I think the Scripture means you should content yourself with the living and pray only to God.
Why do you need to pray to anyone other than God?
What does He lack for you?
If we are all One, who should be content being apart? Forget part of the Body of Christ? Why? For what purpose?
Are the dead dead to us or are we all alive in Christ?
Is there some virtue in minimalism that I'm missing?
Maybe we are crossing lines on "communion." By communion I mean we share, we are part of the same mystical Body of Christ. We are One. Saints on earth, Saints in Heaven. Christ as our head.
Is this not part of Calvinist theology?
