But Christ did not say, "This is my male body".

To understand Inter Insigniores, you need to understand that the author was bringing in every argument against the ordination of women without reallyy considering them or their honesty. For example of his dishonesty, he admits that the argument that women are inferior to men is not acceptable (indeed, he tries to pretend that it was never taken seriously), and then he drags it back in, without really admitting he is doing so.

In particular, you have to understand the deeply ingrained sexism of the hierarchy.
