True worship should be directed only towards God. You should never worship one of God’s servants, be it angels, popes, saints, prophets, etc. Any good that angels or prophets do is the result of God’s grace and power. Therefore you need to worship God who gave them the ability to serve him.
This point is made very clearly at the end of the book of Revelation when the Apostle John attempts to venerate the angel who revealed the vision to him:
I, John, am the one who heard and saw these things. And when I had heard and seen them, I fell down to worship at the feet of the angel who had been showing them to me. 9 But he said to me, “Don’t do that! I am a fellow servant with you and with your fellow prophets and with all who keep the words of this scroll. Worship God!” (Revelation 22:8-9 NIV)
The point here is that we should not be overly impressed by other servants of God, no matter how holy they are. After all, they are simply God’s handiwork the same as us. Anything impressive they do should not bring glory to themselves, but to God, since He is the one who created them.
