Context

“XLVI. Christ (Luke viii.) says, “Unto you it is given to know the mysteries of the kingdom of God.” Here a man might ask, What mystery is that? If a mystery, why do you preach it? Whereunto I answer: A mystery is a thing hidden and secret; the mysteries of the kingdom of God are such things as lie hidden in the kingdom of God; but he that knows Christ aright, knows what God’s kingdom is, and what therein is to be found. They are mysteries, because secret and hidden from human sense and reason, when the Holy Ghost does not reveal them;” source
