This question is going to be a bit of religious nature, but it does contain something gramatical.
Suppose that you believe in the trindade (or the Holy Trinity in English), and that the end of the world, as prophecied in the Revelation, is just coming right now.
So you would be see zillions of angels flying in the sky going up and down all over the world, and o próprio Deus, o próprio Jesus, and o espírito santo would come back to this world once again in some ways (I can't be specific on how they are coming because the notion of trindade is just too mysterious to be describable with my poor knowledges).
Now, the question is, would you say
o próprio Deus, o próprio Jesus, e o espirito santo estão aqui ?
I am asking this question because I heard a guy who I guess is a Catholic or Protestant might have sung a song where he says estão in this kind of situation.
But estão is the third person plural form of estar, and this sounds inconsistent with trindade.
By the way, the song I heard is Anjos de Deus sung by Elizeu Gomes.
Any effort for clarifying on this matter would be really appreciated.
