“All have come to affirm their commitment to the family as the foundation of a fruitful life, the place where we first learn to love, to share and to be agents of charity and justice in the world,” says Chaput.

Paglia, who is the president of the Vatican’s Pontifical Council for the Family, which is overseeing the event, says Pope Francis’ arrival this weekend to conclude the conference will be a joyful time for all.
