So, in one man's opinion, Michael Davies only, "appears to be saying that the new ordination rite is at best weak," but does not actually say it is "weak". Unless he says, exactly why he believes it to be weak, rather than just appearing to say it, according to someone else's interpretation, then it's useless to bring Davies' opinion into the discussion. According to Trent, "materia et forma sacramenti essentia efficitur". If there is a valid matter and a form that expresses the intention of the rite, then the rite is certainly valid. Full Stop.
