Is it not true when a person prays they are conversing with something that is invisible to the eye?
I happen to be one of those verbal people who often talks to people who are not present. This is fortunate, most of the time.

I do not consider my rantings “prayer”. There are many believers who have visible experiences of saints, personally, I have not. For me, conversing or praying to a saint would be invisible, just like telling off my boss while I am changing the oil in the truck would be done while he is not visible.
Do any other writers use this event as a description or teaching on prayer?
Oh, I am sure they do. Peter thought it was a sanctified experience, and that they should build booths on the spot. However, the reason it was brought up in this context was to demonstrate to you that people who have discarded the veil of flesh are awake, alive, and present in the communion of saints, and can interact with people on earth.
You mean when you are in a deep sleep you can hear conservations of your next door neighbors in a state of sleep?
I can’t say that has happened, but I can surely attest that when I leave the TV on it interferes with my sleep because it impinges upon my psyche.
Would you happen to have an example of this? I wasn’t aware that when a catholic prays to a saint that saint is able to communicate back to the person here and is aware of the circumstances.
There are a number of examples I could give you of this, ja4. I have considered it many times. It seems to me that if you studied Mary and the lives of the saints you would have a much richer understanding. However, since I know you already consider all these to be appearances of evil spirits,a nd not from God, I think I will refrain.
Does this same kind of thing happen today for catholics when they pray to saints?
Daily. However, you would reject these experiences as “speculations of men” becauae they are not listed in your bible.
Then this is really not about prayer but something else entirely.
I think it is a semantics problem, ja4. You believe that we should not “pray” to anyone but God. It is an “elderly” use of the word, and I think misleading. It would be more clear to say that we ask them for intercession. I don’t know that Jesus asked Moses and Elijah for intercession.
Have you read the Glories of Mary? There is also another devotional work by De Mont or something like this. These works are absolutely amazing in what they say. Are you open to discuss them?
Yes. Frankly I find them quite beyond me. I don’t think it would be useful to discuss them with me. I don’t think it would be useful for you to discuss them at all. It is clear that you already have your mind made up that they are pagan intrusions into the faith. I think your motive for discussing them is to try to pull Catholics away from their faith, and encourage them to join a Bible Church. you have already stated that the only way to grow in Christ is to read the Bible, so that pretty much leaves out all Catholic devotionals.
