So it's ok? Does it apply to schismatics "blessing" it?
Can heretics and schismatics bless anything? A priest is a priest is a priest. I think if a priest is validly ordained and becomes an heretic or schismatic he can still administer the sacraments in an emergency so maybe the blessing is valid but if he's not validly ordained there is no blessing to begin with. Just my opinion.
Make your purchase and have it blessed
