According to the Catechism the Trinity has only one substance while being expressed in three persons.
Well that is what I tried to say…three distinct persons, one substance. I used the word ‘identity’ in place of distinct persons…and they are perfectly united in ONE GOD totally indwelling within each other. i found this statement of belief helpful:
ATHANASIan CREED:
*Now this is the catholic faith: We worship one God in trinity and the Trinity in unity, neither confusing the persons nor dividing the divine being.
For the Father is one person, the Son is another, and the Spirit is still another.
But the deity of the Father, Son, and Holy Spirit is one, equal in glory, coeternal in majesty.
What the Father is, the Son is, and so is the Holy Spirit.
Uncreated is the Father; uncreated is the Son; uncreated is the Spirit.
The Father is infinite; the Son is infinite; the Holy Spirit is infinite.
Eternal is the Father; eternal is the Son; eternal is the Spirit:
And yet there are not three eternal beings, but one who is eternal;
as there are not three uncreated and unlimited beings, but one who is uncreated and unlimited.
Almighty is the Father; almighty is the Son; almighty is the Spirit:
And yet there are not three almighty beings, but one who is almighty.
Thus the Father is God; the Son is God; the Holy Spirit is God:
And yet there are not three gods, but one God.
Thus the Father is Lord; the Son is Lord; the Holy Spirit is Lord:
And yet there are not three lords, but one Lord.
As Christian truth compels us to acknowledge each distinct person as God and Lord, so catholic religion forbids us to say that there are three gods or lords.*…
And lately I see so much on TV about being united in a false way under human doctrines that I think this is a Divine attribute we need to honor and put our faith in and desire for mankind.
But this is a unity of Three distinct persons joined in full union as One God. Their substance I believe is Holiness and all that Holiness means…love, mercy perfect justice, purity, perfect humility, etc…
But pardon me if I need to ponder the idea of three distinct persons all having the same substance and existing as One…in other words, what makes them distinct persons if their substance if the same? How do you explain that?
Does it have to do with relationship? With action? If you can help me with that I wouldbe grateful.
