Since when is it a loss to not be speaking with the dead?
Do you ever speak to someone you love who has passed away?
If so, would it be a loss to not have this?
If not, would it be a gain to have it?
I think (some) Protestants teach we are in a kind of sleep when we die. Catholics do not.
From the Catechism:
62 "We believe in the communion of all the faithful of Christ, those who are pilgrims on earth, the dead who are being purified, and the blessed in heaven, all together forming one Church; and we believe that in this communion, the merciful love of God and his saints is always [attentive] to our prayers"
