The Godhead (God) is traditionally said to consist of the Father, the Son, and the Holy Spirit. This is also called the Trinity (the "tri" signifying three parts).
The "d" character next to trinity is actually the Greek letter "del," and it means that it's a partial differential equation. So, we break down each term with respect to the denominator's variable.
Ah, stop there. Soundgarden, what would the partial of the Father look like? Love*Mercy, I would assume. For the Son, Wisdom*Sacrifice, and the Holy Spirit, Counsel*Truth.
