106 Venerable Brethren, the hour when this Our first Encyclical reaches you is in many respects a real "Hour of Darkness" (cf. Saint Luke xxii. 53), in which the spirit of violence and of discord brings indescribable suffering on mankind. Do We need to give assurance that Our paternal heart is close to all Our children in compassionate love, and especially to the afflicted, the oppressed, the persecuted? The nations swept into the tragic whirlpool of war are perhaps as yet only at the "beginnings of sorrows" ( Saint Matthew xxiv. 8), but even now there reigns in thousands of families death and desolation, lamentation and misery. The blood of countless human beings, even noncombatants, raises a piteous dirge over a nation such as Our dear Poland, which, for its fidelity to the Church, for its services in the defense of Christian civilization, written in indelible characters in the annals of history, has a right to the generous and brotherly sympathy of the whole world, while it awaits, relying on the powerful intercession of Mary, Help of Christians, the hour of a resurrection in harmony with the principles of justice and true peace.
