When...

When Salome asked when the things would be known that she asked about, the Lord said, "When you have trampled on the garment of shame and when the two become one and the male with the female is neither male nor female."

Gospel of the Egyptians, quoted by Clement of Alexandria, Strom. 3.13.92

(note: this Greek 1st/2nd CE text is different from the later Coptic text of the same name in the Nag Hammadi Library)

When the two will be one

For the Lord Himself, being asked by a certain person when his
kingdom would come, said, When the two shall be one, and the
outside as the inside, and the male with the female, neither male
or female.

2Clement 12:2 (mid-second century CE)
