The purpose of New Testament is to identify the Lord Jesus as the Son of God (because that’s His primary administration for salvation). Though the Three are equal in Deity, power and essence, They are in an order of authority (Father, Son, Spirit - Jhn 10:29; 14:28; 1Co 11:3; 15:24); as the One sending has more authority than the One sent (e.g. the Son sent the Spirit from the Father - Jhn 14:16, 26; 15:26; Heb 1:2).

The Son and the Spirit (Act 5:4) both represent God, but esp. the Son, manifesting "the fullness of the Godhead;" and the Father is the Godhead particularly, but all Three “equal” (Phl 2:6) generally (Act 17:29; Rom 1:20; Col 2:9). The "fullness," meaning the Son is the complete manifestation of the Father--or God, in all aspects, except authority; God is also "the Father of all spirits" (Heb 12:9).

Thus it is "Son of God" or "Son of the Father" (2Jo 1:3); Spirit of God or "Spirit of the Father" (Mat 10:20; Jhn 15:26; Rom 8:15). We see “Son of God” and “Spirit of God,” but not the Father of God—because God is the Father. The Lord Jesus is sometimes called God or even the Father (Isa 9:6), but it's in the sense of representing God or the Father, in order to show that the Son conveys all that God determines with His mind concerning the believer. The One sending has more authority than the One sent (e.g. the Son sent the Spirit from the Father - Jhn 14:16, 26; 15:26; Heb 1:2).

This also answers to the beginning of most of Paul's epistles: "Grace to you and peace from God our Father, and the Lord Jesus Christ" (Rom 1:7; 1Co 1:3; 2Co 1:3, etc.); the following passages also coincides with this doctrine (Jhn 20:17; Rom 15:6; 1Co 8:6; Eph 4:6).

The point is that the Father wants believers to see the Lord Jesus as the Son more than any other title, because carries the most significant relation to us as the One who only can save and bring us to the Father. Christians will be the greatest entity following the Trinity, because of being the only ones created in God’s image!

I realize this information may seem quite different to most, because I have yet to see any teaching on the Trinity in this way. It's just what I've come to believe during my 43 year walk in Christ. Of course, how one understands and believes the Trinity is not essential doctrine (essential doctrine is that which teaches how to be saved), so don’t think that however you conceive the Trinity can affect your salvation!

God’s blessing to your Families, and God be blessed!

The Christian life is not our living a life like Christ, or our trying to be Christ-like, nor is it Christ giving us the power to live a life like His; but it is Christ Himself living His own life through us; 'no longer I, but Christ.’” -MJS
