Is that possible? To worship angels? I don't think so. But then again if you allow your mind to believe that everything that happens to you is the direct result of a angel, then it's possible to not only worship them, but create a false religion in your mind. There is only one worthy of all worship and that is Jesus Christ. Now if you find yourself in a church service and someone says "there's a angel here and he wants to heal you, come forward and let us worship", I'd get ghost and leave.
