There are several little breastplates thus worn by Catholics to shield them from spiritual evil and bodily calamity. The chaplet of beads, known as the rosary, is well known. The brown scapular of St. Mary of Mount Carmel is made of small pieces of cloth connected by long strings, and is worn over the shoulders in imitation of the brown habit of the Carmelite friars. Then there are the Medal of Our Lady of Perpetual Succour, a reproduction of the wonderful picture discovered by the Redemptorist Order in Rome; and the Miraculous Medal of Our Lady, revealed by the Immaculate Virgin to Catherine Laboure, Sister of Charity of St. Vincent de Paul, in Paris. Another is the "Agnus Dei" ("Lamb of God"), a small disc of wax, impressed with the figure of a lamb supporting a cross, and blessed by the Pope, which is the most ancient of the sacramentals, or holy objects worn, used or preserved by Catholics for devotional purposes. But what is now perhaps the most esteemed of all is the Badge of the Sacred Heart. On an oval piece of red cloth is printed a picture of Jesus, standing before a cross, with His bleeding heart, encircled by thorns and flames, exposed on His breast. The badge is emblematical of the sufferings of Jesus for the love of and redemption of mankind. It is the cognisance of a world-wide league, known as the Apostleship of Prayer, conducted by the Society of Jesus, and having, it is said, a membership of 25,000,000 of all nations. The promotion of these special devotions in the Catholic Church has been assigned to different Orders: such as the rosary to the Dominicans; the scapular to the Carmelites; the Way of the Cross to the Franciscans. So the spread of the devotion of the Sacred Heart is the work of the Jesuits. The headquarters of the Apostleship of Prayer in this country is the house of the Jesuits in Dublin, who publish as its organ a little monthly magazine called _The Messenger_. There has been so enormous a demand for the badge since the war broke out that the Jesuits have circulated a statement emphasising that it is not to be regarded as "a charm or talisman to preserve the wearer from bullets and shrapnel." To wear it in this spirit would, they say, be "mere superstition." "What it stands for and signifies is something far nobler and greater," they also say. "It is, in a sense, the exterior livery or uniform of the soldiers and clients of the Sacred Heart of Jesus, King of heaven and earth, just as the brown scapular is the livery of the servants and soldiers of Mary, heaven's glorious Queen. As such it procures for those who wear it in the proper spirit the grace and protection of God; and the scapulars the special protection of Mary, much more than the livery or uniform of a country procures for those who fight under its flag the help and protection of the nation to which they belong."
