It should be obvious from the Old and New Testament scripture groupings above that the titles and terms for God such as Savior, Lord, and God are interchangeable in regards to Jesus and Jehovah. The next few scriptures should also eliminate all doubt:
John 20: 27-29 ~ Then saith he to Thomas, ... reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God. Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.
John 14: 8-11 ~ Philip saith unto him, Lord, shew us the Father ... Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, shew us the Father?
John 14: 11 ~ Believe me that I am in the Father, and the Father in me (This is true because they possess the same essence. This is not a silly new age metaphor; it is literally true)
While many Titles of God are interchangeable with regards to Jesus, the proper names of Jehovah and Jesus are not. This is because while Jesus & Jehovah (and the Holy Spirit) share the same essence, they have slightly different personalities. But, they constitute just one God. However, this is not a discussion about the Trinity per se, it is about Idolatry.
Because the Mormons and the Jehovah's Witnesses reject Jesus' claim to be the Alpha and the Omega (as well as the Almighty) in his revelation to John in Rev. 1: 8 ; Rev. 1: 11 ; Rev. 21: 6 ; Rev. 22: 13 , they apparently reason that God doesn't mind sharing his office as Savior with someone else, since he does this with Jesus. The Popes simply declare their own infallibility, and Mary as "Mediatrix" and then go on to promote themselves as necessary for Salvation. Consider:
"the [Watchtower] witness yet includes the invitation to come to Jehovah's organization for salvation." WT 11/15/81 pg. 21
"If it had not been for Joseph Smith and the restoration, there would be no salvation. There is no salvation outside The Church of Jesus Christ of Latter-day Saints" (Mormon Doctrine, p.670).
"There is one universal Church of the faithful, outside of which no one at all can be saved." - Pope Innocent III, Fourth Lateran Council
In reality, it would not matter one iota if the JW's or the Mormons really were the only sources of truth in the world and if the Pope really was infallible. The fact remains that the claim that Salvation is unique to them, (along with Jesus of course) constitutes blatant IDOLATRY according to numerous scriptures. God ALONE is responsible for our Salvation. The idea of Salvation being exclusive to a particular assembly should be just as repulsive to the believer as it would be to bow down to one of the demon gods of the heathen. (Romans 6: 16a)
The hard, cold fact of the matter is that multitudes of people worship their churches rather than God, or a least along side of God. When religious leaders cross the line and make their own church a sharer in Salvation, they make an idol out of their organization and become an ABOMINATION. God will tolerate no rivalry to Himself as Savior, with anyone or anything. It is wise to comply with his wishes.
Speaking to Jews, who in their own minds seemed justified by their organization of rules (instead of blood), God rebukes:
"And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God." - Luke 16: 15
Speaking to Christians, God warns similarly:
Wherefore let him that thinketh he standeth take heed lest he fall. There hath no temptation taken you but such as is common to man...flee from idolatry. 1 Cor. 10:12-14
The "common" tendency of man is to ritually esteem something or someone instead of, or along side of God (like their own church). This is idolatry and is very easy to do, but it must be resisted. God will not tolerate it.... no way, no way, no way.
