The Mysteries of Saint John the Apostle and Holy Virgin 12
1And I said unto the Cherubim, 'My Lord, of what kind was this righteousness wherein Adam was arrayed, and which he received from His hand?' And the Cherubim said unto me, 'On the day wherein God created Adam, Adam was twelve cubits in height, and six cubits in width, and his neck was three cubits long. And he was like unto an alabaster stone wherein there is no blemish whatsoever. But when he had eaten [of the fruit] of the tree, his body diminished in size, and he became small, and the righteousness wherein he was arrayed departed and left him naked, even to the tips of his fingers, that is to say, to his very nails. If he was not cold in the winter, he was not hot in the summer.'
2And I answered and said unto the Cherubim, 'My Lord, at the time when God created Adam, He also created Eve with him from the heavens (?). But, on the other hand, I have heard that God created Adam and Eve from the beginning, and, again, I have heard that God brought a deep sleep upon Adam, and that when he was unconscious, He took one of the ribs from his side, and made it into a woman, and that He filled up the place where the rib was in his side with flesh. The Almighty did not then create two bodies, there being [only] one body.' And the Cherubim answered and said unto me, 'Hearken, and I will explain unto you everything. At the time when God created Adam, He created Eve also with him, in one body, for at the time when the Master was working at Adam, the thought concerning Eve was with Him. For this reason two bodies came from one body, but He did not separate them from each other immediately. At the time when He brought slumber upon Adam, and Adam fell asleep, and slept heavily, He brought Eve forth from him, and she became his wife. She was, of a surety, hidden in the rib of the left side [of Adam] from the day wherein God created him. Consider, then, with great attention the sign which is in the sons of Adam.'
