They present themselves in human form in [descriptions] given in the Word.
In human FORM, but not human.
Phil, this may contradict your SDA talking points, but read the Word and discover what the angels DID.
They ate food
They talked
They walked
They stood
They unlocked prison doors
They extended hands
They were in all sense clearly human in form and function
So much so that when we meet them and show them kindness, we will be unaware that they’re angels and not human.
How exactly did they do these very human things Phil?
You’re making conclusions based upon you’re biased premise, where the Word is very clear.
