From Rejoice in the Catholic Faith

The "Trinity" or, "Holy Trinity" of the Father, the Son, and the Holy Spirit

  • also, the "Blessed Trinity"

Terminology of the Trinity

Godhead

The Trinity may also be referred to as the "Godhead"

  • = God in the full nature of the Trinity
    • from Middle English God + hede (nature of)
  • note: the Father is the "source and origin" of the Godhead, but the Godhead indivisibly consists of the Father, the Son and the Holy Spirit

hypostasis

refers to the "Persons" of God; in Latin persona

  • from Greek for "substance"
    • from hypo- (under) + stasis (standing or position)
  • "hypostatic union" refers to the "union of the divine and human natures... of the Son of God, Jesus Christ" (CCC Glossary)

Triune

a similar reference to "Godhead" for the Holy Trinity

  • but also used as an adjective, as in "the Triune God"

Athanasian Creed

or Quicunque vult

  • an important early Church statement and explanation of the Holy Trinity
"Now this is the Catholic faith: We worship one God in the Trinity and the Trinity in unity, without either confusing the persons or dividing the substance; for the person of the Father is one, the Son's is another, the Holy Spirit's another; but the Godhead of the Father, Son and Holy Spirit is one, their glory equal, their majesty coeternal"  (Athanasian Creed: DS 75; ND 16). 

The Trinity

The Holy Trinity is the mystery of God in three Persons: Father, Son, and Holy Spirit

  • the Trinisy consists of the
    • Persons of God: Father Son and Holy Spirit
    • Natures of God: Creator, Redeemer, and Sanctifier
  • the Trinity was source of much conflict and contention in the early Church
  • and, ultimately, a core tenant of Church doctrine
    • Jews were offended that fellow Jews worshiped Christ, as Judaism was supposed to be monotheistic
    • Romans considered Christians atheistic, as they rejected Roman gods and refused to worship Caesar
    • gnostics and other heretics believed that Jesus fully God and not a Man, thus he was either not a man or not God
  • St. Thomas Aquinas deeper thought on the Trinity in Summa Theologica
    • involves extensions from the concepts of the Trinity and the Oneness of God:
    • One God
    • Two Processions
      1. The Father > The Son (Generation)
      2. The Father and The Son > Holy Spirit (Spiration)
      • Three Persons
        1. The Father
        2. The Son
        3. The Holy Spirit
      • Four Relations
        1. The Father > The Son = Paternity
        2. The Son < The Father = Filiation
        3. The Father and The Son > The Holy Spirit = Active Spiration (originiation)
        4. The Father and The Son < The Holy Spirit = Passive Spiration (procession)
      • Five Notions
        1. The Father > innascibility or unbegottennes
        2. The Father > paternity, i.e. The Father > The Son
        3. The Father and The Son "spirate" the Holy Spirit
        4. The Son = both Filiation and Spiration
        5. The Holy Spirit = Procession
