"Jen was exposed to the Greek Orthodox religion growing up because that's her dad's background. Her first marriage, to Brad Pitt, was a huge, extravagant affair, but it was not a church wedding. Jen isn't overly religious, but she wants one now."
In many culturally-rooted Orthodox churches (Indian, Greek, Russian, etc), this is a very common observation i.e., the Sacrament of Marriage given to a couple who is not spiritually connected to the Church. The tragedy in most cases is the community and the priest fails in their Spiritual obligation to the new couple and do not leverage their interest in the Church to bring that couple closer to Christ.
Dr. Bradley Nassif wrote on the Orthodox church forgetting it's evangelical roots, and it's almost impossible to argue this point. Our Church must wake up and respond to the natural tendency of people to search for God as they get older in order for a healthy growth, as in almost every cases the person's search begins with what they had experienced in their childhood.
