I would be careful with careless accusations of one who is in error. I have stated my reasons for not discussing semantics and one word from the OT. This does not mean I dismiss the OT.
Tell me Brad why don't you want to discuss the NT? Is it because the NT can prove you are the one in error? Lets us the OT to prove that we need to move to the NT to complete this discussion.
Isaiah 43:11-12
1 "I, even I, am the LORD;
And there is no savior besides Me.
12 "It is I who have declared and saved and proclaimed,
And there was no strange god among you;
So you are My witnesses," declares the LORD,
"And I am God.
NAS
Hosea 13:4
4 Yet I have been the LORD your God
Since the land of Egypt;
And you were not to know any god except Me,
For there is no savior besides Me.
NAS
So who is the savior in the NT?
You see Brad the NT is the fulfillment of the Old. Who according to the NT revelation is the Savior?
Ephesians 5:22-24
22 Wives, be subject to your own husbands, as to the Lord. 23 For the husband is the head of the wife, as Christ also is the head of the church, He Himself being the Savior of the body. 24 But as the church is subject to Christ, so also the wives ought to be to their husbands in everything.
NAS
Philippians 3:20-21
20 For our citizenship is in heaven, from which also we eagerly wait for a Savior, the Lord Jesus Christ; 21 who will transform the body of our humble state into conformity with the body of His glory, by the exertion of the power that He has even to subject all things to Himself.
NAS
1 Timothy 4:10
10 For it is for this we labor and strive, because we have fixed our hope on the living God, who is the Savior of all men, especially of believers.
NAS
2 Timothy 1:7-11
8 Therefore do not be ashamed of the testimony of our Lord, or of me His prisoner; but join with me in suffering for the gospel according to the power of God, 9 who has saved us, and called us with a holy calling, not according to our works, but according to His own purpose and grace which was granted us in Christ Jesus from all eternity, 10 but now has been revealed by the appearing of our Savior Christ Jesus, who abolished death, and brought life and immortality to light through the gospel, 11 for which I was appointed a preacher and an apostle and a teacher.
NAS
Titus 1:1-4
1:1 Paul, a bond-servant of God, and an apostle of Jesus Christ, for the faith of those chosen of God and the knowledge of the truth which is according to godliness, 2 in the hope of eternal life, which God, who cannot lie, promised long ages ago, 3 but at the proper time manifested, even His word, in the proclamation with which I was entrusted according to the commandment of God our Savior; 4 to Titus, my true child in a common faith: Grace and peace from God the Father and Christ Jesus our Savior.
NAS
Lets stop here and take a long look at Titus 1:4. I suppose Paul doesn’t understand the meaning of “echad” since Paul lists two persons in this verse, God the Father, and Christ Jesus His Son who is our Savior. Now since Yehova states in both Isaiah and Hosea that He is the Savior who is Jesus Christ? The only logical answer is Jesus Christ is God. So why do the NT authors keep referring to the Father and the Son as different persons? If God is spirit and the Holy Spirit works in use and regenerates us (Titus 3:5) is it your contention that a spirit has a spirit?
If you want to disprove the Trinity you will have to disprove it from the NT. Do you have children? Have you killed the disobedient ones? Do you keep two sets of dishes; eat pork, lobster, and other foods prohibited under the Torah? Unless you keep the OT to the letter you are being illogical to appeal to the OT to disprove a NT teaching.
