That's news to me. Psalm 104:4 says they are fire. They are spiritual beings (asomata, lit. without bodies) who can take any form in their appearance to us. So, their "bodies" are simply appearances.
Gen 19...and they did eat
Genesis 19 is one of those OT passages where one just raises his eyebrows and says 'okay..." and moves on, because the scribe was having mushrooms for dinner that night.
Pretty much like Gnesis 18:1-8 where Abraham feeds God with "butter, and milk, and the calf..."
Think of it this way Kosta. If God went out of His way to tell us, on several occasions, that angels have substance, they eat, etc. He must want us to know that fact.
