Persona = Person in common language borgite. The Father, Son, and Holy Spirit are not identical with one another nor separate from one another but simply three distinct persons (personae) of one substance (una substantia).
The Christian view of the Trinity is often described as a view of one God existing in three distinct hypostases/personae/persons. The Latin “persona” is not the same as the English “person” but is a broader term that includes the meaning of the English “persona.”
I am not going to waste my time further to provide definitions in greater detail. They can be found by a reasonable search of the internet in regards to their use in Trinitarian doctrine.
It is really stupid to think you can declare something null and void based upon your failure to do your own homework.
As I said, if these creeds can't handle the English language, then they are pointless and meaningless.
