Then I fell at his feet to worship him, but he said to me, "Don't do that! I am a fellow slave with you and your brothers who have the testimony about Jesus. Worship God, because the testimony about Jesus is the spirit of prophecy." (Revelation 19:10)
Angels know their place. They are fellow creations, called to worship God (Psalm 148:2). As we see in this passage from Revelation, they will not accept our worship. So we need to be cautious. Basically, if you offer your worship to an angel, they will rebuke you. Or, if they don’t, they are not really an angel, but a fallen angel. So much the worse.
Here is an excerpt of this from In The Image of Man:
“Welcome, Chris, my friend.”
Chris fell to the ground in worship.
“No. No, my friend, you must not do that. I am just a messenger.”
Chris felt a presence approach.
“My name is Eran. I have been with you for six and a half years—since you began your walk with Jesus the Christ.”
