This is Tom here. That wasn't me above, though I agree with it.
Anyway my response is simple.
If there was no law enforcement to do this job, any normal parent would say no. Even with law enforcement most parents today would say no.
When the Church is restored the Thuc line Sacraments can be just conditionally redone. But they certainly wont be accepted with the situation as is when Rome becomes Catholic again.
Yes, the point is that it is inconceivable that our most prudent Mother, Holy Church, would, as Tom has said, leave the situation as it is without examining the question and rectifying the situation.
I have learned that the Church solves things like this not only for the sake of justice, but for the sake of bringing peace of soul to reasonably disquieted consciences. Disquietude of soul, according to St. Francis de Sales, is the greatest evil underneath sin, and the Church in Her wonderful solicitude for Her children cares about this deeply as well.
