hi deputy dog
malachi 3:1 is a specific prophecy Jesus mentions as refering to him and john the baptist who prepares the way for him.
He identifies himself as the messenger/angel of the covenant. Angel simply means messenger in hebrew. All we know of angels is they are spirit creatures like God and Jesus and called messengers because they do Gods work for him and in malachi here the prophecy is identifying Jesus as an Angel/messenger of the covenant which he testifies to in mathew 10:11.
So people saying Jesus can't be an angel because they are a different race type argument or he just isn't an angel is just being tricky. When they know this scripture refers to Jesus being the 'Angel of the covenant' confirmed by himself later. And that angels are the same race as God and Jesus which is that they are all spirit creatures.
thats why it can be just a name change.
