I'm sure it wasn't only because the Personalist Project is based here. :) Even so, it was great to hear that the 2015 World Meeting of Families will take place in the City of Brotherly Love. I can see this becoming ground zero in the battle to preserve traditional marriage in America, especially in the face of growing pressure from the SSM lobby.
The Pope also stressed the importance of family life built upon a man and woman who are married to each other. This is because God “created us male and female, equal in dignity, but also with respective and complementary characteristics, so that the two might be a gift for each other, might value each other and might bring into being a community of love and life.”
Archbishop Chaput reinforces the impression in his official announcement.
I am so grateful to the Holy Father that he has chosen Philadelphia...It's fitting that this gathering, which celebrates the cornerstone of society, will take place in America's cradle of freedom...The family is founded on a deep and loving union between one man and one woman for mutual support and the nurturing of children. This meeting in Philadelphia will be a wonderful opportunity to highlight the family as the basic evangelizing unit of the Church. Every effort to promote marriage and the family serves not only the Church, but also the common good.
