Trinitarianism
Trinitarianism
a) Referring to a Roman Catholic order founded in 1198 to redeem Christian captives from Mohammedans.
b) The usual meaning of the term the doctrine of the Trinitarians who hold that the nature of God is one in substance and three in embodiment (Latinpersona). Upon the basis of Platonic realism (q.v.) which makes the universal fundamental and the particulars real in terms of the universal, the Christian Trinitarians made philosophically clear their doctrine of one Godhead and three embodiments, Father, Son and Holy Spiritthree and yet one. The doctrine was formulated to make religiously valid the belief in the complete Deity of Jesus and of the Holy Spirit (referred to in the New and the Old Testaments) and to avoid the pitfalls of polytheism. Jesus had become the object of Christian worship and the revealer of God and thus it was felt necessary to establish (together with the H.S.) his real Deity along with monotheistic belief. A long controversy over the relationship of the three led to the formulation by the Council of Nicea in 325, and after further disputes, by the Council of Constantinople in 381 of the orthodox Trinitarian creed (the Niceno-Constantinopolitan). Roman and Greek Catholicism split on the doctrine of the status of the H.S. The Western church added the expression “filioque” (the H.S. proceeding “and from the Son”) making more explicit the complete equality of the three; the Eastern church maintained the original text which speaks of the H.S. as “proceeding from thet Father.” Orthodox Protestantism maintains the Trinitarian conception. — V.F.
