The Mason Apron: A Symbol of Innocence, and a Badge of Sacrifice

I did a small dig on the Masonic Apron. Though the sources I read mentioned various significances for the use of the Masonic apron (purity, honor, antiquity), most sources cite the apron, once made of lamb skin, is symbolic of innocence and a badge of sacrifice.

“…made of Lambskin, it is in its fabric a badge of sacrifice. The Lamb in all ages has been not only an emblem of innocence, but also a symbol of sacrifice, and he who wears this Apron with understanding must be prepared for the time when hard things are to be done when trials are to be endured, and fortitude glorified.”

Looking at the apron, of course we recognize this is the Gmail logo:

Then I am reminded of the envelope from North Korea POTUS (awkwardly) held up for the cameras, waist high, in the same position as if it were an apron. Back when this photo was first published , many thought it was representing the large envelope in “Alice in Wonderland.” Or was POTUS really trolling the Freemasons?

Also notice the way he’s holding the envelope. Both hands are signing the letter “Q” in ASL.

Lastly, I came across this passage describing the symbolism of the “envelope” shape of the Masonic apron:

“It has been regarded by many as a great religious symbol. In our present conception there are three parts of man, body, soul/mind and spirit; what the body is to the soul, the soul is to the spirit, namely, a house or habitation, but in oriental thought there were seven parts of man, four earthly and three heavenly, four physical and three spiritual. The four sides of the square symbolized the four physical and the three sides of the flap, or triangle, symbolized the three spiritual parts of man. The apes of the triangle or point of the flap stood for the seventh part of man which was called Atma and which means the eternal spark, the divine flame, the indestructible spirit of the living God in every human being. In this aspect it means that God is not a looker- on at the life of anyone. God is under every man and God is part of every man.”

God is UNDER every man? Under, as in the symbolic location of Hell and Satan?

So it begs the question, are these Masonic aprons actually badges of Satanic ritualistic child sacrifice?
