哪位高手帮我翻译下吧··拜托了··

如果爱情是真爱，如果爱情是我们的信仰，不忠无法与之较量。任何的不忠都是信仰的欲望。

什么是eaual和augt

难道是古英语咩- -||

原文应该是这样的：
In Love, if Love be Love, if Love be ours,
In Love, if Love be Love, if Love be ours,
Faith and unfaith can ne'er be equal powers:
Unfaith in aught is want of faith in all.

It is the little rift within the flute,
That by and by will make the music mute,
And ever widening slowly silence all.

The little rift within the lover's lute,
Or little pitted speck in garner'd fruit,
That rotting inward slowly moulders all.

It is not worth the keeping: Let it go:
But shall it? answer, darling, answer, no.
And trust me not at all or all in all.

eaual应为equal，但是不知道aught是什么意思，最后一句最难翻译。
如果爱是爱，如果爱是我们的。那么，信念和？的力量将不会是相等的……
Sorry，I can't help you。
