STATEMENT OF FAITH
1) GOD: There is one God, Father, Son and Holy Spirit, all coequal within the Godhead.
2) THE INCARNATION & NATURE OF CHRIST: Jesus was fully man and fully God. Yet without sin. To believe this is fundamental to the Faith.
It is my doctrine a person does not need to make a commitment in belief far beyond this teaching.
Few Protestants and Evangelicals consider it necessary to attempt to delve into an analysis of the undivulged aspects of the nature of God and of Christ in the incarnation, and you seldom hear them mention words like: Monophysitism, Dyophysitism, Miaphysitism, Monothelitism, Dyothelitism, Dyoenergism, or the subjects of "ousia and energia". This I believe is because 1 Timothy 3:16 tells us "Great is the mystery of Godliness" and King David in humility expressed "LORD, my heart is not haughty, nor mine eyes lofty: neither do I exercise myself in great matters, or in things too high for me." Psalm 131:1. As long as you believe Jesus was fully man and fully God, I believe it is not at all fundamental to salvation in Christ to express views about the nature, will or "substance" of God.
The Faith has enough division within it already without over complicating the basic beliefs of the Faith as if one is empowered to spiritually dissect God. The proof my teaching on this is correct is in the question - "How many of you would believe the (silly) idea that until you believe one or other of the above mentioned complex theology doctrines, you cannot be saved or born again?" Yet the Orthodox Faith will often force a person to confess these complex doctrines before baptism is allowed.
3) THE GOSPEL BY WHICH WE ARE SAVED:
The true "Gospel by which we are Saved" (1 Cor 15: 1-4 & Luke 24: 44-48) or "Jesus Saves Gospel" is to believe in Jesus Christ crucified, buried and resurrected for our salvation. Jesus was the first person to preach the good news of salvation through him alone, but he did mention repentance. Everyone who truly believes in Jesus repents of their sins, but repentance does not save you, it is simply a quality indicator of real belief.
By being involved in the power of the resurrection of Christ, the Father and Holy Spirit also partake in the gospel, and though true this is not mentioned in the simplicity of the good news that saves.
