Satan knows where your lost keys are

from here
No, the title isn’t the worst name ever for a horror film.  It is the thought that goes through my mind when I read things like Novena [a devotion] to Saint Anthony to Find a Lost Article –The Patron Saint of Lost and Found:

St. Anthony of Padua is invoked thousands (maybe millions!) of times daily to help find items that have been lost. This novena, or nine-day prayer, to find a lost article reminds us as well that the most important goods are spiritual.

NOVENA TO SAINT ANTHONY TO FIND A LOST ARTICLE

St. Anthony, perfect imitator of Jesus, who received from God the special power of restoring lost things, grant that I may find [name the item] which has been lost. At least restore to me peace and tranquility of mind, the loss of which has afflicted me even more than my material loss. To this favor, I ask another of you: that I may always remain in possession of the true good that is God. Let me rather lose all things than lose God, my supreme good. Let me never suffer the loss of my greatest treasure, eternal life with God. Amen.

I mean the title quite seriously.  This Anthony fellow is dead and there is no biblical support that he can hear the prayers of billions of people simultaneously in all their languages and that he then can tell you where to find your keys (or whatever you lost).
Let me break that out for emphasis.  Allegedly, he and other saints can:

• Hear from billions of people at once and know which messages are for them
• Understand all languages
• Have the power to communicate back to you in some way

So having read the Bible through quite a few times I’m pretty skeptical of those claims.  Apparently people think that certain dead people can answer certain types of prayer requests.  It reminds of the line in This is Spinal Tap about St. Hubbins being the patron saint of quality footwear (see the 2:03 mark here).
But guess who does know where your keys are?  Satan and/or his demons.  I think it is much more likely that any prayer to Anthony is being “answered” by Satan, because by praying to the dead you opened yourself up to it.
I encourage people to read the Bible and just go straight to Jesus.  There is one mediator between God and man, and He is Jesus.  Do not pray to Mary or any other human being, dead or alive.  Just stick with any member of the Trinity, or any combination of the three.
