Is “saviour” (yasha in Hebrew [Strong‘s # 3467], soter in NT Greek [Strong‘s # 4990]) really an exclusive title for God, or can it properly be applied to other individuals?Who is able to forgive sins but God ?
If Jehovah is insisting that no one but himself is ever to be called “saviour,” then He and His inspired Bible writers would never call anyone else by that exclusive title.
So, when we read that Othniel (Judges 3:9) and Ehud (Judges 3:15) are both called “saviour” (same Hebrew word translated “saviour” at Is. 43:11 is translated “deliverer” in KJV - compare ASV), should we really believe they are both Jehovah because “besides [Jehovah] there is no saviour”? If so, we have a new “trinity”: The Father, Ehud, and Othniel!!
“Mystery” religionists and “plural-oneness God” devotees should be interested in Obadiah 21 also. There they can “prove” that all those saviours are Jehovah. Furthermore, they might “prove” that those saviours are Christians who, therefore, will all be Jehovah! For example, if Jehovah alone is saviour, and Jesus is saviour because he saves (Greek: sosei - Matt. 1:21 and soso - John 12:47) men, then Jesus “must” be God. By this same reasoning, since some followers of Jesus also save (Greek: sosei - James 5:20; 1 Tim. 4:16 and soso - 1 Cor. 9:22) men, then they (the saviours of Obadiah 21?) too, must be God!
We realize that Jehovah, as the only Almighty and Most High God, is the ultimate Saviour and the only origin of salvation, and, in that sense, and by comparison, there are no others.
However, it is obvious that other individuals can be, and are, saviours in a subordinate sense, if Jehovah so wills it. That means, then, that Jehovah is the only ultimate saviour (or the only ultimate source of salvation), and, in the cases of Ehud and Othniel, for example, Jehovah was saviour through them.
Yes Jesus is our savior and king, but he is our only savior in the sense of being the only one (excluding God in heaven the source of that salvation who sent him for this purpose) who gave us the opportunity for eternal salvation. This is explained in John 3:17: “Indeed, God did not send the Son into the world to condemn the world, but in order that the world might be saved through him.” - NRSV. God is the source of salvation, Jesus was the instrument.
