20 If native priests are well instructed in these practical matters and serious disciplines, and if they overcome difficulties and are equipped to take the right course of action, they will be able, under guidance of their bishops, to make highly valuable contributions. In particular, they will find a more sympathetic audience among the educated citizens of their own countries and will be able to attract them to the Christian truth, in the manner of the famous missionary, Matthew Ricci. This will happen especially in those countries which possess an ancient and highly developed civilization of their own. Indeed, local priests are entrusted with the mission of "bringing every mind into captivity to the obedience of Christ," (37) as Paul, that incomparable missionary and apostle of the people, affirmed; thus, they will also be "held in great honor by the members of the intellectual elite of their country."
