In the New Testament account, the person who betrayed Jesus was a man. His lack of faith and ensuing punishment stands as a symbol of the subordinate position that all men should take. It is expected that even ordained men would be unable to withstand the natural male tendency to buckle under pressure. Jesus didn't ordain men. He didn't ordain any women either, but two wrongs don't make a right.
Men are simply too emotional to be ordained.
Their conduct at football matches, in the army, at political conventions and especially at Promise Keepers Rallies amply demonstrates this tendency. Many men are simply too handsome to lead public worship. To be an ordained pastor is to nurture and strengthen a whole congregation. But these are not traditional male roles. Throughout the history of Christianity, women have been considered to be not only more skilled than men at nurturing, but also more fervently attracted to it.
