Do you ever worry about being unwelcome at Heaven’s gates for misbehavior? Is “singing too loud” cause for exclusion?

Here’s a lovely little poem of Emily Dickinson that asks, “is there a place for me in Heaven, even if I’m not exactly what you had in mind? Can I have a second chance? If our roles were switched,  I’d let you in!”

Why – do they shut Me out of Heaven?

Why – do they shut Me out of Heaven? 
Did I sing – too loud?
But – I can say a little “minor”
Timid as a Bird!

Wouldn’t the Angels try me –
Just – once – more –
Just – see – if I troubled them –
But don’t – shut the door!

Oh, if I – were the Gentleman
In the “White Robe” –
And they – were the little Hand – that knocked –
Could – I – forbid?
F268 (1861)  248

Aaron Copland sets this text in his vocal song cycle, 12 poems of Emily Dickinson (1950).  You can listen to a lovely recording by clicking here. (this text is the third song,  begins at the 5:30 mark)

The question I’m left with is: Who are “they” in the first and penultimate line? I think of the admonition to “Judge not, lest ye be not judged” and wish for a Heaven where God is only as just as necessary and as merciful as possible. And doesn’t mind my loud singing.
