Trinity
Since the beginning of the third century[4] the doctrine of the Trinity has been stated as "the one God exists in three Persons and one substance,
Tertullian, a Latin theologian who wrote in the early third century, is credited with using the words “Trinity”,[12] “person” and “substance”[13] to explain that the Father, Son and Holy Spirit are “one in essence – not one in Person”.[14]
About a century later, in 325, the First Council of Nicaea established the doctrine of the Trinity as orthodoxy and adopted the Nicene Creed that described Christ as “God of God, Light of Light, very God of very God, begotten, not made, being of one substance (homoousios) with the Father”.
Paul the Apostle"s blessing: “The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all” (2 Corinthians 13:14), while at the same time not contradicting the Jewish Shema Yisrael: “Hear, O Israel: The Lord our God is one Lord” (Deuteronomy 6:4).[1][16]
