Our holy religion was not invented by human reason, but was most mercifully revealed by God; therefore, one can quite easily understand that religion itself acquires all its power from the authority of God who made the revelation, and that it can never be arrived at or perfected by human reason. In order not to be deceived and go astray in a matter of such great importance, human reason should indeed carefully investigate the fact of divine revelation. Having done this, one would be definitely convinced that God has spoken and therefore would show Him rational obedience, as the Apostle very wisely teaches. For who can possibly not know that all faith should be given to the words of God and that it is in the fullest agreement with reason itself to accept and strongly support doctrines which it has determined to have been revealed by God, who can neither deceive nor be deceived? (Bl. Pius IX Qui Pluribus)
