God calls both men and women to priesthood and always has.  Men chose to be biased and sexist around the 3rd century and exclude women from leadership.  Women were presbyters in the early church which were the only priests we had along with male presbyters.  Which makes the bias, only, against women the thing that is man-made.  The sacrament was never meant be sexist or biased against a person's flesh.  As Jesus said treat all the same and with love - that includes women.  Also Jesus told us the flesh is nothing but the spirit of the person (which has no gender or race, etc.) is everything.  Jesus told us God shows no partiality so we should not judge each other's value for ministry based on their flesh.
