who is the son in the holy trinity
God the Son God the Son (Greek: Θεός ὁ υἱός) is the second person of the Trinity in Christian theology. The doctrine of the Trinity identifies Jesus as the embodiment of God the Son, united in essence (consubstantial) but distinct in person with regard to God the Father and God the Holy Spirit (the first and third persons of the Trinity).
Trinity Tertullian, a Latin theologian who wrote in the early 3rd century, is credited as being the first to use the Latin words "Trinity",[32] "person" and "substance"[33] to explain that the Father, Son, and Holy Spirit are "tres personae, una substantia".[34] While "personae" is often translated as "persons," the Latin word personae is better understood as referring to roles as opposed to individual centers of consciousness.
