Has the potential to lead to chaos, since any sacrament or rite could be rendered null and void upon revelation of wrongdoing on the part of the clergyman performing it. It is for the best that this school of thought was anathematized and died out.
Look at the angst going on in the Catholic Church right now after the CDF ruled recently that a bunch of baptisms are null because of the verbal formula used. Then imagine if they could rule the same thing if the priest or deacon doing the baptism had
ever committed a sufficiently grave sin. Complete pandemonium.
