I would suggest:
The short answer is yes.
The longer answer is a qualified yes, with some caveats.
The short answer is yes because Jehovah’s Witnesses teach that Jesus is Michael the archangel, their leader, eldest and most powerful, and have taught this since the very beginning of the religion. They have sometimes described Jesus an “angel” too.
The reason a longer answer might be interesting and relevant is because it is somewhat surprising (it was surprising to me at least) just how few times Watchtower literature has stated flat out that Jesus is an “angel”, as simple as that. After some searching, I can only find a handful of examples in their entire history where they have called Jesus an angel. But maybe I’ve overlooked some! So firstly, I would be really interested and appreciative if others know of examples where Jesus is called an “angel” in Watchtower literature.
Statements that Jesus is Michael the archangel are easy to find, but in many ways that is not as interesting, because even some Trinitarian churches (SDA) and leaders (Luther and others) can agree/d that Jesus is the archangel Michael. They would argue Michael is one of the names of Jesus, but they don’t think it makes him an angel, or subordinate to God.
I have my own theory as to why JWs so seldom describe Jesus as an “angel”. and why, in contrast, their opponents so often highlight their belief in Jesus as an “angel”. But I’m interested to hear what others think, and especially interested in WT references that called Jesus an “angel”.
