“Death would gladly walk through the realm of joy, He would gladly press his hand on flowery brows. In ashes tomorrow and torn garments, With bowed head, the memory of joy will be a reproach and a pain to us. Our games are followed by funeral processions; Saturnalia can be our cradle, Woe to us!, of songs of the dead alone!” Text: Victor HUGO, (1802 – 1885): “Ode sur la mort du duc de Berry” (1820)

"God loves every soul with an undying love. He approaches each one with repeated, unspeakably patient offers of redemption. Even a small sign of love is enough for him to forgive and redeem. Our dear departed ones lacked a life preserver for the body; but the spiritual life preserver was not lacking, the breath of God in which the soul can clothe itself in a tiny moment, much more quickly than the body could." (Text by Albino Luciani / Pope John Paul I)
