In this next installment of my exploration of the Bible and transgender persons, I review Isaiah 56:4-5 and Deuteronomy 23:1, both of which concern the acceptance of eunuchs. These texts are sometimes used to decry the use of GRS/SRS to treat gender dysphoria, but in reality there is a much more complex relationship at play. While it is true that Deuteronomy 23:1 appears to prohibit many forms of body modification, it does not differentiate between involuntary versus voluntary modification – something which some believe to be an incomplete and even haphazard ruling. But Isaiah 56:4-5 appears to over-rule Deuteronomy 23:1, in one of the very rare cases where God actually over-rules a previous religious law established by himself.
I recommend reading the shorter Deuteronomy 23:1 first, then Isaiah 56:4-5 so you can see the texts in the correct order.
