When you are surrounded by people you are related to or friendly with, whom you love but who are not Christians in any sense that the Church would recognise, you have a problem.
Many sages have told us to leave the question of who is saved or not to God. Our Saviour told us the Way is narrow and few find it.
It is a horrible and disturbing thought that someone you love might be deserving of hell (by default, because they didn't take the Lord up on His offer of Grace, but remained good people in the humanist sense).
As the prayer says, 'O Giver of Light, who makes the sun shine upon the righteous and the wicked...' Who are the wicked? Are my dear ones living and dead wicked and in what sense?
God bless you
