"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)
