Do all types of Christianity go to heaven according to protestants?

Answer 1

A New Testament perspective:Various "protestants" would give various answers, but strictly from the standpoint of NT scripture, it's clear that not all "Christians" will be saved:

Matthew 7:21-23 - "Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven.

Many will say to Me in that day, 'Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?' And then I will declare to them, 'I never knew you; depart from Me, you who practice lawlessness!'"

As that passage continues, Jesus goes on to further emphasize not only "hearing" His word, but "doing" it, and that many will claim the former yet fail in the latter.

Jesus was also clear on the point that flattering worship based on man's teachings is rejected:

Matthew 15:7-9 - "Hypocrites! Well did Isaiah prophesy about you, saying: 'These people draw near to Me with their mouth, And honor Me with their lips, But their heart is far from Me. And in vain they worship Me, Teaching as doctrines the commandments of men.' "

Furthermore, Jesus told a parable to teach that not all even in His true church would be saved:

Matthew 13:24-30 - Another parable He put forth to them, saying: "The kingdom of heaven is like a man who sowed good seed in his field; but while men slept, his enemy came and sowed tares among the wheat and went his way. But when the grain had sprouted and produced a crop, then the tares also appeared.

So the servants of the owner came and said to him, 'Sir, did you not sow good seed in your field? How then does it have tares?' He said to them, 'An enemy has done this.' The servants said to him, 'Do you want us then to go and gather them up?'

But he said, 'No, lest while you gather up the tares you also uproot the wheat with them. 'Let both grow together until the harvest, and at the time of harvest I will say to the reapers, "First gather together the tares and bind them in bundles to burn them, but gather the wheat into my barn." ' "
