144. Of what miracles of raising the dead do the gospels relate?

The gospels describe three cases in which Jesus brought dead human beings back to life: the daughter of Jairus (cf. Matthew 9: 18-26), the young man of Nain (cf. Luke 7: 13-15), and Lazarus, the brother of Mary and Martha (cf. John 11: 1-44).
The miracles in which Jesus raises the dead make it clear that Jesus Christ is also Lord over death. At the same time they are a reference to the hope that the dead will one day resurrect to eternal life.
