Good to hear from you,

I would be careful about the body soul and spirit thing. It's a pointer but not a perfect analogy, because we are talking about three different persons within the trinity..but I will say we have things that are in a sense multiple and then one in another sense. Say three members but one family, multiple musicians but one piece of music, multiple body parts but one person. Of course none of it is a perfect analogy but even in our world it is not weird for things to be multiple in a sense and one in another sense.
