This will be a work in progress, especially as new quotes come out to support this Watchtower doctrine. Keep in mind that this post is not intended to be an argument for or against this Watchtower teaching. Rather, it’s meant to be a resource to accurately represent Watchtower teachings from their own sources. If you’re interested in my theological views on this matter, please go HERE.
““The Mediator of a New Covenant”
11, 12. How is Jesus’ role as Mediator unique?
11 Read 1 Timothy 2:5, 6. Jesus is the “one mediator between God and men.” He is “the mediator of a new covenant.” (Heb. 9:15; 12:24) However, Moses is also spoken of as a mediator—the mediator of the Law covenant. (Gal. 3:19) How, then, is Jesus’ role as Mediator unique?
12 The original-language word translated “mediator” is a legal term. It refers to Jesus as a legal Mediator (or, in a sense, an attorney) of the new covenant that made possible the birth of a new nation, “the Israel of God.” (Gal. 6:16) This nation is composed of spirit-anointed Christians, who form a heavenly “royal priesthood.” (1 Pet. 2:9; Ex. 19:6) The Law covenant, with Moses as mediator, was not able to produce a nation like that.” (SOURCE)
“Those for Whom Christ Is Mediator. The apostle Paul declares that there is “one mediator between God and men, a man, Christ Jesus, who gave himself a corresponding ransom for all”—for both Jews and Gentiles. (1Ti 2:5, 6) He mediates the new covenant between God and those taken into the new covenant, the congregation of spiritual Israel. (Heb 8:10-13; 12:24; Eph 5:25-27) Christ became Mediator in order that the ones called “might receive the promise of the everlasting inheritance” (Heb 9:15); he assists, not the angels, but “Abraham’s seed.” (Heb 2:16) He assists those who are to be brought into the new covenant to be ‘adopted’ into Jehovah’s household of spiritual sons; these eventually will be in heaven as Christ’s brothers, becoming a part with him of the seed of Abraham. (Ro 8:15-17, 23-25; Ga 3:29) He has transmitted to them the promised holy spirit, with which spirit they are sealed and are given a token of what is to come, their heavenly inheritance. (2Co 5:5;Eph 1:13, 14) The total number of those who are finally and permanently sealed is revealed in Revelation 7:4-8 as 144,000.” (SOURCE)
“Blessings to Mankind in General. While Jesus’ mediatorship operates solely toward those in the new covenant, he is also God’s High Priest and the Seed of Abraham. In fulfilling his duties in these latter two positions, he will bring blessings to others of mankind, for all the nations are to be blessed by means of Abraham’s seed. Those in the new covenant are first blessed by Christ, the primary Seed (Ga 3:16, 29), being brought in as associate members of the seed. Being made kings and priests by reason of the new covenant that he mediated, they will share in administering the blessings of Jesus’ sacrifice and of his Kingdom rule to all the nations of the earth. Christ’s mediatorship, having accomplished its purpose by bringing “the Israel of God” into this position, thus results in benefits and blessings to all mankind.—Ga 6:16; Ge 22:17, 18.”
There are, thus, others not of the 144,000 “sealed” ones who also pray to Jehovah God in the name of Christ, putting faith in the merit of his ransom sacrifice. This sacrifice is not only for those for whom Jesus mediates the new covenant but also for all mankind expressing faith in Christ. (1Jo 2:2) These not in the new covenant also appreciate that “there is not another name under heaven that has been given among men by which we must get saved.” (Ac 4:12) They, too, look to Jesus Christ as their great heavenly High Priest, through whom they can approach God and through whose ministration they can get forgiveness of sin. (Heb 4:14-16) Revelation 21:22-24 points out that ‘the nations will walk in the light of New Jerusalem,’ where Jehovah God is the light and the Lamb Jesus Christ is the lamp.” (SOURCE)
“Moses was the “mediator” of the Law covenant made between God and the nation of Israel. (Gal. 3:19, 20) Christ, though, is the “mediator of a new covenant” between Jehovah and spiritual Israel, the “Israel of God” that will serve as kings and priests in heaven with Jesus. (Heb. 8:6; 9:15; 12:24; Gal. 6:16) At a time when God was selecting those to be taken into that new covenant, the apostle Paul wrote that Christ was the “one mediator between God and men.” (1 Tim. 2:5) Reasonably Paul was here using the word “mediator” in the same way he did the other five times, which occurred before the writing of 1 Timothy 2:5, referring to those then being taken into the new covenant for which Christ is “mediator.” So in this strict Biblical sense Jesus is the “mediator” only for anointed Christians.” (SOURCE)
“the new covenant is not a loose arrangement open to all mankind. It is a carefully arranged legal provision involving God and anointed Christians.” (SOURCE)
“The people of all nations who have the hope of everlasting life on earth benefit even now from Jesus’ services. Though he is not their legal Mediator, for they are not in the new covenant, he is their means of approaching Jehovah. Christ said: “I am the way and the truth and the life. No one comes to the Father except through me.” (John 14:6) All who will gain life on earth must direct their prayers to Jehovah through Jesus. (John 14:13, 23, 24) Jesus also serves as a compassionate High Priest who is able to apply in their behalf the benefits of his sacrifice, allowing them to gain forgiveness and eventual salvation.—Acts 4:12; Hebrews 4:15.
Consequently, 1 Timothy 2:5, 6 is not using “mediator” in the broad sense common in many languages. It is not saying that Jesus is a mediator between God and all mankind. Rather, it refers to Christ as legal Mediator (or, “attorney”) of the new covenant, this being the restricted way in which the Bible uses the term. Jesus is also a corresponding ransom for all in that covenant, both Jews and Gentiles, who will receive immortal life in heaven. The apostle John referred to these at 1 John 2:2. But he indicated that others too will receive the benefit of Christ’s sacrifice: “He is a propitiatory sacrifice for our sins, yet not for ours only but also for the whole world’s.” (SOURCE)
