They have their own religion.
Homos as Priests and now this - unbelief and you're still "saved" - totally UnBiblical.
Read the John 3 verses that you posted more carefully.
"He that believeth on him is not condemned: but he that believeth not is condemned already"
This doesn't say anything about those who are not aware of Christ, only those who either : know Christ and believe; know Christ and do NOT believe.
What about those who never HEARD about Christ? Your way condemns THEM to hell, as well. You are being "unbiblical". Here is what the Scriptures says about such people:
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; Because that which may be known of God is manifest in them; for God hath shewed [it] unto them. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, [even] his eternal power and Godhead; so that they are without excuse: Because that, when they knew God, they glorified [him] not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. (Romans 1:18-21)
Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things. (Romans 2:1)
For not the hearers of the law [are] just before God, but the doers of the law shall be justified. 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 shew 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. In the day when God shall judge the secrets of men by Jesus Christ according to my gospel. Romans 2:13-16)
It appears that it is normative for a person to accept Jesus Christ as their Lord and Savior as the ordinary way to taking the step to become saved. However, Paul recognizes that God even writes His Law on those people's heart who do NOT know about Christ - and they CAN and DO obey this Law. God will judge us according to the Gospel that Jesus gave us - to love the Creator of the Universe and our neighbor as ourselves. If God desires that all men be saved, it is a contradiction to say that He condemns people who never even HEARD of Christ.
This is why reading the Scripture is so important, rather than reading one's own theology into it. As a result, you missed part of the Gospel.

Here we go again... What's truly CONTRA-biblical is your skill at passing judgment on the Church founded on Peter.
Which version of the Holy Spirit inspires YOUR church? We in the Catholic Church are still using version 1.0, whereas yours is, well, just a pirated, 20,000th-generation copy.
I wouldn't be placing bets on who enters heaven and who doesn't. God has a way of embarrassing the presumptuous.
