OK folks,
Gen.18;1-8 The LORD appeared to him by the oak tree.
Gen.18:5 He fetch a morsel of bread for his guest.
Gen.18;6 Sarah makes meal, knead it and made cakes.
Gen.18:7 Abraham ran to the herd and took a calf, tender
and good.
Gen.18:8 He set it before them and he stood by them under
the tree while they ate the food.
So you are telling me, God or his Angels ate solid food.
