[St_Thomas_Aquinas]

If their physical, earthly bodies are dead, communication with them is forbidden.

We're not conjuring them up, like the witch of Endor, or engaging in two-way conversation.

We're asking them to pray to God for us.

Rev. 5:8

And when he had taken it, the four living creatures and the twenty-four elders fell down before the Lamb. Each one had a harp and they were holding golden bowls full of incense, which are the prayers of God's people.

It’s irrelevant.

Contacting the dead is contacting the dead.
