Pope Francis suggests that people maintain bonds with the dead by praying for them:
257. One way of maintaining fellowship with our loved ones is to pray for them.(Catechism 958) The Bible tells us that “to pray for the dead” is “holy and pious” (2 Macc 12:44-45). “Our prayer for them is capable not only of helping them, but also of making their intercession for us effective”.(Ibid.)The Book of Revelation portrays the martyrs interceding for those who suffer injustice on earth (cf. Rev 6:9-11), in solidarity with this world and its history.
Some saints have offered or inspired important considerations:
Some saints, before dying, consoled their loved ones by promising them that they would be near to help them. Saint Therese of Lisieux wished to continue doing good from heaven.* Saint Dominic stated that “he would be more helpful after death… more powerful in obtaining graces”.** These are truly “bonds of love”,(Catechism 957) because “the union of the wayfarers with the (sisters and brothers) who sleep in the Lord is in no way interrupted… [but] reinforced by an exchange of spiritual goods”.(Lumen Gentium 49)
*Cf. Therese of Lisieux, Derniers Entretiens: Le “carnet jaune” de Mère Agnès, 17 July 1897, in Oeuvres Complètes, Paris, 1996, 1050. Her Carmelite sisters spoke of a promise made by Saint Therese that her departure from this world would be “like a shower of roses” (ibid., 9 June 1897, 1013).
