Why women can’t be priests?

First of all I want to notice, I am an Orthodox Christian. I believe in God and go to church. But there are several things which I cannot understand. Why women can be a head of monastery but they cannot become priests? And why Christianity is against feminism?

Couple weeks ago I’ve read about the head of Orthodox Church said that feminism is a dangerous phenomenon. He said, in particular, that a woman should not forget about her nature and be mother and woman first of all. He added that he has nothing against of women work and make successful carrier. But don’t become a feminist! Because is dangerous, it appeals to free love and other awful things. Then? “Kinder, Küche, Kirche” (“child, kitchen, church”)?

To understand why feminism is so dangerous I went to the main source of knowledge - Wikipedia. It says, “Feminism is a collection of movements and ideologies aimed at defining, establishing, and defending equal political, economic, and social rights for women. This includes seeking to establish equal opportunities for women in education and employment.” Education, employment… No one word about free love and desecration of values.

I am a woman and I believe in God. I know that first of all any woman thinks about protection and healthy environment for her family and all around. She will always be a woman, she was born with maternal instinct and sense of beauty.
What I want to say, there is nothing to be afraid. A woman will always be the most feminine on this earth, and women can bring only peace and wisdom.

In Caucasian countries there is a tradition, when a woman throws a shawl on the ground, men must stop fighting.

I believe in women, I believe in peace, I believe in life!
