If I may? My deacon has given me a very simple answer for this question: None of those that Jesus originally chose to spread his word (the apostles) were women, and therefore, out of tradition, none of the Priests are women.
Also, it has a lot to do with God. If you think about it, God chose the woman to be the nurturer of the family, whereas man was meant to be the protector, the teacher, the provider, and the disciplinarian of the family. It is a woman’s job to help with this, but the man, consequently, is the head of the household. This is also why God is a man. If God were a woman, the world would be in chaos, because he would be a nurturer, but would have no control over his children, because he didn’t have the aspects of a man.
Thus, when Jesus was born, he was not born a woman, but, as a spiritual father and leader, he was born a man: a man meant to lead his flock, discipline them, teach them, provide for them, and protect them. He was also the head of his flock, the head of his “household.”
Therefore, out of tradition, since God is not a woman, and Jesus is not a woman, none of the apostles were women, and no Priest is a woman.
An interesting proof of this can also be found in the creation story in the book of Genesis: God made man first. What do you do when you start a organisation of any kind? You build the foundation of that organisation by choosing who will do what, and what the chain of command will be. And who is the first person you appoint to the first job in this organisation? The leader; the person in charge. Therefore, God made man first, to lead. And, when God decided it was not good for man to be alone, that he needed assistance, he took Adam’s rib, and appointed Eve as his second-in-command: his wife.
Seeing as the first person to lead on God’s Earth was man, and not woman, naturally, a man would be the father of his family, and being the father, he would represent God and be the leader to those that he loves.
The Priest is a very busy individual. He sees his “flock,” or, rather, his parish, as his family, and he is a Father of that family. Therefore, concerning gender, a woman is not meant to take that place, because a woman cannot be a man.
This is also why Priests are celibate: they spend every waking hour thinking about, helping, and leading his parish family. In a sense, the Priest is the spiritual representative of our main authority, our heavenly Father. This is also why we call the Priest Father.
So, that’s my answer, and I hope that I have helped you. If not, if I were you, I would go to your local deacon or Priest and ask him.
