Concerning the fall of Adam and Eve, the Church doctrine is correct. Their fall is our fall, too. We are a community and our community of man gave us a bad start. Concupiscence draws us to choose our own wants above God. That seems to me to be the challenge of the law of the old Covenant: Love God before your wants.
I think the question, "Are most people going to hell?" according to the old law would be yes. With Christ, we have a chance to be washed clean. To Christ, however, is given the judgement. That authority is important. God does things economically, perfectly. Christ judges in the final judgement, because I think the angels lack the capacity to judge, the apostles lack the capacity to judge. It requires I think to judge perfectly, with perfect justice, the infinite wisdom of God and God also fully man is our judge.
All the influences in your life from the simplest of choices and now add all the influences in your environment throughout your lifespan and now add all the influences on in all the generations that led up to you and all the people who impacted you. Now add the judgement in love, your heart and the depth of it. Who else could judge but God? How are justice and mercy brought together? This is the mystery behind hell.
It is not in our capacity to answer this question. Our role is much simpler: to love God, love our neighbor and love ourself in that order. Even that simple role is impossible, I believe, for fallen man without constant divine help. That God keeps us all in existence, atheist and theist alike is a testimony to his love.
This problem of hell, of justice and mercy, I see it spoken to directly by Jesus in the NT. He is the very same Jesus Who will be our Judge:
|And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven. 25 And when they had heard this, the disciples wondered very much, saying: Who then can be saved?
26 And Jesus beholding, said to them: With men this is impossible: but with God all things are possible.
Scripture tells us God is Love; we should strive to cooperate with Him and trust in Him and the divine Mercy He has given us freely when we do not deserve it.
We must trust, because we, ourselves, lack the capacity for perfect judgement and lack the wisdom for mercy so great to understand ll depth the infinite holiness that is His Son, Who was allowed to be mocked, beaten, tortured, and crucified for us, while bearing all our sins..
This is about no small mystery.
The recourse I have to this concern is to pray the Divine Mercy chaplet every day at 3 pm and remember the Passion of Christ.
"Eternal Father, I offer you the Body and Blood, Soul and Divinity, of your dearly beloved Son in atonement for our sins and those of the whole world.
For the sake of His sorrowful passion, have mercy on us and on the whole world."
