Trinity
The Christian doctrine of the Trinity defines God as three divine persons : the Father, the Son , and the Holy Spirit. The three persons are distinct yet coexist in unity, and are co-equal, co-eternal and consubstantial . Put another way, the three persons of the Trinity are of one being...

 Church. This conjunction appears in two New Testament texts: 2 Corinthians 13:14 and Matthew 28:19. The context of 2 Corinthians 13:14, which is the closing of a letter, suggests the church's conjunction of the Father, Son and Holy Spirit may have originated as a doxological formula, while the context of Matthew 28:19 shows that the verbal conjunction of the Father, Son, and Holy Spirit was used early on as a baptismal formula. The oldest extant work in which the exact word "Trinity" (Greek Trias, triados) is used to refer to Father, Son and Holy Spirit, is Theophilus of Antioch's 2nd-century To Autolycus. The relationship between the Father, Son and Holy Spirit was not explicitly expressed in the writings of ante-Nicene Church Fathers exactly as it would later be defined during the First Council of Nicaea (325) and the First Council of Constantinople (381), namely as one substance (ousios) and three persons (hypostaseis). But their Trinitarian concepts did become defined with greater detail over time in this period.

 and Hippolytus of Rome wrote Against Praxeas and Against Noetus, respectively, which may be considered the first extant expository treatments of Trinitarian theology. Both authors use the word Trinity (Latin: Trinitas; Greek: Trias). They wrote these works to combat Patripassianism
Patripassianism

Tertullian's treatise against a Patripassian heretic named Praxeas, who claimed that the Father had suffered with the Son on the cross, is arguably the oldest extant treatise with a detailed explicit Trinitarian theology. In his Against Praxeas Tertullian wrote:
.(Against Praxeas 2).

ca. 220: Hippolytus of Rome

In the early 3rd century, Hippolytus of Rome wrote a treatise Against Noetus, in response to a Christian from Smyrna named Noetus who had been promoting Patripassian views, which Hippolytus deemed heretical. Noetus and other Patripassians, such as Praxeas (see above), claimed that the Father as well as the Son had suffered on the cross. Like Tertullian, Hippolytus explicitly used the word Trinity in his treatise against Patripassian views.

ca. 225: Origen
Origen
Origen , or Origen Adamantius, 184/5–253/4, was an early Christian Alexandrian scholar and theologian, and one of the most distinguished writers of the early Church. As early as the fourth century, his orthodoxy was suspect, in part because he believed in the pre-existence of souls...

Origen's On First Principles (De Principiis or Peri Archon) is the oldest extant Christian theological treatise. Origen develops Trinitarian theology is developed in this treatise, which reveals that by this time the use of the word Trinity to refer to Father, Son and Holy Spirit is standard in orthodox churches.

ca. 256: Novatian

's views on the relations between the Son and the Father, as well as some who attempted to refute Sabellius's views. Athanasius quotes parts of Dionysius' letter in On the decrees of the Council of Nicaea .
