All the excuses and arguments against it usually boil down to finances… But the Orthodox married clergy seem to he able to survive just fine. If they can, why can’t we?
Its more than fiances, its logistics too.
The Eastern Churches (whether Orthodox or Catholic) typically have smaller parishes than Roman Rite Catholics do. They also typically have 1 priest per parish in diocesan ran parishes - making it easy for a family to live in the rectory.
Everything in the Eastern Churches was built around married diocesan clergy. From parish size to the way the seminary curriculum is set up, everything has been built around this.
If the Catholic church wanted to make this the norm for Roman Rite parishes, it will be a major logistical nightmare for many years.
From housing issues to total revamp of seminary curriculum. Each diocese would have to plan and implement married clergy once they were ready. It would be logical mess if the whole Latin Church or an entire national bishop’s conference tried to implement this all at once.
So while it technically could be done; I think (1) it’s far more difficult than many people think, (2) it won’t solve all the issues people think a married clergy will fix, and (3) it will introduce different problems we currently do not have.
Finally, there are several very good reasons why many married priests (if not most) say a married priesthood would be a mistake for the Roman Rite in most dioceses today.
