I think you meant to say "Person"; the Trinity does not have parts.No, really I didn't...Humans are persons...Sinners are persons...
Bible says God is Spirit...The Holy Spirit I would think is not a person in the human sense of the word...
All I know is that there are three of 'em...
A human has a body, a soul and a spirit...Gen 1:26 And God said, Let us make man in our image, after our likeness:
We don't even know if we will appear as humans in heaven...
But I don't dwell on it...When we meet Jesus, we will appear as He is...
If the being you worship has parts according to its essence, then that being is a created being, because composite beings (i.e. beings having parts) have causes. Their parts are their causes, and that which makes their parts be
one composite being is also a cause. And if you are worshipping a created being, then you are violating the First Commandment. Therefore, if you are worshipping a being that has parts according to its essence, then you are violating the First Commandment.
