Neglect of the elderly or their outright rejection are intolerable. Their presence in the family, or at least their closeness to the family in cases where limited living space or other reasons make this impossible, is of fundamental importance in creating a climate of mutual interaction and enriching communication between the different age-groups. It is therefore important to preserve, or to re-establish where it has been lost, a sort of "covenant" between generations. In this way parents, in their later years, can receive from their children the acceptance and solidarity which they themselves gave to their children when they brought them into the world. This is required by obedience to the divine commandment to honour one's father and mother (cf. Ex 20:12; Lev 19:3). But there is more. The elderly are not only to be considered the object of our concern, closeness and service. They themselves have a valuable contribution to make to the Gospel of life. Thanks to the rich treasury of experiences they have acquired through the years, the elderly can and must be sources of wisdom and witnesses of hope and love.
