ERROR VS. PERSON IN ERROR

This love and good will, to be sure, must in no way render us indifferent to truth and goodness. Indeed love itself impels the disciples of Christ to speak the saving truth to all men. But it is necessary to distinguish between error, which always merits repudiation, and the person in error, who never loses the dignity of being a person even when he is flawed by false or inadequate religious notions.
