According to Benedict XVI, "a good and effective training" in the area of charity must "aim at better qualifying people who work in different charitable activities, so that they may be, also and above all, the witnesses of evangelical love". "They are called to be the witnesses of the value of life, in all its forms he highlighted , especially by defending the life of the weak and the sick, following the example of the Blessed Mother Teresa of Calcutta, who loved and took care of dying people, because life is not measured against its efficiency, but it is valuable at all times and for everyone". In addition, he added, "they are called to be the witnesses of love, that is, of the fact that we are fully men and women insofar as we live for helping others; that nobody can live or die for oneself; that happiness is not found in the loneliness of a life withdrawn onto itself but in offering oneself up". Finally, he said, "those who work in ecclesial activities must be the witnesses of God, who is fullness of love and who invites one to love". Then the Pontiff praised the initiative of the Papal Council Cor Unum of promoting next June a course of spiritual exercises in Guadalajara for the presidents and directors of charitable organisations of the American continent. He wished this may be extended to other regions of the world as well.” “
