Nonetheless, this mystery [of "the fullness of time"] constantly clashes with the dramatic experience of human history. Each day, as we seek to be sustained by the signs of God’s presence, we encounter new signs to the contrary, negative signs which tend to make us think instead that He is absent. The fullness of time seems to fade before the countless forms of injustice and violence which daily wound our human family. Sometimes we ask ourselves how it is possible that human injustice persists unabated, and that the arrogance of the powerful continues to demean the weak, relegating them to the most squalid outskirts of our world. We ask how long human evil will continue to sow violence and hatred in our world, reaping innocent victims. How can the fullness of time have come when we are witnessing hordes of men, women and children fleeing war, hunger and persecution, ready to risk their lives simply to encounter respect for their fundamental rights? A torrent of misery, swollen by sin, seems to contradict the fullness of time brought by Christ. Remember, dear pueri cantores, this was the third question you asked me yesterday: how do we explain this… even children are aware of this.
And yet this swollen torrent is powerless before the ocean of mercy which floods our world. All of us are called to immerse ourselves in this ocean, to let ourselves be reborn, to overcome the indifference which blocks solidarity, and to leave behind the false neutrality which prevents sharing.
--Pope Francis, homily, Jan. 1, Solemnity of the Mother of God and World Day of Peace
