Well, "they" is gender-neutral pronoun as well as being a pluralizing one. I didn't know whether or not she was male or female, and decided that a gender-neutral pronoun was more appropriate than "it". 
I suppose that Hebrew "הוא" or "hu" was used to denote authority as well as gender. Which is why it is presumed that all angels are male and that God is a He.
