“show in the Bible where Mary or any of the saints can be prayed to ... Crickets, etc.”
In Luke Chapter 9 Verse 28 Jesus himself prays to Moses and Elijah (saints) for them to join him and they do on the mountaintop.
In Luke 16, the parable of the rich man and Lazarus, the rich man prays directly to Abraham (saint) to help him out of his torment.
The dead who are “in Christ” (the saints) are not dead and therefore can be communicated/prayed with/to as if they are alive, because they Are alive.
Luke 9:28 says nothing of the sort. He was not praying to either Moses or Elijah, but to the Father. He did go on to converse with Moses and Elijah, who seemed to have physically joined him there on the mountain.
In Luke 16, the rich man has died. So you have a post-death person communicating with another post-death person.
Are those two examples all you’ve got?
I can think of one example of a pre-death human trying to speak with a post-death human: In 1 Samuel 28 a godless King Saul attempts to communicate with Samuel, a practice forbidden by Scripture.
Necromancy is forbidden (see Lev. 19:31, 20:6, 20:27, Deut. 18:10, etc.). 1 Chronicles 10 says that King Saul died in part because he sought to communicate with post-death humans.
In any case, there is no example of any person — pre-death or post-death — receiving any kind of help from a post-death “saint.”
In Luke Chapter 9 Verse 28 Jesus himself prays to Moses and Elijah (saints) for them to join him and they do on the mountaintop.
The verse says no such thing. All it says as that HE went up to pray. It says NOTHING about who He was praying TO.
Luke 9:28 Now about eight days after these sayings he took with him Peter and John and James and went up on the mountain to pray.
Do you seriously expect believers to believe that Jesus the Creator, was praying to Moses and Elijah the created?
Talk about heresy.
