You appear to have a slippery view of the Bible.
“Everyone who acknowledges me before others I will acknowledge before my heavenly Father. But whoever denies me before others, I will deny before my heavenly Father.” Matthew 10:32-33
“He who believes and is baptized will be saved; he who does not believe will be condemned.” Mark 16:16
“Fools say in their hearts, ‘There is no God.’” Psalms 14:1
“If we have died with him we shall also live with him; if we persevere we shall also reign with him. But if we deny him he will deny us.” 2nd Timothy 2:11-12
No it is not essential to even be christain to make into heaven.
Let me remind you of the story of the good samaritan.
Think about it this way. If 10 Catholics walk past a dying man in the streets with their noses in the air basking in self rightouesness and let him die. There excuse? we already believe in God, we automatically get into heaven. Some other responses are we dont take care of this scum.
An Atheist feeds the man and takes him to a doctor and pays for his medical bills, and helps him get a job. His response: It was the right thing to do.
Who do you think Jesus rewarded with eternal life?
Faith is nice, but Jesus made it clear good works, compassion, and charity are the most important factors for Salvation. Remember Jesus died for all of our sins, not just Catholics.
“The Lord has redeemed all of us, all of us, with the Blood of Christ: all of us, not just Catholics. Everyone! ‘Father, the atheists?’ Even the atheists. Everyone! And this Blood makes us children of God of the first class. We are created children in the likeness of God and the Blood of Christ has redeemed us all. And we all have a duty to do good. And this commandment for everyone to do good, I think, is a beautiful path towards peace. If we, each doing our own part, if we do good to others, if we meet there, doing good, and we go slowly, gently, little by little, we will make that culture of encounter: We need that so much. We must meet one another doing good. ‘But I don’t believe, Father, I am an atheist!’ But do good: We will meet one another in heaven.” -pope francis
I plead with you to to read the bible,
For I was hungry, and you gave Me something to eat; I was thirsty, and you gave Me something to drink; I was a stranger, and you invited Me in; 36naked, and you clothed Me; I was sick, and you visited Me; I was in prison, and you came to Me.’…
When did we see You sick, or in prison, and come to You?’ 40"The King will answer and say to them, ‘Truly I say to you, to the extent that you did it to one of these brothers of Mine, even the least of them, you did it to Me.’ 41"Then He will also say to those on His left, 'Depart from Me, accursed ones, into the eternal fire which has been prepared for the devil and his angels
, ‘Truly I say to you, to the extent that you did not do it to one of the least of these, you did not do it to Me.’ 46"These will go away into eternal punishment, but the righteous into eternal life."
Jesus clearly is saying that those who do good will be let in to the kingdom of heaven and those who do wicked will be cursed out and thrown into hell.
Blessed be the lord
John 3:16
