Fundamental Christian Doctrines
The Doctrine of the Trinity
"There are in the Godhead, three persons, one in substance, co-eternal, equal in power, the Father, Son and Holy Spirit."
Western Church: "The Holy Spirit proceeds from the Father and the Son."
Eastern Church: "The Holy Spirit proceeds from the Father."
The Doctrine of Incarnation
The divine Word which is God is incarnated in Jesus Christ. He is the Word made flesh. (This is also called the "doctrine of the Logos").
The Nature of Christ
"Jesus Christ is true God and true man. He has two natures, one divine and one human. Both are united in one person, and that Person is divine."
