I have one more thing. in the comment about praying to Saints and the parable about Lazarus, the gulf was between Lazarus and the rich man. Praying to saints in order to ask for their intercession is not the same as trying to contact the dead and have them speak to us as in the occult. WE are not trying to contact the dead and we are sending our prayers to saints how are a live in heaven for their help and intercession. I think this needs to be clarified.
You are correct about that scripture. it proves nothing either way. However we later see Abraham’s reluctance to send somebody from heaven to living brothers of the rich man; and he pointed them to pay attention to the holy scriptures.
27 So the rich man said, ‘Then I beg you, father – send Lazarus to my father’s house 28 (for I have five brothers) to warn them so that they don’t come into this place of torment.’ 29 But Abraham said, ‘They have Moses and the prophets; they must respond to them.’
But I will quote you the example of King Saul who wanted a dead saintly man to give him advice:-
3 Now Samuel was dead, and all Israel had mourned for him and buried him in his own town of Ramah. Saul had expelled the mediums and spiritists from the land.
4 The Philistines assembled and came and set up camp at Shunem, while Saul gathered all Israel and set up camp at Gilboa. 5 When Saul saw the Philistine army, he was afraid; terror filled his heart. 6 He inquired of the LORD, but the LORD did not answer him by dreams or Urim or prophets. 7 Saul then said to his attendants, “Find me a woman who is a medium, so I may go and inquire of her.”
“There is one in Endor,” they said.
8 So Saul disguised himself, putting on other clothes, and at night he and two men went to the woman. “Consult a spirit for me,” he said, “and bring up for me the one I name.”
9 But the woman said to him, “Surely you know what Saul has done. He has cut off the mediums and spiritists from the land. Why have you set a trap for my life to bring about my death?”
10 Saul swore to her by the LORD, “As surely as the LORD lives, you will not be punished for this.”
11 Then the woman asked, “Whom shall I bring up for you?”
“Bring up Samuel,” he said.
12 When the woman saw Samuel, she cried out at the top of her voice and said to Saul, “Why have you deceived me? You are Saul!”
13 The king said to her, “Don’t be afraid. What do you see?”
The woman said, “I see a ghostly figure[a] coming up out of the earth.”
14 “What does he look like?” he asked.
“An old man wearing a robe is coming up,” she said.
Then Saul knew it was Samuel, and he bowed down and prostrated himself with his face to the ground.
15 Samuel said to Saul, “Why have you disturbed me by bringing me up?”
Please note the final line. Samuel was furious to have been disturbed, like a sleeper being rudely awakened. The fact of whether a medium was used is immaterial. Contact with a dead person, however saintly, was proscribed,
