We had another thread where these issues were talked about endlessly. Some of the topics covered were:
1. The roles of the Theotokos and the Forerunner in comparison to this subject
2. The roles of women in the Church and in the household according to the Scriptures
3. The roles of deaconesses in the ancient Church and the cultural context
4. The cultural context of the roles of pagan priests as compared to the Christian presbyters
5. The role of the Liturgy and the differences between the Liturgy celebrating the holy sacraments vs. the secular living outside a Liturgical setting
6. The "Icon of Christ" question, and the debate on whether it should be confined to gender, or to extend to race if possible (shouldn't a priest be from the tribe of Judah for instance?)
These are all I can think of off the top of my head. Quite a lengthy discussion and certainly a very important way of approaching this issue is to study these points I laid out above.
One of the other things that a friend suggested a loooong time ago to me as we were conversing on this issue was studying the ecclesiological theology of St. Ignatius, which convinced him why women cannot be ordained to the priesthood. I've personally taken a more nuanced stand like HE Metropolitan Kalllistos. That is not to say I support female priesthood. But as I understand some of the historical restrictions to the priesthood in the ancient world, not merely just gender, but also marriage history, history of reasons for possible castration, history of being involved in wars or killing, etc. In addition, many of the things we do in liturgy, the choice of the elements for the Eucharist, the choice of chrism, the proper form of praying, perhaps even proper form of writing icons, all of which can be put in the "restrictions" category of which none has been theologically explained fully or defended. Therefore, the restriction of priesthood along with other sacramental venues need to be discussed further as well. Why just female priesthood when we can also discuss a veteran? Why weren't veterans allowed to be priests? Why aren't those who voluntarily castrated themselves but repented later on can't be priests. Why should we restrict ourselves to just wine to be the blood of Christ?
Also, another issue. Why did the married episcopacy die down? And for married priests, what does it mean that a married man, who both him and his wife make up "one body, soul, and spirit", become a priest in the context of his undying unity with his wife?
And I suppose the role of laity and clergy, and how both work together is also another point to address in this matter.
I guess, at this moment of the Church's stage in knowledge, we stand ignorant for the most part on these issues on a full theological level. So until then, I probably would stand on the side of "humble mystery" to keep the "status quo" for the Orthodox Church, and I pray and fast so that the Holy Spirit can guide me, without jumping to conclusions for the sake of "human rights/equality."
