Does Jesus have a gender tho? As stated above, Jesus has a fully human body and nature (or else you are deemed a heretic by the council of Chalcedon). He is described as a man and several churches and rulers have historically claimed to hold a piece of his foreskin, so he must've had a penis.
Therefore:
Either Jesus was agender despite having a penis, therefore penis doesn't imply male gender or
Jesus was male. So either:
Jesus and God don't have the same gender, so they aren't the same entity, which the councils of Nicea and Chalcedon would deem a heresy, or
God can manifest as male or agender, making Them genderfluid.
It's also been mentioned in other parts of this thread, but the holy foreskin has been considered an important relic, and there are accounts of many kings like Charlemagne having owned it.
I know people like to call the holy trinity absurd because of the multiple entities being 1 entity, but I would like to direct your attention to plural people. Holy-trinity-like situations actually occur in real people. Even with different genders.
