Le Pelerinage de Lourdes §51

⁵¹ Just as the Immaculate, compassionate of our miseries, but discerning our real needs, came to men to remind them of the essential and austere steps of religious conversion, so the ministers of the Word of God should, with supernatural confidence, point out to souls the narrow road which leads to life. They will do this without forgetting the spirit of kindness and patience which they profess, but also without concealing anything of the Gospel's demands. In the school of Mary they will learn to live not only that they may give Christ to the world, but also, if need be, to await with faith the hour of Jesus and to remain at the foot of the cross.
