Interestingly, there are many 'episcopal functions other than the 'sacramental'. 

'lay' people are increasingly delegated by the Bishop as parish administrators, communion ministers, teachers in the RCIA program, marriage preparation, and more and more other things.

At present, we consider the sacrament of 'ordination' to be required for somme sacraments (not all) and particularly for presiding at the Eucharistic Liturgy and consecrating the Eucharist.

And we restrict 'ordination' only to 'clerics' – those who are male, and who commit to a full-time, life-long, celibate life style.

That is the requirement that  seems to be coming into question. Could 'ordination' and the 'job' of priest be given to a 'non-cleric', a 'lay' person? One who is not necessarily a life-long, full-time 'professional' ??
