The Catholic church teaches that Mary is the co-mediator to whom we can entrust all our cares and petitions (Catechism 968-970, 2677).

There is NO co-mediator, NO co-redemptrix.

“For there is ONE God
and one mediator between God and men,
the man Christ Jesus,
who gave Himself as a ransom for all men…”
1 Timothy 2:5-6

There was no apparition of the “blessed virgin.” The mother of Jesus Christ was a flesh and blood human being like you and me. She died and is in a place called heaven. She is NOT “omnipotent,” nor is she “omnipresent,” those are attributes of God alone. She does not appear to people, and when people see apparitions, they are actually seeing fallen angels and demons intending to divert worship away from Jesus Christ. To wear an image in obedience to an apparition or to bow before a statue, is the essence of idolatry and is clearly forbidden by the Word of God. In fact, rather than convey a protection, an image or charm can actually bring a curse. Get rid of anything that you put your trust in, get rid of any “religious” object that you think will bring you favor. They won’t. They are inanimate objects that cannot see, cannot hear, cannot speak, cannot protect, nor can they gain you any favor from any one.

There is only “ONE MEDIATOR….”

But Catholics say they don’t worship Mary. No? Here is one of their favorite prayers chock full of Mary worship…..

Morning Consecration to Mary

My Queen, My Mother, I offer
myself entirely to thee.
And to show my devotion to thee,
I offer thee this day, my eyes,
my ears, my mouth, my heart,
my whole being without reserve.
Wherefore, good Mother, as I am thine own,
keep me, guard me as thy property and possession.
Amen.

Nice words. But they’re heresy.
