In the Roman Empire, as a general rule that was correct. However, I recently heard a presentation on the crucifixion by a Biblical scholar (Orthodox, unlike this ninny), and she stated that in Judea, as a concession to Jewish laws regarding modesty, the victims were clothed in loin cloths. So Jesus did appear on the cross exactly as traditionally depicted. It was Jewish modesty, not later Christian prudery that depicted Christ wearing a loin cloth.
That said, we can be certain that Christ was fully man, in all aspects. The Bible and Christian teaching are clear that Jesus was the only begotten Son of God. Not the only begotten son-daughter, or the only "thing."
This is some sort of gnostic heresy, positing Christ as somehow not fully human. Nothing new under the Sun.
this is from the same illiterati that brough the hbo series about an aleged female pope.
One misconception is that first century jews were never celibate. But that is to confuse the Judaism of that time with the rabbinical Judaism that survived the destruction of the Temple. John the Baptist is another example of a deeply religious Jew who did not marry, as was Paul.
