So, does any know what role deaconess's actually played?
It is my understanding that the functions of the Deaconess were as follows:
Teaching, by word and deed, the females who were new to the faith (whether catechumens or newly baptized). In essence, they were something of a role model for those young in the faith to emulate, go to for help, etc.
Counselling those who were in need, whether they be those who were weak in the faith, those who had to live with pagan spouses, or whatever other needs.
Assist in the baptism of females (people were baptized naked in the early Church).
Do charitable work, such as distribute help to the widows in need, feed those who were starving, etc.
Past this, I think it is mostly speculation, though I admit that my reading on the subject is very limited.
