwards, and I’m sorry about that.
Catholics believe only in Christ as our savior.
We ask Mary and the saints to pray for us, after all their spirits are alive in heaven, right? And they are much closer to Christ there, right?
Please check into upgrading your thoughts here and not believing some of the publications/comics, etc. that you may have been brainwashed with? OK?
