Is "one God in three Persons" accurate?

Yes. "One God in Three Persons" is the official and most accurate way to describe the Holy Trinity in Coptic Orthodox theology.
1. "One God" = One Being (Essence)
When we say "One God," we are talking about the Nature or Being (in Coptic/Greek: Essence or Ousia —).
- There is only one Divine Being.
- There is only one "God-ness."
- If they were three separate beings, they would be "divided," and we would have three gods (Polytheism). We reject this.
2. "Three Persons" = Three Realities (Hypostases)
When we say "Three Persons," we are talking about Who God is.
- The Father is not the Son.
- The Son is not the Holy Spirit.
- The Holy Spirit is not the Father.
They are not just "titles" or "jobs" that one person switches between (like a man being a father, a son, and a worker). That would be a heresy called Sabellianism or Modalism. We believe they are three distinct and eternal Persons who have always existed together.
3. How they are One and Three at the same time
The core of the mystery is that the Three Persons share the One Being perfectly.
- They are "united without confusion and are distinct without separation."
- They are "numbered" (we can count Three Persons), but the number does not "divide" them into separate parts. Each Person possesses the entire Divine Being. The Father is the whole God, the Son is the whole God, and the Holy Spirit is the whole God.
Why "Being" and "Person" are different:
- Being (What): If you ask "WHAT is that?" the answer is God.
- Person (Who): If you ask "WHO is acting?" the answer is The Father, The Son, or The Holy Spirit.
Putting it all together for Acts 2:
When you read about the Father glorifying the Son:
- Identity (Persons): The Person of the Father is honoring the Person of His Son. They are truly distinct Persons; they love each other and speak to each other.
- Unity (Being): The power that glorifies them, the glory itself, and the Godhead they possess are One.
So, "1 God in 3 Persons" is the perfect summary. In our Coptic prayers, we call this the "Consubstantial Trinity", meaning Three who are of the exact same Being.
