Angels and religion

 Yoma (19b) There was a Sadducee who had arranged the incense without, and then brought it inside. As he left he was exceedingly glad. On his coming out his father met him and said to him: My son, although we are Sadducees, we are afraid of the Pharisees. He replied: All my life was I aggrieved because of this scriptural verse: For I appear in the cloud upon the ark-cover. I would say: When shall the opportunity come to my hand so that I might fulfil it. Now that such opportunity has come to my hand, should I not have fulfilled it? It is reported that it took only a few days until he died and was thrown on the dungheap and worms came forth from his nose. Some say: He was smitten as he came out of the Holy of Holies. For R. Hiyya taught: Some sort of a noise was heard in the Temple Court, for an angel had come and struck him down on his face to the ground and his brethren the priests came in and they found the trace as of a calf's foot on his shoulder, as it is written: And their feet were straight feet, and the sole of their feet was like the sole of a calf's foot.
