I used to think that, too, which is why I didn’t leave Catholicism for Protestant ministry. I assure you, that God has and does call women to sacerdotal ministry.
You have already adopted the Protestant heresy of becoming your own Pope and adhereing to Dogmas, Doctrines and Teachings that you yourself define. This is already in direct rupture with the Sacred Deposit of faith that has been handed down to us, and interpretted ultimately by the Successors of St Peter the Apostle. Furthermore, you even claim more power than the Pope, since even he is not able to change what has been handed down, but you have.
It’s indicative of their recognition that there are people not being served and a need to reach out where traditional ministry cannot. I have absolutely no interest ministry to active Catholics. My ministry is to the unchurched and to inactive Catholics. The marginalized, the disenfranchised, the wounded.
To reach out to the marginalised and disenfranchised in society is the call and duty of ALL Christians not just the clergy (and those who claim to be clergy). More importantly however is the call to penance for the kingdom of heaven is close at hand. In terms of catechesis to lapsed Catholics, all that is needed is sound doctrine and dogma and orthodox teaching. Doing other than this would be spreading false teachings and lying to those who think one speaks the truth and truly represents the Church.
Funny, my cousin the fundamentalist basically said the same thing to me, and my answer remains: “Was I supposed to tell God, ‘No?’” He called me for over 30 years and I couldn’t answer. Frankly, I don’t recommend telling God “No”…
One answers the Call, by first going through discernment with an orthodox Spiritual Director who would guide you to understand the plan that God has for you. If there truly is a Call, it being sustained over the many years does play some part (a small part really) in whether or not there is a vocation. If in discerning with a Spiritual Director one is not called, all those years are just illusions really and maybe even temptations by Satan. As such, when all is said and done how long one is called for, before one answers is a minor factor. More importantly is it being sustained through the seminary formation right to the point of ordination, yet even then the discernment doesn’t even stop. But of course I am referring to the a vocation of a male cleric.
Further, you have already said ‘No’ to God by going down this path you have taken. You have rejected those and their successor, whom Jesus himself spoke of “He that heareth you, heareth me; and he that despiseth you, despiseth me; and he that despiseth me, despiseth him that sent me.”
