The poster presents a phrase by Fr. Luigi Giussani:

A “particular history is the keystone of the Christian conception of man, of his morality, in his relationship with God, with life, and with the world. Our hope is in Christ, in that Presence that, however distracted and forgetful we be, we can no longer (not completely, anyway) remove from the earth of our heart
because of the tradition through which He has reached us.”
