“So is eating meat, drinking wine, and kissing one’s children. Point?”
That is a frivolous response.
“If you ask me to pray for you, is it my body that does it or my soul? Does my soul die when my body dies? If you think I have an everlasting soul and its my soul that does the praying, isn’t it then consistent to treat all souls alike, whether or not the body is dead?”
I believe this is a serious response and presents an interesting argument.
If valid it would cover praying for deceased people, but not to them.
Why? Catholics don't pray to ask passed souls in the belief that those souls have special powers to answer prayers, but rather for the same reason they confer with souls still present in the body, when asking for them to pray for them. Why? Because some passed souls, such as a persecuted Saint or your mother, might understand your situation better than the person next to you at Mass. I think some Catholics take this to extreme and even past extreme. If and when they pray to a passed soul in the same way they pray to God, then they are in error.
