See this article on Angels in Judaism. I extract an important part:
Assuming Human Form
There is some debate among the great Jewish philosophers whether the
angels that the Torah describes as appearing actually assumed a
visible physical form,(this is the opinion of Nachmanides, Genesis
18:1. ) or they appeared in the course of a spiritual vision or
prophecy—in which the angels appeared as physical beings,(the opinion
espoused by Maimonides, Guide for the Perplexed 2:42. ) According to
all approaches, however, seeing an angel requires extra-sensory
perception, as the bodies of the angels are not comprised of all the
basic elements of a physical being.
and see here - extract:
Real angels don't have bodies, wings, or one drop of physicality.
So the answer is nuanced: angels appear as physical brings without physicality.
– Avrohom Yitzchok May 02 '17 at 08:27We have to ask to what extent his commentary is appropriate for our site which is for those who base their lives on Jewish law and tradition and anyone interested in learning more.
The essential quote from the commentary ends with the sentence “These were three heavenly beings in human bodies.”
Can you please edit the quote to remove everything after that sentence?
