Eduardo.....The problem tho is that the Society has not been consistent in this interpretation. Thus they have on occasion cited 1 Timothy 2:5 to refer to Christ's exclusive mediatorship in prayer (as an intercessor) for all Christians:
***g78 7/8 pp. 6-7 A Man Who Found It ***
Catholics believe that image worship can cause the "saints" to act as mediators between God and the worshiper. However, the Bible indicates that this is wrong, for we read: "There is one God, and one mediator between God and men, a man, Christ Jesus." (1 Tim. 2:5) Besides Jesus Christ, none can mediate with God on our behalf. (Compare John 14:6; Acts 4:12.)
*** w02 7/1 p. 8 Worship God "in Spirit" ***
Is it proper to pray to Jesus’ earthly mother, Mary, or to particular "saints," asking them to intercede with God in one’s behalf? The Bible’s direct answer is: "There is only one mediator between God and mankind, himself a man, Christ Jesus."—1 Timothy 2:5.
See also 15 August 1958 Watchtower, p. 503, 15 May 1969 Watchtower, p. 314, 1 July 1974 Watchtower, p. 396, 15 February 1975 Watchtower, p. 112, 1 December 1988 Watchtower, p. 5, 15 February 1997 Watchtower, p. 28, and 15 February 2000 Watchtower, p. 27. So if the Society is discussing Catholicism, they interpret the scripture one way (i.e. as referring to everyone who approaches God through Jesus), but if they are talking about themselves, they interpret it an entirely different way (i.e. as referring only to the 144,000 in the New Covenant). In another article that had nothing to do with Catholicism, the Society also referred to Christ's mediatorship in general terms without the "technical" legal sense in their use of the term elsewhere:
*** w57 4/15 pp. 237-238 When All Men Again Worship One God ***
When Jesus Christ was on earth did he imitate the mighty hunter Nimrod and try to lead men to worship him? No, he did not. ...He sought first a share in the kingdom of God and told his followers to do the same thing, saying: "You must pray, then, this way: ‘Our Father in the heavens, let your name be sanctified. Let your kingdom come. Let your will come to pass, as in heaven, also upon earth.’ ....Then to show there is only one right form of worship and only one way to the one true God, Jesus said to his followers: "I am the way, and the truth, and the life; no one comes to the Father, but by me." (John 14:6, RS) The reason why Jesus said this was that he had come here to be the go-between or mediator between Jehovah God and men. Under divine inspiration the apostle Paul declares: "There is one God, and one mediator between God and men, a man Christ Jesus, who gave himself a corresponding ransom for all." (1 Tim. 2:5, 6, NW) Being a perfect man on earth and dying sinless as a martyr for God’s kingdom, Christ Jesus offered to God the one acceptable ransom sacrifice for the sins of mankind. So he alone can serve as mediator.
And finally, consider this passage which explicitly refers to Jesus as the mediator for mankind and who acts as mediator with respect to prayer:
"The Bible clearly says that Jesus Christ is mankind's redeemer, so he is mankind's mediator. Therefore, our prayers should be addressed to God through, or in the name of Jesus. (1 Tim. 2:5, 6) This being the case, there is absolutely no Biblical reason why men should canonize saints or pray to them." (Awake!, 8 July 1969, p. 24)
So it is a small wonder why many ordinary Witnesses are confused about the matter.
