That is not evidence. Only on a man’s own admission could we know that he is not limiting his children by practicing continence, he and his wife agreeing to abstain from marriage rights by mutual consent. But even if it be true that many Catholics sin in this manner, the fact that they sin could not justify the same sin in others. All cannot break a law because some do. Nor do such Catholics think themselves justified. They know they are sinning just as men sin by breaking any other law of God. Protestants have admitted to me over and over again that their consciences have protested against such conduct, and that the Catholic law is undoubtedly right.
