Just stumbled onto this thread now, but I thought I might be able to clarify at least what the basii (basises? bases?) for various beliefs are from Biblical texts. The ones already presented were very good, but I have a few to add. The following is in support of the idea that Christ is the only way to Heaven:
Matthew 11:27 “All things are deivered unto me of my Father: and no man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal him;”
John 20:31 “But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.”
John 3:5-6 “Jesus answered, ‘Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is Spirit.’”
John 3:14-16 “And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: That whosoever believeth in him should not perish, but have eternal life. For God so loved the world that he gave his only begotten Son, that whosoever believeth in him should not perish, but have eternal life.”
An important point about sin and faith is presented here as well:
Romans 3:23-4 “For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus:”
Romans 3:27-8 “Where is boasting then? It is excluded. By what law? of works? Nay, but by the law of faith. Therefore we conclude that a man is justified by faith without the deeds of the law.”
While this seems to preclude the idea that doing good things is what gets you into Heaven, I would draw a distinction between doing good things and being a good person. Paul also mentions elsewhere that faith without works is dead; i.e., as I think someone mentioned, you show that you have faith by doing what a person that has faith would, or should, do. (Although even that begs the question: if I have faith, then I’m supposed to do what I would do?) Maybe it would just be easier to say, a person who has faith should do what we generally accept to be God’s will for us to do, and thus a person shows he has faith by practicing it.
In support of the idea that what you know does matter:
Matthew 11:21-24: “Woe unto thee, Chorazin! woe unto thee, Bethsaida! for if the mighty works, which were done in you, had been done in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. But I say unto you, It shall be more tolerable for Tyre and Sidon at the day of judgment, that for you.”
That really says a lot, IMO: while it not only implies that what you know matters, that also seems to imply that God could have done something more to save Tyre and Sidon–in effect, while that doesn’t necessarily make God responsible for their destruction (they may have had free will to obey/disobey and chosen to disobey), it’s possible that God could have made their salvation happen (without violating free will) if He’d chosen to.
This quote was already mentioned, but it seems to point out that the state of a person’s heart, and not his knowledge of God’s law, is what determines his salvation:
Romans 2:14-15 “For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: Which show the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another; )”
I think this would also work well with the “Jesus is love” argument mentioned before: only by knowing/believing/having faith in Jesus can one be saved, and one may know Jesus in having a good heart even if one does not know Him by name, so it is thus possible for those who don’t know Jesus by name to be saved. One issue some might take with this, however, is that it seems arbitrary: some people “by nature” obey the law, and others don’t… but it’s not clearly explained how this would fit into the model of free will, which other parts of the Bible seem to suggest that salvation is clearly contingent on.
(BTW, just for argument, the book of James is sometimes construed to be disagreeing with the “faith-only” basis of salvation; this quote might represent that: James 1:26-27 “If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man’s religion is vain. Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world.”)
I thought I’d add that I personally don’t accept the idea of a stratified Heaven or hell, since it came up earlier. As I see it, while Heaven and hell may seem like reward and retribution, respectively, those are not their actual purpose but just ancillary benefits: Heaven is the place where those that obey God belong, and thus believers are taken there because they belong there, not because God is trying to bribe them (although there are texts one could quote which seem to suggest otherwise; however, I think these can be dealt with in the context of the entire Gospel message). Heaven is where God is and where those justified to Him belong; it’s merely a perk that, yeah, it’s full of pleasure that lasts for eternity (this idea is supported by Biblical reference as well). Hell, on the other hand, is where those who by their choice of sin have decided to reject God belong: away from Him. I don’t believe in the eternal-suffering hell of some preacher’s imaginations, but that hell is the sinful world that exists today and which God will eliminate post-judgment.
As for who will make it where, here’s something to think about: to be un-justified, one must be sinful. Parts of the Bible suggest that sin is the legacy of humanity and that every human is born into it, but I find an inconsistency in that because Jesus Christ is stated to have lived a life without sin, and yet to have been born of a human being. This fits with what I think is a better definition of sin: the willful disobedience of God (or the willful decision to do that which you know is wrong, if not in the context of theology). If you accept this, that leads to an interesting problem: what happens, not just to people who don’t know Christ, but to babies who die moments after birth? Since they never had the opportunity to do anything, they can’t be considered righteous (since righteousness, I think, requires willful activity), but they can’t be sinners either since they never had the opportunity to sin. They would be blameless, and as such, don’t deserve to be separated from God, right?
But does that mean that anyone who died without having the opportunity to sin should go to Heaven, since it’s certainly plausible that a substantial number of those children would not only have been sinners but have been unrepentant ones if they’d lived? In other words, does dying before you have the opportunity to sin award you a “Get into Heaven free” card? And if so, wouldn’t that seem to suggest that the best thing we could possibly do for those about to enter the world is to kill them the moment they do, thereby guaranteeing them eternal bliss?
Anyway, it’s complicated (and I’m sure there’s a lot of points that I missed), but even answering the simplest parts of these questions creates many more.
