I'm a woman, not a monastic, and I've been at the altar with the blessing of the priest because they needed some work done back there, and there weren't any men in that parish who knew how to do it. So far, all they'd manage to do was screw everything up. He was with me the entire time. I was asked to help them get their church whipped into shape for their feast day. I had no reason to touch the altar table, just work in the side areas where various items are stored.
I'm pretty sure they didn't burn anything down, and last I saw the Matushka of that parish, she said she always thinks of me when she sees how things are working there.
There's a place for everyone in a parish.
Nuns at the monasteries perform duties at the altar during services. They also know how to change out or fix pumps and plumbing, maintain vehicles, deal with random bears that wander in, run construction work like a general contractor, do construction work in full habit, milk goats, garden, make candles, soap, food, hospitality, teach, and chant prayer that makes your heart break. That's the short list.
St. Eirene of Chyrsovalandou was a Gerondissa and Deaconess and miracle worker. She followed the rule of St. Arsenios and was in the tradition of the Cappadocians, St. Basil the Great, etc. Back then, things were simpler, so she cleaned the toilets.
But women aren't priests or bishops. They can be titled Apostle though, like St. Mary Magdalene, for one, is titled Apostle to the Apostles, and of course the Theotokos is the greatest of all Saints.
