Shepherdless,
Yes there are many zany things in Thomas, as there are - in our eyes - in all of the writings from those times. But this is exactly what those Jesus-followers believed and how they thought. Reading their material gives us an insight into the melee of thoughts that were flying around, thicker than flakes in a snow storm.
I suggest that familiarity with the canonised texts (Old Testament and New) has blunted our sensitivities - or we tend to make excuses or rationalizations.
BTW, the Watchtower says that all the resurrected heavenly class of 144,000 are not female. All will be changed. I think that's zany, but that's their reality.
"These all must receive a change of nature at their resurrection, being made partakers together of 'divine nature,' in which state none will be women, for there is no female sex among spirit creatures, sex being God's means for reproduction of earthly creatures." (Insight on the Scriptures, Vol 2, page 1196)
