The Church teaches very unequivocally that for the valid conferring of the sacraments, the minister must have the intention of doing at least what the Church does. This is laid down with great emphasis by the Council of Trent (sess. VII). The opinion once defended by such theologians as Catharinus and Salmeron that there need only be the intention to perform deliberately the external rite proper to each sacrament, and that, as long as this was true, the interior dissent of the minister from the mind of the Church would not invalidate the sacrament, no longer finds adherents. The common doctrine now is that a real internal intention to act as a minister of Christ, or to do what Christ instituted the sacraments to effect, in other words, to truly baptize, absolve, etc., is required.
