jhine: "...so do you agree with the WT teaching that Jesus is really a created angel?"
Although Trinitarians often mock the idea of Jesus being ‘a created angel,’ it should be noted that the concept of "angel" as "God's messenger" is there.
"Angel" has been defined as "a supernatural being who acts as messenger Mt 1:20" (Shorter Lexicon of the Greek New Testament):
Abbott-Smith: "a messenger, one sent: Mt 11.10, Ja 2.25"
Malachi 3.1 speaks of "the messenger of the covenant" (Heb.: ūmal'akh habberîth) coming to God's people.
Jesus was the One ‘sent by God’ to his people with the message of salvation. (John 3.16)
Keil & Delitzsch explain:
“The
words ‘Behold he (the covenant angel) cometh’ serve to
confirm the assurance, and are still further strengthened by אמר
יי צ (saith
Jehovah of hosts). This promise was fulfilled in the coming of
Christ, in whom the angel of the covenant, the Logos, became
flesh, and in the sending of John the Baptist, who prepared the way
for Him."
Incidentally, the word "apostle" carries a similar meaning: "delegate, envoy, messenger...Hb 3:1 [Applied to Christ: "Consider the apostle--Jesus"]." (Ibid, Shorter Lexicon)
Watchtower's position: “But even here, it might be added, that, were it not for the prevalence of the trinitarian teaching that Jesus was not created, it would not have been necessary to add the word ‘other.’ ” (The Watchtower, 4/15/1970, p. 255)
BeDuhn adds: “‘Other’ is implied in ‘all’ and the NW simply makes what is implicit explicit. You can argue whether it is necessary or not to do this. But I think the objections that have been raised to it show that it is, in fact, necessary, because those who object want to negate the meaning of the phrase ‘firstborn of creation.’ If adding ‘other’ prevents this misreading of the Biblical text, then it is useful to have it there.”
If we take the meaning of the expressions (the firstborn of the creation of God; the beginning of the creation of God) as a reference to Christ as being created (an admitted grammatical possibility by Trinitarians), then the idea does not seem so far-fetched.
