"But the fundamental reason for the Year of Faith is to call all Catholics to the act of faith, that is, to the fundamental reality of our relationship with Jesus Christ, to a joyful witnessing of our faith in him, and to a courageous adherence to what Christ, in and through his Church, teaches us about how to live and how to love. The Holy Father is concerned that, in some cases, Catholics in their very laudatory focus on “the social, cultural and political consequences” (Porta fidei, 2) of faith, may lose sight of the very foundation which leads to those consequences.
We ourselves need to nourish and strengthen our faith thorough the sacraments, through prayer, through study of Catholic doctrine, especially the Catechism of the Catholic Church. If we don’t nourish our faith, then little by little we will lose the capacity to witness, and our work and our ministries will gradually become indistinguishable from any kind of humanitarianism, however praiseworthy that may be."
