context_page_description: The Christian doctrine of the Trinity holds that God is one God, but three coeternal consubstantial persons or hypostases—the Father, the Son, and the Holy Spirit—as "one God in three Divine persons". The three persons are distinct, yet are one "substance, essence or nature". In this context, a "nature" is what one is, whereas a "person" is who one is. The subset of Christianity that accepts this doctrine is collectively known as Trinitarianism, while the subset that does not is referred to as nontrinitarian. Trinitarianism contrasts with positions such as Binitarianism and Monarchianism, of which Modalistic Monarchianism and Unitarianism are subsets.
  While the developed doctrine of the Trinity is not explicit in the books that constitute the New Testament, the New Testament possesses a "triadic" understanding of God and contains a number of Trinitarian formulas. The doctrine of the Trinity was first formulated among the fathers of the Church as early Christians attempted to rationalize the relationship between Jesus and God in their scriptural documents and prior traditions.
context_section_description: Perichoresis (from Greek, "going around", "envelopment") is a term used by some scholars to describe the relationship among the members of the Trinity. The Latin equivalent for this term is circumincessio. This concept refers for its basis to John 14–17, where Jesus is instructing the disciples concerning the meaning of his departure. His going to the Father, he says, is for their sake; so that he might come to them when the "other comforter" is given to them. Then, he says, his disciples will dwell in him, as he dwells in the Father, and the Father dwells in him, and the Father will dwell in them. This is so, according to the theory of perichoresis, because the persons of the Trinity "reciprocally contain one another, so that one permanently envelopes and is permanently enveloped by, the other whom he yet envelopes". (Hilary of Poitiers, Concerning the Trinity 3:1).
  Perichoresis effectively excludes the idea that God has parts, but rather is a simple being. It also harmonizes well with the doctrine that the Christian's union with the Son in his humanity brings him into union with one who contains in himself, in the Apostle Paul's words, "all the fullness of deity" and not a part. (See also: Divinization (Christian)). Perichoresis provides an intuitive figure of what this might mean. The Son, the eternal Word, is from all eternity the dwelling place of God; he is the "Father's house", just as the Son dwells in the Father and the Spirit; so that, when the Spirit is "given", then it happens as Jesus said, "I will not leave you as orphans; for I will come to you."
