Pope Pius XII, in Chosen Laymen, an Address to the Third Order of St. Dominic (1958), said, "The true condition of salvation is to meet the divine invitation by accepting the Catholic 'credo' and by observing the commandments. But the Lord expects more from you Dominicans, and the Church urges you to continue seeking the intimate knowledge of God and His works, to search for a more complete and valuable expression of this knowledge, a refinement of the Christian attitudes which derive from this knowledge."
