If the "church" sends the HS, that means that you or me, or Mrs Grundy who hates everybody is in control. That is perfectly ridiculous as well as totally unbiblical.
I don't understand why, or even what control are you talking about. If what you are trying to say is that the priest performing a sacrament might not mean it, then the Church teaches that the sacrament remains valid despite the disposition of the priest. It is always the same sacrament regardless of the priest, presuming it is validly confected.
