The solemnity of All Saints' Day is followed by the day dedicated to the memory of the those that the Church evokes each day in its prayer. The Christians believe that death is only one passage, because Jesus said: "Do not marvel at this; for the hour is coming when all who are in the tombs will hear his voice and come forth, those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of judgment"(John 5, 2829).
Or: "I am the resurrection and the life; he who believes in me, though he die, yet shall he live, and whoever lives and believes in me shall never die" (John 11, 25-26).

And Paul writes in addition:

"As by a man came death, by a man has come also the resurrection of the dead. For as in Adam all die, so also in Christ shall all be made alive. But each in his own order: Christ the first fruits, then at his coming those who belong to Christ. Then comes the end, when he delivers the kingdom to God the Father after destroying every rule and every authority and power. For he must reign until he has put all his enemies under his feet […] If the dead are not raised, "Let us eat and drink, for tomorrow we die" (1 Corinthians 15, 21-34).
