“It is unlawful to follow one line of conduct in private life and another in public, respecting privately the authority of the Church, but publicly rejecting it; for this would amount to joining together good and evil, and to putting man in conflict with himself; whereas he ought always to be consistent, and never in the least point nor in any condition of life to swerve from Christian virtue.”  Leo XIII, Immortale Dei, “On the Christian Constitution of States,” paragraph 47
