|To quote something that Jesus said to people who were asking him about the afterlife: "In the resurrection, they neither marry nor are given in marriage, but become like angels". I think the implication there is pretty clear: in God's domain, biological qualities like gender are not applicable. Therefore, God is neither male nor female.|
There are so many unsubstantiated assumptions in that first statement that I don't really know where or how to respond.
To translate: in one human, as in non-divine, written account of a conversation that may or may not have occurred (but that was written down at least several years after the event even if it did occur) with a person that may or may not either have existed and/or have been the son of what is either an indefinable infinite or a vengeful superhuman smiter, there is a statement that marriage doesn't occur after death because people become like hypothetical creatures with no recognised definition, observed behaviour or tangible physical form. Based on that, there is an assumption that those ethereal creatures are genderless, rather than the equally plausible ideas that they are either inert or sex-obsessed and commitment phobic. Therefore, God is neither male nor female.
Sorry, you're free to believe whatever, and there are many different strands to thinking, but I get upset by attempts to present intuitive assumption as rational logic, especially by otherwise intelligent commentators.
