I read your answer and I thought it was good Catholic advice until I stumbled upon this statement.
They can never get to heaven? Where would you find that within Catholic teachings?
It is kind of like Jews thinking they are God’s chosen people. They are. God revealed Himself to Jews, or through them, in particular. Salvation is of the Jews, but for everyone.
Jesus the Jew told his apostles to go to all the nations of the world and preach the good news of repentance for forgivness of sins. God’s mercy is for all. It comes through the revelation of God given through the Jews.
Who is the God of the Jews? He reveals Himself to them as existance itself. I am that I am. That is who He is. When Moses asked God who was sending him to the Egyptians to release the Jews from slavery, Moses asked who he should tell the Egyptians was giving them this command. God told Him who He is. I am.
But apart from who God is, what is He like? He revealed things about His nature to the Jews throughout salvation history, not all at once, but from time to time, more and more.
Why are Jews hated? The Jews are responsible for bringing salvation to mankind. The hatred and attempt to destroy them did not begin in the 1930s in Germany. Read about Queen Esther.
Look at the secular world today. Why are Christians hated by the world? Jesus says of His Church that we would be a sign of contradiction to the world. We would be hated, because He was hated. Sounds familiar.
Jews are resented. Those Jews think they are so special and better than everyone else, because they think they are God’s chosen. But it is true. They are. Their religion is true. Others are false. God revealed Himself to this people set apart for His purpose.
Now the Catholic Church thinks it has a monopoly on docttinal truth. That might offend some people. But what if it is true?
Would that mean that only Catholics can attain heaven, eternal union with God? It seems that there would need to be some connection to divinely revealed truth to find God. But what is it?
Can you be connected and not know and acknowledge it? Maybe!
God revealed Himself in the Old Testament as existance. In the New Testament He revealed Himself as love. Is this a one or the other proposition? Or, are existance and love two perfections of the same Being?
Saint John the Evangelist tells us in His epistle that God is love and everyone who loves is of God. He was a cousin of Jesus, another Jew.
The human intellect does not figure this stuff out. The Jews did not discover God. He revealed Himself to them.
The Book of Genesis, of the Jews, tells us that God made mankind in His image and likeness. It does not say God made Jews or Catholics in His image and likeness. If beings are alike, like one another, they do the same things, they share by their natures in some likeness, some like qualities or attributes.
God is love. God loves. If you love you are of God and share or participate in the divine nature, by likeness.
Do Catholics have a monopoly on love? They do proclaim that it is divinely revealed truth and that you can not get to heaven, your eternal destiny, unless you love.
So I guess that is the question for all, Jew and Greek and African and all, each one of us.
Do you love?
Whatever love is, it is always directed to the other, its object. Love gives love to love. There is a trinity there. Existance gives existance. You are given existance. You received it. You do not have a choice in the matter. You do have a choice in whether or not to love.
In order for us to love (get to heaven) we have to know how, know the way. Someone has to show me. A child grows up in a family and belongs to the family, but is also taught how to be part of the family, behave in the family.
This is what the truths of the Church teach us, but we do not always do it whatever religion we have.
