What is the verb ending of われん mean?


I am reading the Fullmetal Alchemist manga and came across the following in
the first volume:

> 祈り信じよ
>
> されば救われん

The subtitles of the
[anime](https://en.wikipedia.org/wiki/Fullmetal_Alchemist_%28anime%29)
translate this to be:

> "Pray and you shall be saved."

The translation work on [Viking
Anime](http://z7.invisionfree.com/Viking_Anime/index.php?showtopic=24&view=findpost&p=13289803)
has this:

> "Believe in your prayers, and you can be saved."

The first part is easy (about the prayers), but the part I can't figure out is
the "われん" ending. The base verb is 救う, so is 救われん a contraction? If so, of
what verb ending?




救われん is made of 救われる and the archaic suffix ん, which came out of む. む・ん had
similar roles to よう・おう today; that is to say, 救われん in modern style would be
救われよう or 救われるだろう. It is not related to the ん that comes out of ぬ, which is a
strong or dialectal way of stating a negative.

Additionally, as chocolate says in the comments, 祈り信じよ means 'Pray and
believe', rather than 'Believe in your prayers.' Accordingly, the full phrase
literally means 'Pray and believe, that you might be saved.' In more modern
Japanese, the phrase is 祈って信じなさい。そうであれば、救われよう。
