Judith where in the bible does it talk about the communion of saints?
As a failed Catholic who once taught a catechism class (do I remember that correctly?) I am quite certain that you already know the answer to that question. Therefore, I would call it another "trick question." A trick question is one that YOU know the answer to, you just want an opportunity to propagandize.
I am certain that you are aware that Catholics do NOT limit their beliefs to narrow interpretations of questionable translations of scripture.
Luke 20
34Jesus replied, “The people of this age marry and are given in marriage. 35But those who are considered worthy of taking part in that age and in the resurrection from the dead will neither marry nor be given in marriage, 36and they can no longer die; for they are like the angels. They are God’s children, since they are children of the resurrection. 37But in the account of the bush, even Moses showed that the dead rise, for he calls the Lord ‘the God of Abraham, and the God of Isaac, and the God of Jacob.’[c] 38He is not the God of the dead, but of the living, for to him all are alive.”
