No, we're not, as explained at length above. How does "over all communications addressed to me" equal "all things". I read my mail. I don't and can't read everyone's mail. I get phone calls when people dial my number. I don't get all phone calls.
And even if were, God forbid, to get everyone's mail, there could be other things of which I was not aware.
And finally, it is by God's grace sustaining my alleged brain that I can read my mail. If it were God's will that I could read everyone's mail (as apportionment no doubt, for my misuses of communication) then He could accomplish it it me.
So the contention that a Saint can hear and pass on all prayers addressed to him or her in no way reasonably implies that the saint is aware of everything or can do everything.
I disagree, MD, to the extent that anyone is saying the Pio has perfect, situational awareness. That is omniscience.
To the extent that any deceased saint’s awareness is first filtered through God, then that is God having perfect situational awareness, and I already believe in that.
Which raises the key point: If the saint’s situational awareness is filtered through God in the first place, then it makes more sense to go ahead and use the direct route to God.
Pray to God.
If you desire, then, to ask God to pass a message to a loved one, then feel free to do so.
