Paula

I noticed that the word used in Rom. 16:1, diakonon, is also used of Christ in Rom. 15:8. diakonos would be the “lexical” or dictionary form which is always the nom. masculine. We should also note that the feminine (acc. sing. fem.) form diakonian is used of Paul himself in 1 Tim. 1:12.

Mounce’s Analytical Lexicon shows diakonon as both masc. and fem.; that is, the form itself does not indicate grammatical gender.

Which is another important point: grammatical gender has no bearing whatsoever on biological gender. Only English does that.
