Do different Christian denominations think each other will be saved?

Question

There're lots of Christian denominations out there. I'm wondering if each of them have an official answer to "if the Second Coming were today, believers of [other denomination] will/will not be saved". I'm interested in both the bigger denominations (Catholicism, Anglicanism, Methodism ...) and the smaller ones (Mormonism, Jehovah's Witnesses ...). A full list is likely impractical, but partial tables are also good.

I haven't been able to find anything about this except scattered statements such as "[Jehovah's Witnesses] consider secular society to be morally corrupt and under the influence of Satan, and most limit their social interaction with non-Witnesses" which implies that this denomination will say answer the question with "no" for every other denomination. It's possible I am searching for the wrong terms though, so I am asking this question.

Edit: some clarifications per the comments. I'm only interested in the official doctrine, not the beliefs of individuals. A denomination thinks the other will be "saved" if members of the other denomination are treated the same as members of the original denomination at the Second Coming. It is "not saved" if they are treated the same as unbelievers (i.e. non-Christians). For everything else in between, it's "partial" (i.e. part yes, part no).

Answer 1

From a conservative Baptist perspective, which I no longer am but with which I am very familiar, the only people who are 'saved' are those who, in acknowledgement of their sin, have relinquished faith in any and every other thing including good works and religious activity and personally assign their entire hope to the sacrificial death of Christ for the atonement of their sin and to the resurrection of Christ for the imputation of Christ's righteousness to their account.

CB's believe that 'salvation' is an intensely personal and not a corporate affair and is not imparted by a creed or a baptism, nor conferred by a priest or any ritual.

CB's believe that this is what constitutes being 'born again' or 'born from above' and that it is a permanent translation from death to life. CB's believe that sitting under accurate biblical teaching (especially about the person of Christ) certainly increases the likelihood that a person might respond (and most Baptist churches seem to believe that they teach the most accurately...or maybe that's just all churches) but that church attendance, bible reading, denominational adherence, sacramental participation, and theological training guarantee nothing.

In short, CB's believe that only those who are born again are actually Christian and are saved, regardless of denomination or self-designation.

Answer 2

From the Seventh-day Adventist perspective, yes, people of other faiths will be saved. Jesus said clearly that he has his sheep in other folds.

It is wrong for any Bible believer to judge any other human, as we are expressly admonished not to. Judgement belongs to God, and it is not for us to include or exclude anyone. Any attempting to do so need to be very careful to rather point to the peril to which sin exposes you and to do so in as non-judgemental a fashion as possible. This can be rather difficult in practice, but it helps to think of all souls as infinitely valuable.

It is only in the light of eternity that the true value of a human soul can be appreciated.

I suspect most Protestant faiths hold this position as it is almost a defining point of Protestantism which rose against the Papal claim to hold the keys to heaven and that only through her could salvation be granted.
