The _silent propaganda_ is the spreading of Catholic ideas through the contact of our every day life with those who are not of our own Faith. Willingly or unwillingly we are bound to leave an impression of our belief in the business and social circles into which our life is cast. Our silence and abstention alone often militate against the Church. Let then the purity and spirituality of our lives, the honesty of our commercial relations, the sanctity of our home, bear witness to the sacredness of our religion and to the seriousness of its teachings. A true Catholic life is in itself a living antithesis of the prevalent neo-pagan ideals, and stands as the best proof of our Faith's sincerity and of the depth of its conviction. "If life is the test of thought rather than thought the test of life," wrote Van Dyke, "we should be able to get light on the real worth of a man's ideals by looking at the shape they would give to human existence if they were faithfully applied." For, as Cromwell said, "The mind is the man." The participation in civic, social and national activities will afford the occasion of meeting our non-Catholic neighbours. This personal and repeated contact, particularly with the leaders of the community, on occasions when the best brains can concentrate together without clash of principle, is, in our humble estimation, of the greatest value. The participation of the Knights of Columbus in war activities and reconstruction work is a striking illustration of this point. Nothing has more helped the Church in the American Republic, in breaking down the barrier of anti-Catholic prejudice, than the stand its Catholic laity took during and after the Great War. Have we not in Western Canada been rather remiss in our participation in public activities? If we have not had our share in public life, it has often been, we must confess, our own fault. The strength of the silent propaganda lies in its _persistency_ and _consistency_. A silent continuous and intelligent activity, and not a mere passivity, on the part of Catholics, is what characterizes this tremendous force. Like the tide, it creeps from pebble to pebble, from rock to rock, submerging every thing under its conquering waters. The logic of Catholic life lends its consistency to this silent force. Our life is indeed the best proof of our principles. No one on the contrary does more harm to the Church than a Catholic whose life is not in harmony with his belief. The non-Catholic points to his life, with a sneer, and says: "See, he is no better than others!" This reasoning, we know is false, but for the unthinking masses, very often conclusive. This silent drive is the necessary background of the _open propaganda_ of which we would now say a few words.
